I’ve spent hundreds of sessions rolling polyhedral dice across kitchen tables, hardwood floors, and the occasional stone countertop, and I’ve seen exactly what happens when dice aren’t cared for. Chipped edges, cloudy faces, and inked numbers that fade into illegibility are the three most common problems, and they’re all preventable.
This guide covers how to keep dice from chipping and clouding over time, no matter what material they’re made from. I’ll walk you through the science behind both problems, the cleaning methods that actually work for each material, and the storage habits that keep your dice collection looking like the day you bought it. If you roll D&D, Pathfinder, Call of Cthulhu, or any other tabletop RPG, the tips below apply to your set.
By the end, you’ll have a complete care routine: a trusted rolling surface, a material-safe cleaning method, and a storage system that protects every die from humidity, impact, and UV light. Let’s start with the quick reference so you can find answers fast.

Quick Reference: Dice Care Cheat Sheet by Material
Before we dive deep, here’s the cheat sheet I wish I’d had years ago. It maps every common dice material to the safest cleaning method, the ideal storage solution, and the things you should never do. Use this table whenever you’re unsure about a new set in your collection.
| Material | Best Cleaning Method | Best Storage | Avoid |
|---|---|---|---|
| Resin | Mild soap and lukewarm water, soft cloth | Velvet pouch or foam-lined case | Alcohol, acetone, abrasive scrubbers |
| Acrylic | Mild soap and water, microfiber cloth | Individual foam slots | Solvents, high heat |
| Metal (zinc, aluminum) | Dry microfiber cloth, mild soap if needed | Felt-lined dice vault | Alcohol, prolonged moisture |
| Metal (copper, steel) | Dry cloth, jewelry polish sparingly | Anti-tarnish bag | Humidity, acidic sweat |
| Gemstone | Dry soft cloth only | Padded velvet box, individual slots | Water, oils, sudden temperature changes |
| Ceramic | Soft damp cloth, mild soap | Cushioned pouch | Hard impacts, harsh chemicals |
| Wood | Dry cloth, occasional mineral oil | Breathable cloth bag | Soaking, direct sunlight |
| Liquid core | Soft damp cloth on outer shell only | Upright case, no pressure on faces | Cold temperatures, piercing pressure |
| Glow-in-the-dark | Damp cloth, no solvents | Dark pouch to preserve glow | UV bleaching, harsh cleaners |

What Causes Dice to Chip and Cloud?
Chipping and clouding are two different problems with different causes, and treating them the same way is the fastest way to ruin a set. Once you understand what each one actually is, the prevention steps make a lot more sense.
Why Dice Chip
Chips happen when force concentrates on a small point. Sharp edges, raised numbers, and corners are the most vulnerable because they don’t have a flat surface to absorb impact. When a d20 lands corner-first on a stone table, that corner takes the full force of the stop, and small pieces shear off.
Internal stress makes this worse. Cast resin, machined metal, and natural gemstone all have tiny internal stresses from the manufacturing or cutting process. A hard impact can release that stress along a fault line, causing a chip that doesn’t even touch the impact point. That’s why two dice of the same material can behave very differently.
Repeated micro-impacts are sneaky. A single hard drop rarely causes a chip, but thousands of rolls on a hard surface cause microfractures that eventually become visible chips. This is why a soft rolling surface is the single most important investment you can make for chip prevention.
Why Dice Cloud
Clouding is a milky, hazy, or opaque film that builds up on dice surfaces over time. It’s most visible on clear resin, acrylic, and gemstone dice, but it can affect any material. There are three common causes, and most sets suffer from all three at once.
Micro-scratches are the biggest contributor. Every roll, every wipe, every nudge against another die creates tiny scratches on the surface. Individually, they’re invisible. Together, they scatter light and create that cloudy look. This is the same reason eyeglasses get hazy without proper cleaning.
Chemical exposure attacks many dice. Skin oils, hand sanitizer residue, sunscreen, and perfume all leave films that react with dice surfaces. Resin and acrylic are especially vulnerable because they’re slightly porous at the microscopic level. Over time, these films build up and become hard to remove with a simple wipe.
UV degradation is the slow burner. Direct sunlight and even bright indoor lighting break down pigments and resins over months and years. The result is yellowing on clear dice, fading on painted numbers, and a general loss of clarity. UV exposure is the clouding problem that’s hardest to reverse, but easiest to prevent.
