Best way to remove brass corrosion
I bought 3 brass cachepots at an estate sale. The style looks middle eastern to me, with a lot of detailed stamping and repousse. There is corrosion on the bottom half that looks like small spots of rust. I know brass can't rust: it just looks like rust. I'm used to corrosion on brass looking black or greenish.
I've used Brasso before, and Penny Bright, but are these the best products to use?
Also: they have been polished before, and there is a lot of white residue trapped in the detailing, especially in the cross-hatched areas. I have a huge old tray in the basement (for the last 20 years) with embedded white stuff I have never been able to get out. I'd need a needle and a few months to get it out of all the engraved lines. What I think I remember about using Brasso before (admittedly itÃ¯Â¿Â½s been a while), was finding it very hard to get out of incised details. How would I get this out? THanks!
See the red spots?
