If you like a little to go a long way, Q2M Bathe Essence is the wash soap to keep with your car washing supplies. Highly concentrated car shampoo would be an understatement with a dilution ratio of 1:2000. 5 ml of product is perfect for about 4 gallons of water give 80 washes out of a 400ml bottle. Impressive cleaning power and the ability to remove dirt, grime and light organic contamination are combined with fantastic slickness and high foam in Q2M Bathe Essence.
