I loved the Mr Clean system but i have heard they stopped making them and i can't find them any longer at Walleys, Pep Boys etc...

I went a bought a 3 gallon sprayer at Home Depot and go to my local supermarket to get Distilled water. I use the S 100 then rinse very well, then spray with distilled water ( no minerals in it so no spots), leaf blower to dry.
I started doing this with car with regards to rinsing with DI water, same idea as the Mr Clean but actually even better because the Mr Clean is not true DI water it just exchanges ions, anyway that is a whole other blog
