I tried using it to free gunged-up door levers on our car when we were in Lesotho. It turned the sandy/greasy mix that was making them stiff into a solid lump!!! So I then had to do what I should have done in the first place: take them apart and grease them properly. They worked fine after that! Having said all that I do make generous use of it round the house: door hinges, clock mechanisms and the noisy fan on my R*s*P*.
