What You Need Before Starting
Gather these supplies: a soft-bristle makeup brush or clean paintbrush (1-inch flat works best), microfiber cloths, lukewarm distilled water, a small bowl, and optionally a can of compressed air. That is the entire kit. No specialty cleaners needed.
What to avoid completely: rubbing alcohol, acetone, nail polish remover, household all-purpose cleaners like Windex or 409, and anything containing solvents. These will strip paint, cloud the surface finish, or warp PLA plastic. Even diluted, they are not safe.
Step 1: Dry Dust Removal
Start with the soft brush and work from top to bottom. Use light, sweeping strokes to remove loose dust from all surfaces. Pay extra attention to crevices around the ears, between fingers, and along the base where dust settles into layer lines. A can of compressed air works well for hard-to-reach spots — hold it 6 inches away and use short bursts.
For figures displayed without a case, do this weekly. It takes 30 seconds per figure and prevents dust from building up into grime that requires wet cleaning.
Step 2: Gentle Wet Cleaning for Stubborn Spots
Dampen a microfiber cloth with lukewarm distilled water — not hot, not cold. Wring it out thoroughly so it is barely damp, not dripping. Gently wipe the affected area in one direction, not back and forth. For fingerprints and light grime, this alone handles it.
If a spot resists plain water, add one tiny drop of mild dish soap (Dawn or equivalent) to your bowl of distilled water. Dip a corner of the cloth, clean the spot, then immediately follow with a plain damp cloth to remove soap residue. Never submerge the figure or run it under a faucet.
Let the figure air dry completely before returning it to a display case. PLA does not absorb water, but trapped moisture in crevices can leave water spots.
Step 3: Maintaining the Finish After Cleaning
Once dry, inspect the figure under good light. If the matte finish looks uneven after cleaning, a single light pass with a dry microfiber cloth restores it. Do not buff aggressively — you will create shiny spots on matte-finished areas.
For figures with hand-painted details like the Duck Bubu bill or Snow Wing Bubu wings, be especially gentle around paint transitions. These areas are sealed but repeated aggressive cleaning can wear the clear coat over time.
Cleaning Schedule and Prevention Tips
Dust weekly if displayed open. Deep clean with damp cloth monthly or when you notice fingerprints. If your figures are inside a glass or acrylic display case, you can stretch this to dusting monthly and wet cleaning every 3-4 months.
Prevention beats cleaning every time. Handle figures by the base, not the body. Wash your hands before handling. Keep figures out of kitchens where grease particles settle on surfaces. A $15 acrylic display case from Amazon reduces cleaning frequency by 80 percent.
For Voxelyo PLA figures specifically (Duck Bubu, Snow Wing Bubu, Angel Bubu, Pink Fang Bubu), the hand-applied finish is durable but not indestructible. Treat them like you would a painted model kit — gentle and consistent beats aggressive and occasional.
