Clean your leather upholstery naturally!!

Mix one part white vinegar with two parts linseed oil (also known as flax seed oil), shake well, and apply to the leather using a soft cloth. Work in a circular motion, covering the entire surface. Rub in thoroughly, let it sit for about 10 minutes, then buff with a soft cloth to bring a shine to the leather surface.

Also you can remove dark stains from light-colored leather upholstery by mixing a paste of one part lemon juice with one part cream of tartar. Rub the paste on the stain and leave in place for about 10 minutes. Apply another layer of the paste, work it in, then remove with either a damp sponge or a damp sponge topped with moisturizing soap like Dove (my favorite).
