Perfecar's Leather Cleaner is best used right before applying our Leather Conditioner. It will remove all of the nasty oil, stains, french fries, and contaminants that rub off of your clothes and merchandise that touch your leather. Leather is a tricky product, and good leather is very difficult to properly clean with store bought cleaners that are really made for pleather. Our cleaners contain no silicone, no petroleum, no solvents and no glossing agents. It's water based and will get the bad stuff out just in time for the Leather Conditioner to work its magic on the restoration and maintenance side.