Why Edges and Numbers Are Most Vulnerable
Sharp edges and engraved numbers are stress concentrators. They’re the points where manufacturing imperfections tend to settle, and they’re the first to make contact during a roll. That’s why you’ll see chips on the corner of a d4 or the raised “6” face of a d6 long before the flat face shows any wear.
How to Keep Dice From Chipping During Play?
The fastest way to prevent chipping is to change how and where you roll. I’ve rolled dice on bar tops, hotel desks, and even a concrete patio (don’t recommend), and the difference a quality surface makes shows up in the dice within a few sessions.
Use a Felt-Lined Dice Tray
A felt-lined dice tray is the single biggest upgrade for chip prevention. The felt absorbs impact, the raised walls keep dice contained, and the soft surface prevents corner-first contact. I’ll use a tray for any set I’m worried about, especially metal and gemstone dice where chips are most visible.
Look for trays with a removable felt insert. Felt wears down over time, and being able to swap it out extends the life of the tray and keeps rolling consistent. Deep trays (at least 1.5 inches) prevent dice from bouncing out during enthusiastic rolls.
Choose a Soft Rolling Surface
If a tray isn’t available, a rolled-up battle mat, a piece of foam board, or even a folded t-shirt works as a backup. The key is softness. Avoid rolling directly on wood, glass, stone, or any hard surface, especially for premium dice.
For casual play at home, I keep a dedicated 12-inch felt square on the table. It’s cheap, portable, and provides enough cushioning for most materials. For travel, a leather dice tray rolls up flat in a bag.
Spread Out the Set
Tossing seven dice together in a clump creates dice-on-dice impacts that cause chips. Spread your roll across the tray so each die lands in its own space. This is especially important for sharp-edged metal dice, which can scratch and chip each other on impact.
Roll With Intention
Hard rolls cause more damage than gentle rolls. A two-foot drop onto a soft surface is much gentler than a four-foot drop onto a hard table. Train yourself to roll close to the surface. The “exploding critical hit” toss might feel dramatic, but it shortens dice life.
How to Clean Dice by Material Type?
Cleaning is where most people accidentally damage their dice. The wrong cleaner can dissolve resin, oxidize metal, etch gemstone, or strip paint from numbers. Below is the exact method I use for each material, including what to never use.
Cleaning Resin and Acrylic Dice
Resin and acrylic are the most common dice materials, and they’re forgiving if you stick to mild soap and water. Fill a bowl with lukewarm water, add a drop of dish soap, and dip a soft microfiber cloth. Wipe each die gently, rinse briefly under cool water, and dry with a lint-free cloth.
What to avoid: rubbing alcohol, acetone, nail polish remover, and any abrasive scrubber. These will craze the surface, leaving permanent tiny cracks that look exactly like clouding. For inked numbers, use a soft toothbrush dipped in soapy water to get into the grooves without scrubbing the paint.
Cleaning Metal Dice
Metal dice need a lighter touch. For routine cleaning, a dry microfiber cloth is enough. Wipe each die after a session to remove skin oils before they tarnish the surface. If a deeper clean is needed, use a barely damp cloth with a tiny amount of mild soap, then dry immediately.
For tarnish on copper or brass dice, a jewelry polishing cloth works, but use it sparingly. Aggressive polishing removes the patina and can wear down engraved numbers. Avoid alcohol entirely. It strips the protective coating on most metal dice and accelerates oxidation.
Painted or enamel metal dice need extra care. The paint is the most fragile part. Use only a soft dry cloth, and never soak. If the numbers start to fade, an acrylic paint marker in the matching color can refresh them, but be sure to let the paint cure fully before the next roll.
Cleaning Gemstone Dice
Gemstone dice like amethyst, obsidian, jade, and quartz should rarely get wet. Water can seep into micro-fractures and cause long-term damage, especially in softer stones. Use a dry, soft cloth for routine cleaning, and brush out engraved numbers with a soft dry toothbrush.
For deeper cleaning, a cloth barely dampened with distilled water works, but dry immediately. Never use soap, oil, or chemical cleaners on natural stone. Treat gemstone dice like fine jewelry, because that’s essentially what they are.
Cleaning Ceramic and Wood Dice
Ceramic dice are surprisingly tough but their painted numbers aren’t. Use a soft damp cloth with mild soap, and pat dry. Avoid abrasive cleaners, which can scratch the glaze and dull the finish.
