Nowadays, the car or truck can be washed with confidence in a modern car wash. New generations of brushes, detailed pre-wash technology and high-tech resources have fortunately ensured this.
However, we do see another problem lurking lately: tarnished aluminum.
Cars with beautiful shiny trims, sport rims, roof moldings, emblems and entry strips. But even fuel tanks, side shields and trim on trucks to entire tank cars are (often) made of fragile aluminum or other light metals. When the wrong products are used, aluminum dulls and can discolor, which is then difficult to repair. How does this happen and what can you do about it?
1. Aluminum alloys are becoming more fragile
Due to the intrinsic motivation of car and truck manufacturers to further reduce weight and the scarcity of raw materials, aluminum parts are becoming lighter and lighter. However, this makes aluminum parts more vulnerable to external factors.
2. Detergent manufacturers save on ingredients
Strongly alkaline pre-cleaners and truck cleaners with high lye contents are often the cause of this tarnish in the car & truck wash. However, the tarnish can be eliminated by smart formulation and adding additional aluminum protective ingredients. However, due to scarcity, these raw materials have become very expensive and we see that many detergent manufacturers are currently cutting back on this.
3. Heat and drying
Aluminum but also lacquers are extra sensitive to heat. It is therefore always advisable to cool the paint first, for example with clean water, before you start washing. In addition, an agent should never be allowed to dry out, as this can cause (irreparable) damage.
Custom advice
Ironically, most explanations seem to have to do (partly) with raw material scarcity. So it is important to make the right choices here. Our team has handy tools to track down products that damage aluminum. Looking for honest advice? Then contact us.
