I've tried the Mr Clean car washing system and it worked fine. EXCEPT that the water around here is so hard that the rinse cartridge lasts only for 1 1/2 washes. I saw an RV water softener on eBay ( http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=4545111098&category=50070 ) and if you read the hype, softened water will do everything the Mr Clean system does.
So, do any of you rinse your car with household softened water? Does it dry without water spots? Seems like over time the eBay softener would be a bunch cheaper to run. Along those lines, is the Mr Clean rinse cartridge a water softener? Do you think its possible to recharge the cartridge? -- Rick Schaefer 72 TPI El Camino
