I tried to search for the anser, but could not find the answer....Will the water you buy for $.025/gallon from the outside vending machines found in shopping center give you water which is considered "spotless" water for rinsing? Thanks in advance
 
I'm not really familiar with the vending machines you are referring to, but "filtered" water is a lot different from "deionized" or "distilled" water. Minerals are dissolved into water and cannot be filtered out. They can only be removed by distillation, ion exchange, and to some degree reverse osmosis.

I am referring to those machines where people bring their 5 gallon water jugs to fill up for drinking water. The filter process described on the machine indicated that one of the steps involves Reverse Osmosis.
 
Those machines only use Reverse Osmosis. This will remove about 75% of the minerals.



Normal tap water usually has any where from 300 to 400 ppm (parts per million) of TDS (total disolved solids). After the tap water is ran through the RO unit it will bring the water down to about 30ppm of TDS still leaving the minerals. Now, after the water is ran through a deionizer, it the bring the water down to ZERO TDS. What is left is PURE h20.
 
I still get spots with RO water, but it is a heck of alot better than tap. I also think that the RO water works better with ONR than tap. At 25cents a gallon, the price is right.
 
I guess this water will do for this weekend's wash. As I work at a pharmaceutical company, I have access to pharmaceutical water (which goes thru a pretty elaborate process of double RO and membrane deionization filtration) which I take home every weekend to wash my 335. Unfortunately this week, the filtration system was down.
