Armorall cleaning wipes, then meguiars gold class wipes, then a 3 in 1 leather clean protect conditioner.. do all 3 steps and find new life in that old dead hide you sit on as you ride!
Yes, haha I am anal. But.. when you sit in my car and ask yourself "holy **** is this a 2006 model?!?" you'll see why I go through all this trouble,
Estimated lether treatment time if you are a freekin' OCD maniac like me and try to make things like new.. well it took me about 20 mins per seat.
It's well worth it, good luck!
