Spot free rinse

[nht mike]

Has anyone ever used an automatic dishwasher type rinse on their truck? I hand wash my cars, but use a pressure washer to prewet and rinse. The washer has a low pressure applicator for soap and I was wondering if I could use it for something like the "jet dry" my wife uses it the dishwasher. I have used Adam's detail spray before drying and it makes quite a difference.

Rain-X has a spot free auto shampoo. I use it in my pressure washer and like it.

The car wash I go to uses deionized water for their spot free rinse, it does an AWESOME job.

I have deionizer tanks for when I rinse my vehicles off after I wash them. Works like a champ.
