ALEXANDRITE is a car shampoo containing organic acids, which is a perfect choice for several reasons. By itself, it removes mineral dirt, limescale and traces of acid rain from the bodywork. It can also be safely used to wash ceramic coating, sealant or wax maintenance. After an alkaline pre-wash, it helps to neutralize the surface.
For hand washing in a bucket, 25-50 ml is needed for 10 liters of water, so it is extremely economical.
