Yes the leather shammys are great and do a good job!
But You don't use cleaners with the leather shammy's! The chemicals can damage the fibers and also remove the natural oils that are in the leather.
Spinning the ball on a towel is like a gunfighter twirling a gun on his finger. It's showy, but not a effective way to use it.
For the most effective cleaning you should wipe the ball not spin it.
Also Leather towel/pads need to be clean to be effective and will make the pad last longer. Leather shammy pads are made of leather. Treat it more like a car chamois and don't machine wash or tumble dry it.
Also I suggest not using dish soap, they can contain degreasers that can strip away the natural oils in the leather. use a natural soap like a bar of pure soap that you would wash your hands with or a good car wash shampoo.
Remember the Shammy Pad is made of leather
How to Clean and Care for your Genesis Pure Pad.
If you begin to notice your Pure Padâ„¢ is not as effective as it once was, then it's time for a cleaning. Luckily, this is an easy task. Simply wash using some mild soap in warm to hot water, then gently agitate the surface with a brush. (Tip: Using water as hot as you can comfortably and safely handle helps to release extreme amounts of oil).
Once done, rinse your pad thoroughly under warm water, wring out, then lay flat to dry. Once dry, you can use a bristle brush to bring the knap back to an "as new" state, if needed.
