Can you use sandpaper on copper?
Keeping this in view, can I use sandpaper for copper pipes?
But fine steel wool or regular 120-grit sandpaper will do in a pinch. Clean the inside of copper pipe fittings with the emery cloth too; simply roll a short piece around a finger and reach inside.
- Add a small amount of water to baking soda until it makes a paste.
- Wipe the item with a clean, wet cloth to rinse off the baking soda.
- Dip a soft cloth in lemon juice if scratches remain.
- Dampen your fingers, then dip them into some salt.
Keeping this in view, can you sand copper?
First, what you would want to do is, get some 360, 600, and 1200 grit sand paper. I would go for some 2000 grit sand paper too, but it isn't very necessary. Then take the lowest grit sandpaper, (320) and wet-sand the copper (I haven't tried JTfettig's 25% soap 75% water mixture before, but it should work).
Sandpaper readily scratches metal, and the scratch marks aren't as easy to remove as they are from wood. When sanding metal to remove rust or to deburr an edge, therefore, you shouldn't use sandpaper with a grit coarser than 220, and, if possible, you should use an even finer one, such as 320.
