I wrote an article in my blog about cleaning shoes, just a few days ago. Basically there are 3 types of cleaners for use on leather shoes: 1) High solvent strippers like RenoMat, 2) Glycerin based cleaners like saddle soap and Lexol Leather Cleaner, and 3) Mild solvent cleaners combined with conditioners like Renovateur and my GlenKaren Cleaner/Conditioner. Each has a somewhat different purpose, and each are applied/removed differently. For example: You want to remove all of the RenoMat from your shoe once you are done cleaning/stripping the shoe, but you would wipe it off with a cloth, not wash it off with water and a sponge. You want to remove all of the glycerin from your shoes once you are done cleaning, but you would do it with a clean water rinse using a sponge/cloth. For a cleaner/conditioner you want to wipe off the excess with a cloth, but let the majority soak into the leather before brushing with a shoe brush.
