Definitely, you should try and wash at least once a week. The reason being the road contains lots of salt (and other harmful pollutants) and you defo dont want salt near your vehicle, thats why you should never use washing up liquid over a car shampoo because washing up liquid actaully contains salts and when using car wash shampoo gets rid of salts!!.Well i often rely on a good downpour. I use mine often and wash ever 3 months or so.
Are there any disadvantages to not cleaning more often?
