Most leather wipes contain weak products that have no real cleaning ability on leather and they generally just move the dirt around without removing it. You would need to use a lot of wipes to get any useful cleaning done although they do have their place for occassional wiping up of spillages etc. Fat better to use a specifically formulated maintenance product with a cloth that will remove the dirt - more economical and environmentally friendly as wipes only add to the landfill.
Some wipes contain products that will if not cleaned off the surface will leave residues that attract more dirt so defeating the object.
Hope this helps
