How to remove paint from your bike frame:
There are a few things you’ll need when removing paint from your frame: paint remover, paintbrush, some steel wool and/or some sandpaper.
The first thing you want to do is get a rag and maybe some water. Wipe down the frame and make sure the surface area is nice and clean.
Once the bike is clean, fill a small container with the paint remover. Use the brush to spread the paint remover over the frame. You don’t need to make sure it soaks in or anything, but just layer it on top. Do one coat of this all over the frame. Then leave the paint remover on the bike for 5-10 minutes and paint should begin to peel off a tiny bit. After about 10 minutes, apply another coat of paint remover and wait for about 40 minutes.
Once the 40 minutes is up, use a tool that will allow you to scrape the paint off of the bike. A number of tools will be suitable for this. When you have gotten down to the bare metal, use sandpaper and steel wool to get any little leftover paint off of the bike. Sanding will definitely take awhile so be prepared.
That’s how to remove paint from a frame!
