The basis for all car detailing starts with the wash, so it’s essential to get the basics right. The first thing to look out for when choosing a car wash product is pH neutral soaps. pH neutrality means the product has neither acid or alkaline. If acid or alkaline are present in your water or your soaps, this can affect the quality of your paint - meaning the best car wash products are pH neutral. All MFD car wash products have an pH range of 6.6–7.3, meaning they are safe to use on all paintwork.
