Hey guys,

Tried to search something up but could only come up with stuff that regarded the first clean.

Anyways, I've doing around 6-7 casts on my Lee 2C molds and on the inside you can see little brown tinted lead or maybe just dirt. Anyways its too hard to just wipe off with a towel and don't want to scrape at it if I don't need to.

Any type of brass wool or something that I can use on Al molds?

Thanks in advance, sorry if asked prior.
