8 deadly sins in winter: what not to do in the cold

1. De-icing the window with hot water or a CD case

W If you de-icing the window with hot or lukewarm water, you risk stress cracks due to strong temperature changes. The layer of ice contains dirt, which acts like sandpaper when scratched and leaves scratches on the glass. Therefore, when parking the car, operate the washing system to clean the window. The check card, a hob scraper or a CD case are not very useful as scratches. They only damage the disc. The windshield wipers do not affect the ice layer either and only wear out.

2. Constantly driving at high speeds and short distances

Especially in winter, it takes time for the bearings and lubricating surfaces in the engine to be optimally supplied with oil, and wear is high. Constant short journeys are therefore poison for the drive. Even high speeds can damage the engine in the long run during the cold running phase. On the one hand, the slow penetration of the oil is a problem, and on the other hand, the rapid but uneven heating of the individual components is a problem. This also leads to increased wear.

3. Use the car wash without pre-wash

To ensure that the road salt does not attack the vehicle, the car should be washed occasionally in winter. Anyone who uses the car wash for this should carry out a pre-wash. This is because a dirt-and-salt crust has formed on the paintwork, which can severely clog the paint layer if it is not removed with the steam jet before using the car wash. Important: always select a wash program with underbody wash.

4. Do not grease the seals

If you forget to protect the rubber seals on doors and flaps with silicone or deer tallow, damage is likely. Because then they freeze and tear when doors or flaps are opened. The protective layer on the rubber seals for the frameless side windows is particularly important.

5. Do not replace old batteries before winter

Lights, windshield wipers, blowers, heated rear windows and heated seats - the battery and alternator have to do heavy work in winter. Especially with many short journeys, it can happen that the battery goes to its knees at some point. You should therefore be economical with the electrical consumers in the car. If the battery is getting old (more than four years old) or has been deeply discharged in the past, it can collapse when the frost sets in. If you don't want to wait until the first failure, you can test the battery in the workshopleave.

6. Forget anti-freeze protection in winter

In order to keep a clear view in winter, a cleaner with anti-freeze content belongs in the windshield washer system. If you fail to do this, you not only risk damage, but also a fine. Antifreeze protection shouldn't be neglected either. Usually this reaches down to minus 25 degrees Celsius. This is enough for us, because even if the temperatures drop even lower, it takes time for the water in the coolant circuit to freeze.

7. Sitting behind the wheel with a thick jacket

When the temperatures drop, many drivers get into the car with thick jackets. This is not a good thing because the belt is not snug enough on the body. This can have dire consequences in the event of an accident. In addition, thick jackets restrict freedom of movement. You should take off your jacket before starting your journey.

8. Carrying moisture into the car

Before getting into the car, you should get rid of the snow, otherwise the moisture will get into the vehicle. But it is not entirely avoidable. If you ignore the moisture, you run the risk of windows steamed up from the inside, mildew, mold and rust. Therefore ventilate well regularly and turn up the heating. The air conditioning also dehumidifies - but only as long as the outside temperature does not drop below six degrees, because many systems switch off there. Take out wet floor mats and let them dry. In general, it makes sense to switch to rubber mats in winter.

Other DONT's:

  • Newspapers and cardboard are not suitable for covering the front and rear windows in the evening . They get damp and stick to the windshield.
  • Allowing the engine to warm up on cold winter days is not only disruptive, polluting and harmful to the engine, it is even prohibited according to Section 30 Paragraph 1 of the Road Traffic Regulations.
  • De-icer spray: Only makes sense in combination with an ice scraper and with a thin layer of ice. Because the windows get dirty and have to be cleaned afterwards.
  • Never put a heater in the car, the heat does not work evenly in the vehicle. Plastic parts of the interior cladding can be deformed by the effects of heat - in the worst case, a fire can even occur.

That helps: DO's for cold days

  • Always fold up the windscreen wipers in the evening so that they do not freeze to the windscreen overnight. Ice residues in the wiper blades can be removed with the furrow in the triangular scraper.
  • The right ice scraper saves time and energy. Use an ergonomically designed device (such as the MID-IS) and place it on the pane at an optimal angle of 30 degrees.
  • The right scratching technique is also crucial: the ice only ever in Scrape off in one direction so that the dirt is not rubbed back and forth on the window and causes scratches.
  • In addition, the car windowsclean regularly with plenty of water. Because: Whether or not car windows scratch when removing ice depends primarily on how dirty they are.
  • Remove snow from the entire car. In addition to the windows, this also includes the vehicle roof, the hubcaps, the side mirrors, the headlights and the license plate.
