Hello, Rich - We are sorry that this cleaning kit did not meet your expectations! The medium bristle brush that comes with this kit is for general-purpose cleaning. And if you are using it for that purpose and are still not pleased with its performance, then please email us directly at Reviews@RYOBItools.com. However, if you need something for more heavy-duty cleaning applications, then we recommend our Hard Bristle Brush Cleaning Kit (Model # A95HBK1). Or, you may also want to consider our Abrasive Bristle Brush Cleaning Kit with Extension (Model # A95GCK1) which is great for material removal applications. You can find both these options by simply searching for their model numbers on the Home Depot website or copy/paste/enter the link(s) below into your browser. We hope this helps! And thank you for the review!
