I like to use either Meguiars or Armor All products. The Meguiars cream comes in a black, plastic bottle and you can get it at any auto parts place. The new Armor All gel comes in a clear, brown bottle. It looks like a Heinz bottle. Both are good products and I have used both. My favorite is the Armor All cream, it came in a brown, upright bottle and was a cream not a gel. I have not been able to find it anymore I have been told it was discontinued. This was the best in my opinion. If you cannot find the old Armor All cream, try the gel or the Meguiars cream. For a quick clean, try the Armor All spray in the white bottle with a brown label background or the Armor All leather wipes. For a first cleaning though, I'd suggest the cream or gel.
If you can't wait for the mailman, then go with LEXOL cleaner followed by their conditioner. If you CAN wait, then order Leatherique - it is the better of the two products in my most humble of opinions!!!!
Head for your nearest saddle or tack shop or farm supply store. Find a can of Neat's Foot Oil. DO NOT use a gel/paste product called Mink Oil in a flat tin.....you'll stick to it forever. For just plain cleaning and preservation, use saddle soap.
