I have the leather/cloth combo seats in my 2013 S Clubman and I think they're absolutely gorgeous. However, I run/work out quite a bit, and the summers are hot here - I sweat. My driver and passenger seats have developed white-ish rings. From now on I'll put towels down, but is there a product best suited for removing the current spots?

It's driving me NUTS.

 

Any over the counter fabric or carpet cleaner in a spray bottle will work fine. No need to get crazy and buy something outrageous. If your worried or concerned about damaging the fabric, start on an area of the seat that you can test and see the results. After you clean them, spray the fabric, not the leather, with scotch guard. It will help to repel any moisture in the future as well as protect from any other possible spills. Good luck and happy cleaning.
