I have a ton of taps that I got from the son of a retired machinist. Honestly it looks like the guy never used the same tap twice and just kept tossing them into a bucket. Got taps from itty bitty 4-40 stuff all the way to 1.5 inch. Some are standard some are custom Like a 1 5/32 24 pitch one that is still in the plastic coating. Some however are surface rusted a bit and I would like to clean them up in bulk rather than one by one. Any ideas for bulk cleaning a bunch of taps and end mills. I got a ton of them too.
