Personally, I think that your windshield must have spent more time exposed to UV rays, and more time subjected to mechanical stress due to expansion/vibration, and mechanical stress due to air mass pressure due to velocity, than more time subjected to the action of a liquid. windshield wiper, which was designed for that, to clean various surfaces. That it comes in a plastic container, and that it is placed in a different plastic container in the car's windshield wiper, and that the liquid usually spends much more time in contact with those plastics, and I don't remember seeing cracks... But of course, if that An expert in corrosive liquids said it, I do not have the ability to contradict him...only the experience of using it for the last 25 years...in the interior cleaning of my vehicles, in the cleaning of my motorcycles, and in the cleaning of my home…..
This is the headlight of my truck. 3 years...150,000 miles...I clean it 4/7 times a week with glass cleaner...it is not cracked...my driver's seat (synthetic leather), the same miles as the headlight...cleaned every day...
And the cleaner on the back door…
