Our original brushes changed the game by offering a comfortable grip unlike anything else on the market. With the TriGrip brush line, we've further refined our design and added a rubberized triangular grip area for maximum comfort. These Ultra-Soft brushes are specifically designed for light-duty cleaning on scratch-prone automotive surfaces, such as "Piano black" interior panels found in many modern cars They also work great for instrument and infotainment panel dusting and cleaning as well as detailing around badges and emblems where boar's hair may mar the surface.
