RCP's 20" Pot Brush Blue with Stiff Bristle is a must-have for washing and prepping a vehicle, combining a long reach with the scrubbing power of stiff bristles. Its heavy duty construction ensures this brush will last for a long time, making it a professional choice for the dedicated auto detailer. We recommend using it with plenty of soapy car wash solution to break down stubborn dirt and grime across large panels and hard-to-reach areas. The generous 20" length lets you cover wide surfaces with ease while the stiff bristles power through tough buildup. This brush paired with a quality wash solution and a plush drying towel will take your detailing experience to the next level.
