How to clean leather couches
If it is real leather, purchase a good leather cleaner to clean it. Once you have cleaned it, make sure you use a leather conditioner to keep the leather moisturized and supple. I use the Lexol brand leather cleaner and conditioner on all leather things, from car seats to furniture to boots with good results. They also have a great vinyl cleaner and conditioner. I find it in automotive departments usually, but always find it at local auto parts stores. I hope this works for you, Rhonda!
Saddle soap and leather conditioner.
Hometalks How to Clean Your Leather Couch link might be informative. I hope it helps address your concerns.
Good link from Vinmar.
We love leather wipes. You can get them at Home Depot, Walmart, grocery stores. Is this general cleaning or deep stains like pen marks etc.?
