I can recall it helping unstick the rusted nuts and bolts on my old Huffy bicycle, loosen the nuts and bolts on my first motorcycle, and even help unstick the rusted nuts on my first vintage chevy pickup truck exhaust pipes. Sure there are plenty of others out there that say they are good, but this company's longevity proves they are the real deal and can be trusted with your prized possessions.

Ive used this for about 25 years, and its the best penetrating oil on the market. It doesn't work instantly, But it works almost every time. If a bolt is frozen, just soak it in this and wait. Preferably overnight, but a couple of hours usually does the trick.Ive used it on everything from frozen suspension bolts, to locked up engines with stuck pistons. It even works great for cleaning firearms. Only negative is that it makes a crappy lubricating oil, but ive got other stuff for that.
