Anyone aware of any recommended products/procedures that are specific to the R3 seats? I'm mainly interested in preserving the leather parts, but it'd be nice to do a decent job cleaning the cloth parts as well.

 

Not specifically for the R3, but I use '303'.

It's like magic on the rubber and plastic bits, and is recommended for leather too.

 

I use a product that I received for my leather couch from Leather Masters (Uniters). Is is a 2 step product (1) Leather soft cleaner then (2) Leather protection cream. Works great on the couch and two cars with leather seats. Came with the couch at a furniture store in Cleveland, OH.
