I know there are companys out there that have water filtration/soft water systems for your home. Are there any for mobile detailers? I know I could use the same set up but it could get VERY costly. I can't think of any companys of the top of my head but there are some that last 100 gallons and then you have to replace the filters for $120 or something. Well I use 100 gallons almost everyday. I need something that can soften my water without making me broke. I don't think there is a solution for this but just thought I would ask.
