I am in process of reading the manual, and came upon this:"Some car wash installations usewater at high pressure. This coulddamage certain parts of your vehicle."
The place I usually go uses high pressure wands. What parts would be damaged? I read earlier in the petrol filler flap should be avoided, but is there anything else?

Hi fanbelge, from a personal point of view i would never let any of my vehicles any where near a car wash!!

Rear view camera

Along with the rear camera, the manual also mentions the fuel filler cap. I guess they are thinking of water getting into the fuel system. Any high pressure system trained on them for a prolonged time would not be advisable, though they also say do not use the high pressure spry too close. I think "common sense" is the phrase to apply in this case. Still beats an auto car wash!

Thanks for the feedback!No rear view camera on my car. Will be careful around the fuel filler door.

Not surprising they say that in the manual. If you have a pressure washer, stick your hand in the jet (you'll only do it once!! ) to feel how powerful these things are. Likely to force water past any seal if you use it too close to the car.

Then again, they tell you to take care using a pressure washer but the dealers still let their 16 year old trainee loose with his grit filled sponge, bucket of dirty water and 100 year old chamois on your pride and joy when it's in for a service. Then they proudly tell you that they've washed the car for you!!

Always tell them not to wash my car and leave a large notice taped to the dashboard "DO NOT WASH THIS CAR"

Took me ages to remove all the scratches and swirls form my paintwork the first, and last, time they washed the car for me.

Same goes with all these hand car washes that have sprung up recently. Most of them use aqua blades to wipe the water off the bodywork after it's been washed with "The Gritty Sponge of Doom". One piece or grit caught in those blades and it gets dragged all the way down the panel!! DIY is best everytime for me

The easy fuel system nozzle doesn't have a cap on it - just a spring-loaded door. It'd be fairly easy to get water in the fuel system using a high pressure hose.

The bodywork fuel flap doesn't seem to seal against water too - I've found water behind the flap after driving in heavy rain.

After treatment with a pressure washer, white water spots are common, which remain due to the fact that microorganisms remain on the paint and form spots that spoil the relief and appearance. Even in the article on removing water stains from a car How to remove water spots from car | Water spots removal, one can conclude that it is better to use a steam cleaner when cleaning the car and high-quality detergents on an anhydrous basis. Be sure to do the same polishing with a clay bar.
