Supco MO44 Rust Buster Liquid Penetrating Oil

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.

penetrating.....

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

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.

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

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

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

Very good product, it works.

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