MR BLUE CLEAN Expert opinion

The Blue Clean 491 high pressure washer can help you clean your car quickly and thoroughly. For best results, we suggest you follow some simple guidelines. For example, before applying the detergent, initially spray the body of the car with a jet of water to remove coarse dirt such as mud and debris. Then apply the detergent directly from the high pressure washer’s practical 1.4 litre built-in tank, using a product that is suitable for this type of instrument and specific for the surface to be washed. We also recommend that you choose a shady place to wash your car, since excessive heat from the sun can cause the soap to dry quickly, creating spots and imperfections.
