The key is to take about 20-30 seconds and blast the shit out of the brush before using it; and make sure that you have thoroughly rinsed the car to remove all the large particles. Then when you blast the brush, I guarantee that there won’t be any particles left in it. Same here. Sometimes there is shit on your car that just won’t come off with the pressure washer. --- _[View the full topic](https://forums.speedlife.net/t/zr1-fail/252685)._
