Hands off oven spray when cleaning the windows
With special cleaners, rims are usually bare again. The home remedy oven spray, however, should not be used. It works worse and can attack components
There are many tips for the well-being of a car. But which of these pieces of advice is correct? And which ones are harmful? Some home recipes are dangerous for technology and health.
E.There are many tips on car care, miracle cures, secret tricks and things to avoid at all costs. But as it is with myths: some are true, others are wrong, still others were once right, but have been overtaken by time. Is Hand Wash Really Better? Are alcohol or oven spray helpful? And how tight should you actually tighten wheel bolts? We get to the bottom of some old car myths.
For example, there is the car wash. Many advise not to have the car washed in the facility if possible, but to do it by hand – it is gentler and more thorough. The answer to this is a clear “It depends”. On the one hand, you catch a few angles and beads by hand, where the rollers of the systems usually fail. In addition, you can vinify by hand until a spot is really clean.
On the other hand, car washes wash road salt and the like better off the sub-floor. And by hand you run the risk of rubbing the paintwork with dirt in the sponge for too long. The result is scratches, so rinse often. In addition, when hand washing you should avoid the blazing sun and place the car in the shade. Because care products dry out faster in the sun and leave stains that are difficult to remove.
Dirt doesn’t protect the paint
But you shouldn’t do without washing completely. Because the myth is also wrong that a layer of dirt on the vehicle protects the paintwork. On the contrary: apart from the fact that a dirty car is not particularly attractive, dirt binds moisture and salts directly on the surface and thus provides a good breeding ground for rust. Dirt also increases the likelihood of scratches when particles of dirt rub over the paintwork.
Another nonsense is the tip to fill the windscreen washer system with alcohol instead of windscreen cleaner. Because alcohol is cheap and actually prevents the water from freezing. But still he has no place in the system. Because instead of removing dirt, it just smears it, alcohol forms strong streaks and also smells penetratingly.
Household washing-up liquid should also not be used. They do remove insects from the windshield, but they can cause problems in newer cars: They usually have very fine fan nozzles that can quickly clog if the mix ratio is incorrect. Therefore, only the intended means should be in the tank of the car wash.
Do not overtighten wheel nuts
The situation is similar with the well-known oven spray. This is recommended every now and then to clean the rims, especially to loosen stubborn brake dust from them. But: "These products are not intended for use on the rims and can attack the wheel nuts, for example," says vehicle expert Hubert Paulus from ADAC. The same also applies to acidic products. Special rim cleaners are now available cheaply and are better suited to the task.
Some pieces of advice are downright dangerous. For example the tip that wheel bolts have to be tightened with great force to hold securely. If you do this after changing a tire, you can damage the screws in the process – and if it gets stuck it comes off, as an old screwdriver rule also says. Therefore, you should strictly adhere to the tightening torque from the operating instructions for the car, then the screws will stay tight.
And, speaking of wheels: If you lower the air pressure, you won’t improve traction. At least not if he doesn’t intend to drive up sand dunes in the desert. If, for example, the pressure in the tires is reduced in snow, the driving force will be reduced and fuel consumption will increase – not to mention the risk of a puncture.
The manufacturer usually specifies the optimal tire pressure for each car. The information is usually on a sticker that can be found in the fuel filler cap or in the driver’s door. In any case, the values are given in the operating instructions.
