We use 3 different types of brushes. One is a horse hair brush. We use that for VERY high ends, or for old worn leather that is already showing some suede. We use one similar to that brush (although it doesn't get as much use), but I think would be fine for most anyone. And then we use one that is much more aggressive that I get from target in the automotive section. It is rectangular and about 3-4 inches long and about 2.5 inches wide. I've found that you can pay 3 times as much elsewhere but that brush is perfect. It fits right in the palm of your hand so there is no miscues and it comes with a hook for hanging which is a must for us so they don't go on the ground. Like that last post said, agitate do not scrub. And don't buy your leather cleaner from target. Get the good stuff. And if you are not the only one touching the brushes be sure to label them as LEATHER ONLY. That way nobody ever puts some degreaser or something on them and causes a big mess.
