I've been using Swissvax products for a while now. After getting the M5, I knew I was going to have to deep clean the interior. This is where the Swissvax leather care system comes in.
This is the final step in the leather care process, after cleaning with either Swissvax Leather Cleaner or Leather Cleaner Forte. I apply it with a foam block and then wipe off any excess with a coating towel and it leaves the leather nice and supple without a greasy residue.
It comes in two sizes: 250ml and 470ml.
