Today I experimented with a cool product used by dairy farmers on thier milking equipment I guess, don’t know for sure, but it plays hell on rusty tools and metal. My brother Julio told me about it ( Available at Tractor Supply ) Julio used it to remove rust on his 56 Chevy two door, used it on various parts of steering and frame, so I thought I’d try it and guess what IT WORKS by gee golly. I tried on my rusty calipers through lack of use for about 6 years . I’m sure it would work on those rusty table saws out there.! I started by brushing the product on the calipers and then I dipped it in a pan full of the product. In the last picture it shows the compressor part broken in half, don’t know what caused it. It leaves a dull finish which can be buffed out on a buffing wheel or with steel wool. Oh yea, it works great on stainless steel.
