FAQ
What’s the safest paint stripper for DIY use?
Citristrip citrus-based gel is safest for indoor DIY use. Slower but no toxic fumes.
Do paint strippers damage metal?
No. Modern strippers only remove paint. But leaving stripper on too long can etch aluminum and some plated surfaces.
How long does chemical paint stripping take?
MC-based: 15-30 minutes. NMP-based: 30-90 minutes. Citrus/water-based: 2-24 hours.
Can I use paint stripper on plastics?
Only water-based strippers are safe on plastics. MC and NMP strippers will melt or discolor plastic parts.
Do I need to sand after using paint stripper?
Yes. Even after full paint removal, the metal needs 220-grit sanding for adhesion before priming.
How to dispose of used paint stripper?
As hazardous waste. Most municipalities have designated household hazardous waste facilities. Never pour down drains or into soil.
