Cleaning taps & dies that have surface rust

<< < (2/2)

a few month ago I tried the electrolysis method and it worked ok and messy, used an 8 am manual charger. messy and lots of work used sodium carbonate from a pool supply store.
I picked up a large handful of rust actually a bunch of rusty tooling for lathe, this time I put the parts in an old slow cooker my wife gave me and put in evaporust, my first time using it. In about 1 hr. all the rust was gone with a little rubbing. I then washed them and sprayed them with there rust preventer I also purchase. I am impressed with the product.  My next venture I will use vinegar straight and do a comparison. If you have a very large item maybe electrolysis may be the hot ticket. Have yet to get molasses and try it. SO FOR SMALL ITEMS EVAPORUST WILL BE YOUR FRIEND.  it can be returned to the bottle and reused.

I get amazing results with cider vinegar, but it is actually my home made cider that went wrong, don't go to morrisons, it will cost you a fortune!

I have a permanently set up electrolysis bath so anything rusty gets put in for a few hours. Works like magic. :)

Yes, it works very well and doesn't etch the surface of the steel like acid does.  :thumbup:
