Can high pressure water from a car wash damage glass?

Yesterday I washed my car at a new place with very high pressure water. Today, there were these tiny ';scratch'; lines across the glass and ';swirl'; lines on the paint on the trunk. I tried wiping it off and it didn't change. The place had 2 car washes and 1 was out of order...maybe something was wrong with the water pressure? Is it even possible to scratch glass with high pressure water alone? It's not like it was a sand blaster... but before I take it to a guy who does individual sponge car washes to see if it's just the soap that got stuck, I thought I would ask here? thanks.Can high pressure water from a car wash damage glass?
I'd say there was grit or grime either on the car or on a cloth or sponge that ground into your paint %26amp; windshield. The high pressure could have pushed it into the paint, or a cloth or sponge could have.





Many windshields have plastic coatings. They prevent the glass from pouring into the car in a crash, but also scratch and haze much easier than glass.Can high pressure water from a car wash damage glass?
It shouldn't, especially with windshield glass that is specially designed to withstand high pressures and a degree of abuse.





But if the glass was already cracked, pitted, or somehow flawed, it has a weak spot that the water pressure could cause to become worse. Sometimes cracks in windshield glass are too fine to see.





Water itself will not scratch glass or car paint finishes, but solid particles within the water could act as a sandblast which could pit or scratch both your windshield and your car's finish.
It is highly unlikely that the water pressure would damage paint or glass. You didn't say, but is this one of those places where you wash the car with a wand and scrub brush? If so, it may be that there was some dirt or sand in the brush from some moron who washed his sand-covered truck with it, but the water pressure would not even come close to the pressure needed to damage the glass or the paint.
It may be possible that particles (like sand and dirt for instance) got into the solution that they used and sprayed onto your car? Thats all i can think of.
