Regular washing is essential if a car is to hold its value. There are two main options when it comes to keeping your car clean: either washing it by hand or taking it to the car wash. There are pros and cons to both alternatives, as summarized in the table below.
Alongside the technique, the choice of a good car shampoo is a key factor in the success of handwashing. Shampoos can be split into two main categories: cleaning shampoos with high cleaning power, on the one hand, and care shampoos with waxes and silicones. You should consider the following points when selecting the right car shampoo:
- Cleaning Shampoo:
A cleaning shampoo boasts high cleaning power and does not contain any care products. It is usually highly alkaline or acidic (not pH-neutral). After washing, the result is a dull finish with little sheen and no beading effect.
- Care Shampoo:
Care shampoos offer varying degrees of cleaning power and contain care waxes or silicones (drying aids). After washing, the result is a glossy finish. A care shampoo often features a beading effect and is usually pH-neutral.
A shampoo is pH-neutral if it has a pH number of 7. If the value is lower, it is acidic; if the value is higher, it is alkaline. Non-pH-neutral shampoos may attack existing seals and the paint surface, making the finish dull.
We recommend using a pH-neutral care shampoo. The car shampoo should also boast good foam formation and a pleasant odor (e.g. MZ Wash).
