All of us have to deal with rust on our tools. I have discovered
something great for this problem. It comes from the woodworking
industry and I originally purchased it for my table saw.
It is called Top Saver by Empire Manufacturing, empiremfg.com, and I
imagine that it is available at most woodworking places including
the woodworking catalog companies as well.
This product is wonderful. It, and some scotch brite will completely
remove the rust on your hammers, stakes, mandrels, bezel blocks, etc.
Then you apply a second coat for protection. Give it a try.
No I am not a representative or affiliated with the company.
Also a trick some of us use, we that come from wet climates, is after
you pickle or wash anything you are working on is to heat it somewhat
before you start to work on it again. This drives off that last bit
of water that often remains even when you think it is dry.
Hopes this helps with those rusty winter blues.
