Water spots on ceramic

[BlackRabbit]

My 2022 MY has ceramic coating which has water spots from the sprinkler system and I can't remove them with just basically washing. Any ideas of how to remove them?

Try a clay bar

Use clay bar or synthetic clay towel to remove (microscopic) high points of left over minerals then follow up with water spot remover (mild acidic cleaner) to remove (microscopic) low points. My preferred water spot remover is Optimum MDR as it is a gel like substance that better adheres to paint for longer dwell time. Many other brands have spray on water spot removers that could work as well. If mild cleaner does not completely remove, consider going to pro detailer to use diluted wheel acid cleaner (much stronger acid).

Wow, is that common with ceramic coating?

Ceramic doesn’t make it damage proof simply easier to clean. If the sprinkler water source in his example had a low PH level it could etch into the coating. Like acid rain only not as aggressive.
