Hard water stain

[Tjdave]

Looking for suggestions. Just traded up to a 2018 Tiffin 32sa. Barely used and the paint is beautiful, except for a hard water mark running down the side under the HWH. Any suggestions on how to remove it? You can actually feel it over the paint. I tried a little wax to no avail. I don't want to wreck the paint with the wrong product. Thank you for any help.

Vinegar will dissolve calcium. I'm guessing that is what is staining the finish. It sounds like it's been building up for a while if you can feel it. If that's the case you are going to have to work it a bit. It may take some time to get rid of it but you should be able to tell if it is working fairly quickly.

Good luck

Along with above post, I've read that Chemical Guys heavy duty water spot remover works well. Haven't had to try this yet. I do know that dishwasher soap works on chrome mirrors. Don't know if this will harm clear coat/paint.
