Supco MO44 Rust Buster Liquid Penetrating Oil

Great product. Used it on the center assembly of our 11 year old washing machine. Unfortunately the locking nut had fused to the assembly below it. The Rust Buster liquid removed all the surface rust, but after six hours of pounding the wrench in the correct direction for this reverse-threaded nut, it would not separate, so I hacksawed it off. After that the repair was easy (though we never did fix the leak we were trying to get rid of, and wound up buying a new washer). At the end I was disappointed but realized the rust buster wasnt the problem - it actually made the whole assembly clean and rust free.

This is awesome, cuts through rust esily

Very good product, it works.

Specifically purchased to loosen a frozen screw in a handplane. After 8 or 10 tries I decided I was wasting my time. Took the plane outside and torched the snot out of the frozen screw which surrendered instantly.

Have used this product for years. Amazing the way it desolves rust.

This worked great getting some rust off of one of my magazines that rusted.

If there is any liquid that will work, it is this one! Must have very small molecules.

Bottle is half, of the liquid and looks used , you cannot return this , so be aware if you buy it

You can buy in the aerosol spray, but I find this works better as s soaker when you need to use judicially.

Had a rusted hose for a washing machine that I had to get off. It was in a very awkward spot in an old house. Nothing else was working. 15 min after applying and heating with a hair dryer the hose came right off!
