Sand the chrome with the 220-grit sandpaper. The rough sandpaper should remove the majority of the chrome. Move up to the 300-grit sandpaper and then the 1,200-grit sandpaper, applying more polish as you continue sanding. Sand the surface until all of the chrome is stripped off.
Can you use sandpaper on Chrome?
The best way to paint over chrome is sand it with about 120 grit sandpaper. You really want to get scratches into the chrome. Then use a “self etching” primer to prime over it. I would put 2-3 coats then sand with 400 grit and paint.
How do I make Chrome dull?
To make shiny chrome surfaces dull, scrape the chrome with a scouring pad or some very fine sandpaper. Continue scraping until the chrome is as dull as you like. For smaller chrome items that can be detached, try submerging them in a solution of muriatic acid.
