Supco MO44 Rust Buster Liquid Penetrating Oil

My husband wont buy any other brand, he swears this is the best on the market!

I really liked this product, after I used on old rusty screw they just were like new. Tight them up as much easier

Used it for some gun cleaning for some old rifles. Worked well but left some discoloration to the metal, wouldnt say for sure it was due to this product but just a heads up.

I found a bottle of this sitting on an old boiler that I bought out of a house. I decided to use it on the corroded pipe fittings. Every one broke loose and I have been using this stuff ever since. Works best if you can tap or impact the joint after application. Does have a tendency to evaporate easily even when properly capped. Best to store in a secondary sealed container to minimize evaporation.

I’ve always kept a bottle of this in the garage, last purchase the packaging leaked about half a bottle, but it does what it says, sometimes just need to let us set for longer.

Works like a charm on brass bushings and leaves them slightly lubricated without the chance of any build-up to occur like how it does with 3-in-1 oil

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!

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 product didnt work for my situation. I went by the instructions and it didnt work.

Nothing
