Supco MO44 Rust Buster Liquid Penetrating Oil

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

This stuff might as well be water in a bottle. It has absolutely no effect on my rust anyway.

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.

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

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

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.
