A mechanic puts Liquid Wrench, PB Blaster, Kroil, and more to the test. Surprising results! https://www.youtube.com/watch?v=xUEob2oAKVs Hope this helps. **Q: Which bottle does it come in? When I put it in my cart, the photo changes to a different bottle. Is it a squeeze bottle?** A: Yes, it comes in a squeeze bottle of 8 ounce size. However, you may wish to apply this super lubricant to small moving parts. In which case the large squeeze nozzle will pour way more than is needed to lubricate a small area. Consider getting the Titan Precision Oiler 15200 on Amazon. This will deliver mouse milk or any other fine lubricant to small parts such as a clock, or oiling parts of a gun. With a precision oiler, you can use for many more areas and situations. This is a fantastic lubricant. **Q: Can Mouse Oil be used as regular oil/grease to lube non-rusty large or small components such as motor bearings, gear shafts or gear teeth?** A: mouse milk is great for non-rusted items, the penetrating value is really outstanding, the term to fix the squeak is great. I have used it on motor bearings and guns, really good stuff. BigG **Q: can this be used on old sewing machines that are gunked up with old oils?** A: Mouse milk is a very effective penetrating oil for loosening stuck and corroded parts and hardware on aircraft and automotive exhaust systems. I’m sure it will work on a sewing machine, however it would be expensive to use as a cleaning solvent.. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Used It Daily in Aviation Repair *by D***D on August 20, 2025* Best stuff anywhere.