Wooden dice need the opposite approach: avoid water entirely. Use a dry cloth for routine cleaning, and once or twice a year, treat them with a tiny amount of mineral oil or beeswax to prevent the wood from drying out. This keeps the grain from cracking and preserves the finish.
Cleaning Liquid Core and Glow-in-the-Dark Dice
Liquid core dice have a sealed outer shell with fluid inside. Don’t submerge them, and don’t apply pressure to the faces. A barely damp cloth on the outer shell is the safest method. Avoid cold temperatures, which can cause the fluid to expand and crack the seal.
Glow-in-the-dark dice use phosphorescent material that degrades with UV exposure and harsh cleaners. Clean with a damp cloth only, and store them in a dark pouch to preserve the glow effect. Avoid alcohol, which can break down the phosphorescent layer over time.
Best Storage Solutions to Prevent Damage
Storage is the other half of the care equation. Even perfect dice will chip and cloud if you throw them in a loose bag. The right storage solution depends on your collection size, your materials, and how often you play.
Dice Bags and Pouches
A soft pouch is the baseline storage solution for any dice set. Velvet and microfiber linings are gentle on surfaces and help prevent micro-scratches when dice rub against each other. Leather is stylish but can be abrasive on soft materials if the dice are damp.
For individual dice or small sets, a drawstring velvet pouch is enough. For larger sets, choose a pouch with internal dividers so dice don’t pile up against each other. I’ve seen too many gemstone d20s chip their points against a metal d4 in a shared pouch.
Dice Vaults and Cases
A dice vault is a hard case with foam or felt inserts that hold each die in its own slot. They’re ideal for collectors and for transporting multiple sets safely. Look for a vault with separate compartments for each die, foam that’s firm enough to prevent movement, and a soft lining that won’t scratch polished surfaces.
For metal dice, a felt-lined case prevents both chipping and the dreaded metal-on-metal clink that can dull edges. For gemstone dice, individual compartments are essential. Two stones grinding against each other in a bag can chip both.
Stackable trays with foam inserts are great for organized collections. Each tray holds a full set, and the foam keeps dice locked in place during transport. I’ve moved three full trays across the country without a single chip, which is more than I can say for dice in loose bags.
Display Cases
If you display your collection, choose a case with UV-protective glass or acrylic. Direct sunlight fades pigments and clouds clear resin over months. A case with a tinted front panel filters UV and keeps dice looking new.
Add a small desiccant pack to any display case that isn’t in a climate-controlled room. Humidity is the silent killer of metal and gemstone dice. A silica gel packet tucked into the corner absorbs moisture and prevents tarnish and micro-fractures, especially in coastal or seasonal-humidity climates.
Storage Materials Compared
Velvet is gentle and widely available, but it can shed fibers that stick to sticky finishes. Microfiber is the most consistent and lint-free option. Foam is the firmest, best for travel, but can off-gas chemicals that affect some resins. Leather is durable and looks good, but it can dry out dice and scratch softer surfaces.
For most collections, a microfiber lining is the safest all-around choice. Pair it with a hard exterior for travel, and add a desiccant pack for any set stored longer than a week.
Special Care for Unique Dice Types
Some dice need extra-special treatment. Below are the unique cases I’ve handled most often, and the habits that keep them looking great.
Liquid Core Dice
Liquid core dice use mineral oil, distilled water, or glycerin inside a sealed cavity. The seal is the weakest point. Heat and pressure can crack the seal, so avoid leaving them in a hot car, near a radiator, or in a backpack under heavy books. Store upright with no pressure on the faces, and roll gently.
Glow-in-the-Dark Dice
The phosphorescent pigment in glow dice is sensitive to UV light and to harsh chemicals. Store them in a dark pouch between sessions to preserve the glow. Clean only with a damp cloth, and avoid any cleaner that contains alcohol or ammonia.
Vintage and Collectible Dice
If you have vintage dice from the 1970s, 1980s, or early 1990s, treat them as collectibles. Minimal handling is the goal. Store them in archival tissue or soft pouches, and avoid any cleaning beyond a dry soft cloth. Acrylic and resin formulas from those eras are more brittle than modern materials, and aggressive cleaning can wreck them.
Weighted and Precision Dice
Weighted dice often have metal cores or inserts. They can chip unevenly if dropped, which throws off the balance. Always use a soft surface, and test balance annually with the saltwater method I describe below.
