P&S Interior Cleaner and a brush. Sometimes I’ve used Wolfgang Leather Cleaner. I then use 303 Protectant and Ultimate Fast Finish for coated leather. Some leather balms/conditioners are formulated for coated leather, they just don’t advertise it because 99% of people have no idea about coated leather. Meguiars has a write up in Autogeek.net on their ultimate leather balm and its usage on coated leather. I’ve used it many times for testing purposes with no ill effects.
a great protectant for coated leather is Meguiars Ultimate Fast finish. Designed for paint obviously, but it’s formulation works great with coated leather. Give it a shot.
