Penetrating Oil

Had an old WW2 rifle oiling flask that was rusted shut. Threw a couple drops of this on it….30 seconds later, light help from a small pair of pliers got it open. Mouse Milk tore right through that rust. I’m impressed.

Can't be beat.

I really liked this product. I bought it to make a ferrocell, and it worked perfectly. While there’s nothing visually extraordinary about it, I tested it on two rusted bolts in the same general location. I applied WD-40 to one and Mouse Milk to the other. Surprisingly, the bolt treated with Mouse Milk was about 10–25% easier to remove. I still have some left, and it continues to work great!The only downside is that you cant spray it on like with WD-40!

15 years in the aircraft mechanic business here,all i can say this is one of the best penetrating oils out there period.you can't go wrong with this stuff.great buy and highly recommended.

if you need a great penetration oil for delicate items this is it!

The best penetrating oil we have found. Always great service from Pilots HQ.

Found this product watching a random you-tuber video about a Piper plane rescue after a wheels up landing. I'm a retired Boomer, worked Line Service weekends and a couple of summers in college at a small FBO, early 80's, and I never heard of this until now. Works as advertised, easily helped break loose a stuck brake bleeder screw immediately on my Triumph Bonneville with out any drama/damage. Only slight issue - was delivered with the cap on just snug tight, given how thin and great this stuff is, about 1/2 once seeped by the threads and into the bag.

I was rebuiding the engine on my truck and dealing with several rusted-on parts and fasteners. This worked where PB Blaster, WD 40 and Liquid Wrench didn't. I also have an old snow blowers whose engine seized up. I took out the spark, poured some in the chamber and a few minutes later, I was able to easily crank it and salvage the engine. I would highly recommend this!
