I picked up the Gearbox Pickleball Paddle Cleaning Block to deal with scuff marks that build up on my paddle face, and it does the job well. The soft rubber material feels gentle and hasn't damaged the surface at all. It clears dirt and minor scratches quickly, and the compact size means it just lives in my bag. Works fine on the paddle surfaces I've tried. Nothing fancy, just a simple tool that keeps my paddle looking clean.
