Supco MO44 Rust Buster Liquid Penetrating Oil

penetrating.....

Unstuck a rusted bolt on the boat engine that most said could not be done.

I used this to loosen some bike wheel spokes that resisted truing. It works well, well especially if you let it sit for a little time. The product is very thin, as a penetrating oil should be, and really gets into the threads (and everywhere else). The cap design is flimsy, and it doesnt fit well. The company should probably spend another 5 cents and get a cap that fits snugly.

Works great!

This stuff is great!

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!

Ive used this several times already and theres no question it is superior to other penetrating oils.

Assume this would have worked on an application where the oil could run downhill. My application was more horizontal so no much of the penetrating oil soaked into the rusted threads.

But rust buster you could ever invest in.

Works just like PB Blaster, maybe a tiny bit better. I like the long straw it has to get into small crevices.
