If you prefer Meguirs then get their cleaner wax at any parts store and machine apply it...BOOM your done. Cheap machines do little work though. Buy a good one if you want to keep them looking good. A Porter Cable 7424 would be perfect for your situation as you want results without going broke
I am cleaning a 2003 King Ranch in a few days. It has aniline leather seats. Anyone have experience cleaning and conditioning these types of seats? Products specific to this type leather? They have many stains.
