Quick answer

Clean acrylic charms with a soft microfiber cloth, lukewarm water, and a drop of mild dish soap. Never use paper towels, alcohol wipes, or abrasive sponges — they cause micro-scratches that dull the print. For Wuthering Waves Tidal Letters charms, the same gentle method preserves the artwork and clear acrylic finish.

Why acrylic charms scratch easily

Acrylic is a soft plastic that scratches faster than glass. Even a paper towel can leave fine swirl marks because the fibers are rough at a microscopic level. Dust particles trapped on the surface act like sandpaper when rubbed. That is why the cleaning method matters more than the cleaning frequency for acrylic charm care.

What you need (and what to skip)

Grab a microfiber cloth (the kind used for eyeglasses), lukewarm water, and a drop of mild dish soap. Avoid window cleaners, hand sanitizer, nail polish remover, or anything with alcohol or ammonia — those chemicals cloud the acrylic and can lift printed designs. Paper towels and rough sponges are also out.

Step-by-step: How to clean an acrylic charm safely

  1. Step 1: Blow off loose dust first: Use a can of compressed air or gently blow on the charm to remove dust. Do not wipe a dry charm — that grinds dust into the acrylic and creates scratches. Common mistake: wiping a dusty charm with a dry cloth. Always remove loose particles first.
  2. Step 2: Dampen a microfiber cloth with soapy water: Mix a few drops of mild dish soap into a bowl of lukewarm water. Dip the corner of a microfiber cloth, then wring it out until it is barely damp. Never spray water directly onto the charm — moisture can seep into the metal keychain loop or between the acrylic layers if it is a layered design. Checkpoint: the cloth should feel damp, not wet. If water drips, wring harder.
  3. Step 3: Wipe in one direction, not circles: Gently wipe the charm from top to bottom in straight strokes. Circular motions leave visible swirl marks on clear acrylic. For stubborn smudges, let the soapy cloth sit on the spot for a few seconds before wiping. Common mistake: rubbing in circles. Straight strokes keep the surface optically clear.
  4. Step 4: Rinse with a separate damp cloth: Use a second microfiber cloth dampened with plain water to remove any soap residue. Leftover soap can dry into a cloudy film that dulls the print. Checkpoint: hold the charm up to light — if you see a haze, you missed a rinse step.
  5. Step 5: Air dry on a soft surface: Lay the charm on a clean, soft towel or microfiber cloth. Let it air dry completely before reattaching it to a bag or display. Do not use a hair dryer — heat can warp the acrylic. Final tip: once dry, store the charm in a dust-free pouch or box to keep it clean longer.
