Also what grade of walnut shell is a good size for brass please? Thanks How long's a piece of string? I would say when there's a build up of dust and /or it doesn't seem to polish as quickly. It's cheap enough to chuck and replace (unless you buy shooting branded stuff at x1000% what it should cost). I think my walnut shell is 12/20 mesh, I bought a 20kg sack from a blast cleaning supplier 6 years ago and I still have more than half left! I put a tiny dash of jeweller's rouge in the media, I like the added fine polish. Quote Link to comment Share on other sites More sharing options...
