Reliable is the best cleaner I have ever seen. Wanted to pass this story along to you guys. Yesterday I was changing the engine oil in my diesel tractor. I accidentally got some oil on the sleeve of a new coat that I had just gotten. (You know, the BLACK oil from a diesel engine.) I wiped the bulk off andgrabbed a bottle of Reliable. Sprayed some on the sleeve, let it soak a few seconds, rubbed it together and rinsed it with cold water. All the oil came out of that sleeve.Not just an RV cleaner!!
