Mike,

I use deionized water for entire wash as I don't use a ton of water. Most people would probably only use for rinsing. Works best with power washer as you use less water. One day while in Miami I asked Newell how they kept all of their coaches so clean. I learned They use deionized water to rinse the coaches after they are washed. It's the single best investment for washing my coach. There's not a spot on it after rinsing. Not a spot.

CR has a system that is portable and that's the reason I have it. But their resin (refill) is high priced, so I buy it locally and there are other suppliers online that are cheaper. Griots is fine but the tank is small as it's geared towards cars not buses so you will need to refill the resin more often.

The washes per refill (how long resin lasts) is based on how much solids are in the city water and the gallons used per wash. Or if you leave water sitting in the resin (don't use it) for a long time it decreases life of resin. I don't know the exact number of wash rinses I get but it lasts me a while. I keep my coach very clean so I do wash it often. However, the fact it's so easy to do increases how frequently I wash it.
