Just one 400ml bottle of Bathe Essence makes 80 buckets of effective car shampoo. Not only does it produce no-fuss results, but it's one of the most cost-effective shampoos on the market. We probably don't have to say much more than that, but this product deserves a proper introduction.
Q2M Essence contains no waxes or silicones, and in fact no fragrance; it was purely chemically engineered to provide an incredibly slick surface while washing and to rinse away without leaving anything behind. It's why we use this for maintenance washes at Parks Detailing; it helps us maintain clients' freshly polished vehicles without affecting the protection we've applied or requiring extensive effort to rinse off.
Many other car shampoos on the market contain waxes or silicone agents which leave behind residue, or contain unnecessary fragrance additives that can also affect the properties of underlying waxes and coatings. Put simply, this is a zero-BS car shampoo.
5-10ml (less than a ¼ of ounce) per wash is all that is needed to provide effective cleaning power.
