Pressure washers have long been the preferred car cleaning method across the world for car cleaning since their introduction. This has been attributed by their many advantages, which include use of less water and elbow grease that the old methods. They are also preferred as they takes less time than the hand wash. However some car ‘experts’ and worried car owners have also been increasingly asking; are pressure washers safe for cars?
Are Pressure Washers Safe for Cars?
Pressure washers are not without downsides and thus precautions must be taken when using them to clean cars so as to avoid damaging various car parts. Most of them come with a rotary nozzle which is used for high pressure wash. It’s important not to use it as the pressure produced by the nozzle has the potential to damage the car paint. The initial burst shouldn’t be directed towards the car as it can be very strong for the paintwork. Its recommended to point the nozzle to the ground first.
Strong pressure should also not be directed toward areas with chipped paint as that can lead to more chipping more paint from the car. Precautions should be taken when cleaning the tires – more so if they are worn out. Cases of tire busts have been reported when pressure washing worn out tires and thus it’s better not to use pressure washer on tires if they aren’t in good condition.
It’s recommended to clean on a concrete surface rather than a loose gravel surface. Pressure from the machine can cause the gravel to fly and hit the car causing damage, dents, and dings. Such gravel can even strip off the paint, cracking of the windscreen and lights. In addition, the engine bay shouldn’t be sprayed as it can cause water to leak into some parts of the engine causing damage.
That said, when all the instructions about their use and precautions are taken, pressure washers are definitely safe for cars.
