After removing a sticker from frame I have layer of glue residue left that can't be removed even when using brake cleaner or WD-40. Only scrubbing for 10 minutes nonstop removes it. Is there an easier way to get rid of that residue without damaging the paint job?
Heat guns and even hair driers are known as capable of removing stickers. Of course, this would heat the surface. Likely not a problem for a metal frame but generally think where are you applying.
De-solv-it removes anything, I had nail polish on my couch from my niece, only desolvit saved the day, I use it on every stain with little scrubbing required :)
