The SideWash brushes must be periodically cleaned with specific chemical products (CLEANING LINE by Favagrossa), following recommended modalities and doses. In fact, regular use of low quality products can cause irreparable damages to the brushes, deforming them up to make them useless. In any case, the brushes should be plentifully rinsed in lukewarm water (no high pressure) before and after using chemical products for cleaning them.
