Washing with de-ionized water


Vehicle Information: Model: Carrera; Year: 2007; Body Type: Coupe; Total Mileage: new;

I live in a hard water area (TDS - 602 ppm avg) and am looking into purchasing a de-ionizing water filtration unit for washing my soon-to-arrive 2007 Carrera. Based on sales claims ( washing/rinsing with de-ionized water appears to be a great solution to water spotting and freedom from scratching from drying cloths, chamois, etc. Please give me your views on the subject. Thanks!
