I use Scrubbing Bubbles on my DE's periodically. However, I was reading the back of the can and it says it's not recommended for brass. So, is it safe for vintage DE's?
What's good to remove residual rust from around the posts on a single ring? Will soap and water do the trick if I scrub with a toothbrush?
And sometimes a little baking soda.I ain't a big fan of Scrubbing Bubble, I prefer hot water and soap.
