Car paint needs protection – against scratches, bird droppings and in front of the car wash.
BMW ColorSystem expert Martin Jaworski shares the best tips for washing and caring for your car paintwork. How to give your car a shine.
Paint pests: bird droppings & Co
Not only good things come from above. Bird droppings and other animal excrement are corrosive. “And the longer the caustic substances act on the car paint, the greater the damage can be,” explains Martin Jaworski, Product Manager BMW ColorSystem.
Another damaging factor for car paintwork: the sticky film that covers cars parked under linden trees in spring. This phenomenon is called honeydew. Sounds cute, but makes drivers angry. Because honeydew is the droppings of aphids. They suck juice from linden leaves and excrete sticky sugar. This film can burn itself into the paintwork in the blazing sun.
“Such damage is irreversible and must be professionally repaired,” warns paint expert Martin Jaworski. Hence his tip: wash off bird or lice droppings as soon as possible!
The same goes for insects. A special insect repellent removes the animal remains from the car paint, which can then be easily removed during the subsequent washing.
Lacquer problems: the most common mistake
Those who love their car wash it at weekly intervals. Because, according to Martin Jaworski, neglecting continuous maintenance is the most common mistake car owners make. “If the car paint is properly cared for, it is generally more resistant to external influences.” Expensive repairs with paint spray and touch-up pencil can thus be significantly reduced.
“How often you should wash your car depends on the type and use of the car,” says Martin Jaworski. But one thing is certain for the BMW expert: “Frequent washing does not damage the car paint if you pay attention to a few things.”
Paint lovers: the optimal washing system
There are car washes with brushes and those with rags. One is no better than the other, says Martin Jaworski. But: If the brushes or rags are soiled by sand, for example, they act like sandpaper and stress the paint surface. Therefore, very important: the car wash itself must be clean and well-maintained. Who likes going to a dirty bathroom? And take a closer look at the brushes. If the nylon threads are brittle or torn, dirt can build up there.
And after the wash cycle, another wax cycle? Absolutely! “The wax seals the top layer of the car paintwork and thus protects against external influences,” explains the BMW expert.
And at what intervals should a wax treatment take place?
The expert’s rule of thumb: As long as rainwater drips off the car paint properly, no new waxing is necessary. However, the weather also plays a major role. If you park your car in a garage, the layer of wax protects longer than under a carport or outdoors. If you want to be on the safe track, the expert recommends the double interval – let it grow once in spring and then right before winter.
Lacquer and rags: the right hand wash
Do you prefer to do the car wash yourself? Very exemplary! “Hand washing is considered the gentlest wash by car enthusiasts,” says Martin Jaworski. It is important to use mild cleaners with a low pH value – as well as soft and clean sponges, brushes and rags.
“When washing with a high-pressure cleaner, the same applies as on the motorway: keep your distance!” Says Martin Jaworski. Because too high a water pressure affects the car paint. “The correct distance between the spray head and the car paint depends on the device and model.” Rule of thumb: If the water jet hurts the hand, it also hurts the car.
Shining again: the car polish
Is your car’s paintwork not as shiny as it was on the first day? Or do you see slight scratches? Then it’s time to polish. A car polish contains microfine abrasives. They gently clean the paint surface without damaging it. At the same time, a polish preserves the refreshed paintwork and protects it from the weather.
Touch up paintwork: with a pen or spray against scratches
Have you polished your car but you can still see the scratch? Then the next step is mending – or better: having it mended. “The best way to carry out the paint repair always depends on the specific case,” says Martin Jaworski. “Therefore, trained specialists should carry out the repair.”
You don’t have to buy a new car because of a scratch, because you can get help to help yourself at the BMW dealership. In the form of advice, touch-up pencils and spray paint All you need is the correct color code for your vehicle, which you can find on all BMW models, for example on the nameplate, which is attached to the B-pillar or in the engine compartment, depending on the model. You can also ask for the color code from the BMW dealership. The right BMW colors for spray paint and touch-up pencils can usually be easily identified using the vehicle identification number.
