I have finally taken some time to do a review of the virtues of owning a CR Spotless water system. I did another quick article on this system that might answer some of your questions.
I have owned one since last year, and really like all the benefits. These include: increased cleaning ability of soaps, no phantom water runs on paint (you know the kind that come out of unknown crevices), ability to wash in full sun, and true ability to do a home touch-less wash and dry. I mix most of my chemicals with DI water to increase effectiveness. ONR and DI work great.
What I’m trying to show in these photos is the difference in foaming ability with and without the CR Spotless.
With the CR spotless in use, nice thick long lasting foam, excellent dwell time
Without the DI System, thin short lived foam
These water drops will not leave ANY spotting behind, it would be cool to show a time elapsed video of the drops drying! You can also see this paint has not a spot on it after drying in full sun.
I’m extremely happy with my CR Spotless set up, as we have pretty hard water here. If you have a DI system, please post your results.If you don’t have one, you should strongly consider one so you too can achieve a true spotless wash.
