He brought the microfiber polishing cloth. The cleaning dough to Germany. Along the way, he developed his own products to preserve vehicle paint. In an interview, he reveals the most important care tips.
What do many motorists do wrong when caring for their vehicles??
Many drivers leave dirt on the paint too long. All unusual contamination such as bird droppings, tree resins or industrial deposits must be removed immediately, so every hour counts. Because they first attack the preservation of the paint and then the paint and can burn into the paint in strong sunlight. Then only an elaborate treatment, such as polishing followed by sealing, can help.
Is that bad?
With each polish I remove substance of the varnish even with fine-grained means. With every polishing the varnish layer and thus the UV protection is reduced. Color depth is reduced and color pigments fade if too much paint is removed. It is therefore better to protect the paint with a good sealant and wash the car regularly. Most drivers protect the paint too little and polish too much. This will only unnecessarily reduce the paint film thickness.
How to care for your car?
Classically by hand washing, with two buckets of lukewarm water. In the one is a mild car wash shampoo. In the other clear water. There I rinse out my car wash tools, then wring them out to take up fresh shampoo water again. Otherwise the dirt remains in the foam and sponge, so that it later creates scratches on the paintwork.
Then I wash my car from top to bottom. Section by section, i.E. First the roof, then the hood, then the trunk and then the sides, but only halay at first. Because the lower sides are usually heavily soiled by brake wear, tire wear and coarser articles, I use a different washing tool for that, whether it's a sponge or a wash mitt. Otherwise I rub the road abrasion on the varnish, which in turn results in fine scratches. After washing, I clean my washing tool in advance in the hand wash basin with a special detergent under running water. Thereby I remove already most dirt particles.
What mistakes do many drivers make when washing their cars??
First, they forget to regularly clean the sponges and wash gloves. A thorough wash is important because dirt residues in the washing tool produce the most marks and scratches on the paintwork. Afterwards they can only be removed by polishing, which in turn wears off the varnish. A special cleaning clay absorbs particles on the surface so that they do not later scratch the paint like grease gel grains. This is crucial for further steps such as polishing or preservation.
Often car drivers do not consider the exposure time of the chemistry. If the prewash is left on the paint too long, burns can occur. Rubber seals are also attacked by standing too long, anodized parts can become corroded. This often happens in summer, when there are long queues in front of the car wash. Drivers should therefore make sure that they enter the car wash quickly after the prewash.
And with a hand wash in a wash box?
Here, too, drivers should pay attention to the soaking time of the prewash, as well as the correct dosage of car shampoo. A high dosage can attack rubbers. Attacking plastics. It is important to rinse after washing so that dirt and shampoo residues do not leave streaks.
On very hot days, the car should be cooled down before washing, so that the detergent does not burn on the hot paint. This can be achieved by parking the car in the shade or cooling it with clear water in the wash box beforehand. Because every cleaning process has four parameters: Chemistry, temperature, contact time and tool. If the temperature of the sheet metal is too high during cleaning, washing chemicals can damage the paintwork.
Are there special rules for owners of convertibles?
Before convertible owners take their car to a car wash, they should find out whether there is a special convertible wash program available. This is important, because otherwise the rollers and washer nozzles have too much effect on the fabric roof and damage it. Also, not all fabric roofs tolerate the cleaning chemicals for car paints. In case of a hand wash in the box, the top should be washed with a special. Gentle detergent to be cleaned without much pressure. Otherwise the impregnation is quickly reduced and the fabric structure suffers.
How often should owners wash their vehicle?
I can't give a general answer, because it depends on the annual mileage of the car and the dirtiness of the car surface. From 180 km/h, small stone chips increasingly destroy the paint surface. For a city car that travels about 12,000 kilometers a year, I recommend a weekly car wash – and an immediate one after exceptional soiling. It sounds like a lot, but it protects the paintwork by preventing frequent polishing. With a good paint sealant, a polymer that is applied twice a year, owners preserve the paint. A good clue is the formation of drops, when this no longer forms on the paint surface, it is time for a new preservation. Only when traces become visible, I advise a mild polish.
Do you have any tips for interior care?
If you want your car to be clean, you should regularly vacuum it out and wipe the cockpit and plastic surfaces with a damp cloth. It is best to use distilled water because it does not leave stains. Once or twice a year, a special plastic cleaner provides UV protection and cleanliness. That is actually it.
