Re: Walnut and comet cleanser in tumbler
The SS pins sure do make brass look like new, inside and out. I bought 10 pounds of pins a couple of years ago and I've used them many times. The drawback is the time required to separate pins, brass, and water. So, I decided to only use the pins when I get some really stained brass or tarnished brass. Otherwise I just use cob and NuFinish polish.
The SS pins are expensive, but they never wear out, and never need replacing. Buy once, cry once, as they say.
