So for some unknown reason, I thought a Black Night Edition Cummins would look great in my parking lot.

Unfortunately, I have hard water at my home and like a clean truck.

So to save myself on carwash bills, I'm looking into getting a Deionized water car wash filtration system.

Do any of you have any experience with these?

I did have a 5-6 yr ceramic coating applied which seems to help, but I would like to wash at home without the truck being white.
