To clean modern mahjong tiles, wipe them with a soft, damp cloth, then dry them with another cloth. A little mild soap can help with grease. Do not soak them, and avoid harsh cleaners, which can wear away the paint. Store tiles dry, away from direct sun and heat. Older sets need more care: if you do not know what your tiles are made of, do not use water at all until you find out.
Modern tiles
- Spread out a towel.
- Wipe each tile with a soft cloth, slightly damp with water and a drop of mild soap.
- Wipe again with a clean, damp cloth.
- Dry right away, and let the tiles air-dry fully before you store them.
For dirt in the carved lines, a soft toothbrush can help. Be gentle, since colored paint can wear away.
What to avoid
- Soaking tiles in water.
- Bleach, strong solvents, or abrasive pads.
- Dishwashers, since heat and water may damage them.
- Leaving tiles in strong sun or a hot car, which can fade or warp them.
Storing your set
- Keep tiles in a case, and in a dry place.
- Store them flat if you can.
- Count your tiles once in a while.
- Keep spare tiles with the set.
Older sets
Antique tiles might be made of bone and bamboo, celluloid, or an early plastic. They can be fragile, and water or chemicals can damage them for good. Celluloid can also be flammable, so keep it away from heat. Some older materials are regulated, too.
For an older set:
- Dust gently with a soft dry brush.
- Do not soak or use cleaners.
- Keep the set out of direct sun and heat.
- If it may be valuable, ask a conservator or appraiser before doing anything.
