Mouse Milk Penetrating Oil delivers unmatched performance when it comes to freeing rusted or seized parts. Known as "Muscle in a Hustle," this powerful yellow formula rapidly penetrates threads, fittings, and tight spaces—dissolving rust and corrosion while providing lasting lubrication. Whether you're working on aircraft engines, automotive components, or precision tools, Mouse Milk is the go-to choice for reliable maintenance results.
Thanks to its unique creeping ability, Mouse Milk flows into microscopic gaps where other lubricants fail, making it an excellent choice for engine tear-downs, heat risers, smog valves, frozen valves, and more. It also functions as an effective cutting and tapping fluid during machining operations.
I worked as an aircraft mechanic for many years and was introduced to this product in my junior years and never looked back.
this thing is amazing on the most rusted out bolt treads, it some how creeps in and loosens without applying any heat.
I am retired now and since then I have tried many other name brands to compare on different projects but nothing comes close to Mouse Milk!
Highly Recommended!!.

Mouse Milk is fantastic.
Works where others can't. A little goes a long way and it can be used over and over. Shipping is fast and professional. 5 easy stars!

Stuff works
When working as a contractor on US Air Force aircraft overseas we would rebuild small engines that were turbo-charged. Each time the turbo bolts would be frozen in place. I'd witnessed countless tools destroyed; sockets, ratchets, extension, you name it. But after a few drops of Mouse Milk we would break for chow, come back and wallah, broke free with minimal effort. I keep this in my garage and bought a bottle for my dad and brother. We've all had had successful results.

I have Mouse milk at each house. If you have any screw stuck this will get it loose every time. Just give it time to work. I had take apart a picnic table that had rusted screws. Worked on every one of them. Used on a door handle that was corroder, worked again. Buy it, you will love it. My son is an airline mechanic, that is how I heard about Mouse Milk. Cute name also. Tell your friends!!
