Supco MO44 Rust Buster Liquid Penetrating Oil

Very good product, it works.

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.

I like this stuff , it really works good if you have time to leave it sit overnight has saved me many times from drilling.

Excellent product. I had two very rusted screws and bolts and it only took two minutes after I squirted it on.

This stuff is amazing, way better than pb blaster and wd-40. Bought for appliance repair but it works amazingly well on automotive bolts as well.

Works great!

This is the best penetrating oil I have ever used. It almost literally works miracles. I maintain building systems and there are some rusty junkpiles that need to be serviced where I work. This stuff always does the trick especially if there is time to leave it to work over night.

This stuff is great!

Helped get a stuck shower-head loose. Good to keep a bottle in your toolbox.
