Supco MO44 Rust Buster Liquid Penetrating Oil

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

This stuff is great!

This stuff really worked like a charm!

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.

It worked, on one bolt that was stuck, didnt work on a 2nd stuck bolt.

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

Very good product, it works.

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.

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

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