How to Test Dice for Balance at Home?
Even with perfect care, dice can become unbalanced over time. A chip on one side, a tiny air bubble in the resin, or a settling metal insert can skew the roll. Testing is the only way to know if your dice are still fair.
The Saltwater Float Test
Fill a tall glass with water and add table salt until a small chunk of die can float. Drop each die into the water and watch which face lands up. A balanced die will land on each face roughly equally over many drops. If one face consistently floats up, the die’s center of mass is shifted away from the geometric center, and the die is biased.
Test each die at least 20 times to get a meaningful sample. Mark the results in a notebook. If one face comes up more than 30% of the time, retire the die from gameplay and use it as a story prop or a display piece.
Visual Inspection
Hold each die up to a bright light and look for air bubbles, inclusions, or uneven color density. These are signs of internal flaws that can affect balance. Run your finger along every edge and corner. Even a tiny chip you can barely see can shift a die’s center of gravity.
When to Retire a Die
Retire a die if it fails the salt test consistently, if it has multiple chips on the same face, or if it rolls off the table more often than not. Dice that bias gameplay ruin the experience for everyone at the table, and a retired die makes a great bookshelf decoration.
Repairing Chipped Numbers and Minor Damage
Not every chip requires a replacement. Touch-up methods can restore the appearance of most minor damage, especially on metal dice and resin sets.
Touching Up Painted Numbers
For metal dice with painted or enamel numbers, a fine-tip acrylic paint marker in the matching color can refill faded or chipped numbers. Clean the die first, let it dry, then carefully apply the paint in thin layers. Let each layer cure fully before adding the next. Once filled, seal with a thin coat of clear matte acrylic to protect the paint.
For resin dice with painted numbers, the same method works, but test the paint on a hidden face first. Some resins react with acrylic paint and cause discoloration. If the test fails, use a UV-curing resin paint instead.
Polishing Minor Surface Scratches
Light scratches on resin and acrylic can be polished out with a plastic polish like Novus 2 or a mild toothpaste. Apply with a microfiber cloth in small circles, then buff clean. Deep scratches can’t be fully removed, but proper polishing can make them less visible.
When to Replace Instead of Repair
Replace a die if it has a large chip, a cracked face, or a balance problem you can’t fix. Cosmetic damage on a balanced die is fine for gameplay. Functional damage on a beloved set is a sign to retire that die and let it rest in a display case.
FAQ
Why do dice get cloudy over time?
Dice get cloudy from micro-scratches, chemical exposure to skin oils and hand sanitizer, and UV degradation. These three causes work together to scatter light on the surface, creating a milky haze that builds up over months and years of use.
Can you clean dice with soap?
Yes, mild dish soap and lukewarm water is safe for resin, acrylic, ceramic, and most metal dice. Avoid soap on gemstone and wooden dice, which should be cleaned with a dry cloth only. Never use alcohol, acetone, or harsh chemicals on any dice.
How do you store dice to prevent chipping?
Store dice in velvet or microfiber pouches for small sets, or in foam-lined dice vaults with individual compartments for larger collections. Keep metal and gemstone dice separated from each other, add a desiccant pack to control humidity, and avoid stacking loose dice.
Can you fix chipped dice numbers?
Yes, you can refill chipped numbers with a fine-tip acrylic paint marker in the matching color. Clean the die first, apply paint in thin layers, let each layer cure, and seal with a clear matte acrylic. For large chips or balance issues, replacement is the better option.
How do I know if my dice are balanced?
Use the saltwater float test. Dissolve salt in a glass of water until a small chunk of die floats, then drop each die and record which face lands up. A balanced die shows roughly equal distribution across all faces over 20+ drops. Retire any die that consistently favors one face.
What is the best surface to roll dice on?
A felt-lined dice tray is the best surface. The felt absorbs impact, the raised walls contain dice, and the soft material prevents corner-first contact. For casual play, a felt square or rolled-up battle mat also works. Avoid wood, glass, and stone, which cause chips and clouding.
Conclusion
Knowing how to keep dice from chipping and clouding over time comes down to three habits: roll on a soft surface, clean with material-safe methods, and store dice in controlled environments. Once you build those habits, your dice will look and roll like new for years.
Start with one upgrade this week. A felt-lined tray, a microfiber pouch, or a saltwater balance test takes ten minutes and pays off for the life of your collection. Your dice (and your fellow players) will thank you.
