I just bought a 4 year old car privately with cream leather interior. The previous owner cleaned the car before the sale but the cream leather and especially the cream seat belts are still a bit on the grubby side. The leather should be easy enough to clean but I am not sure about the seat belts. Anyone have recommendations for the best products to bring them up like new. I cannot really afford a full professional valet service. Willing to apply plenty of elbow grease.
