Tools You Actually Need
Soft microfiber cloth (lint-free), a natural-bristle artist brush (1-inch flat), distilled water, and isopropyl alcohol 70% for stubborn spots. That's it. Everything else — magic erasers, dish soap, acetone — risks surface damage.
Never use paper towels directly on the figure surface. They're micro-abrasive and will scuff a high-gloss finish over time.
Routine Dust Removal (Weekly or Monthly)
Use the artist brush to sweep dust from crevices — ears, the gap between head and torso, the underside of limbs. Work top-to-bottom so dislodged dust falls away.
Follow with a dry microfiber cloth over smooth surfaces. Apply zero pressure — just contact and drag. The cloth picks up electrostatically. If you press, you're grinding dust particles into the finish.
Removing Fingerprints and Smudges
Dampen a corner of microfiber with distilled water (not tap — minerals leave residue). Lightly blot the smudge. Do not rub. Follow with dry section of cloth.
For stubborn fingerprints (skin oil builds up over months), use a cotton swab barely moistened with 70% isopropyl alcohol. Test on the underside of the base first. Wipe once in one direction, let dry fully before touching again.
Cleaning 3D Printed PLA Figures
PLA is more sensitive to heat than vinyl — never use warm water or steam. Distilled water at room temperature only. The same microfiber-and-brush approach works, but be gentler around painted areas, especially on the face.
Avoid isopropyl above 70% — higher concentrations can lift hand-applied paint on 3D printed pieces. Test first on an inconspicuous area.
What Not to Use
Magic erasers (micro-abrasive, will dull finish), dish soap (residue, potential for surfactant damage to paint), acetone/nail polish remover (dissolves paint and plastic), compressed air at high PSI (can force dust into crevices and damage delicate painted features).
Hot water is a hard no for PLA figures. Above 60°C (140°F), PLA can soften and deform. This is unlikely in cleaning but worth knowing: never leave a PLA figure in a hot car either.
Preventing the Problem: Display Positioning
Enclosed display cases (IKEA Detolf, or any glass-front case) dramatically reduce cleaning frequency. A figure in a case might need cleaning twice a year; one on an open shelf needs it monthly.
Position figures away from HVAC vents, open windows, and cooking areas — airborne oil particles from cooking deposit on surfaces and are harder to remove than plain dust.
