Liquid Wrench Penetrating Oil 11 oz Aerosol Can - 12 Pack for Rust Removal, Loosening Bolts & Mechanical Maintenance | Ideal for Automotive, Industrial & Home Repair

I began using this as a kid to free rusty bike bolts, then on to minibikes, motorcycles, cars, trucks, industrial and heavy equipment. It's not for cutting fluid or as a lubricant, but you can use it for those jobs in a pinch. It's for freeing stuck bolts; just put this stuff on the stuck threads, let it sink in, put it on again and crank 'em loose.Some of the other products work better than nothing at all, but for critical jobs, this gets your parts off easier.
