I bought On-The-Go because I liked some things about it better than the competition. I actually hook up a longer hose with a nozzle on the outlet, though it is nice and portable. Great at no water spots!

Where does the water pressure come from?

 

The house, you just hook up your normal hose to it.

competitive advantage of this over the CR Spotless system? Seems to be less popular.

 

It's the same technology and appears to be the same size and price (on Amazon) as the smallest version of the CR Spotless unit. There's nothing really complicated about these things, since they're just canisters filled with resin.

 

I have the twin tank 'CR' and it does work well .. however ... I initially used it for the first rinse and then wash and then final rinse, and you really need to thoroughly rinse at the end or you get streaks.

Anyway, the resin does not last very long, so now I do initial rinse and wash it with regular water (I use a fitting off my water softener) and save the CR water for the final rinse so the resin lasts longer.

Our water is very hard, so the 'softened' water helps, yet the CR leaves a totally spotless finish, without drying.

In Las Vegas everyone has whole house water softeners. I have a connection for it in my garage to use soft water.

 

I'm on a well and also have a very expensive dual tank softener connected to the whole house, irrigation system, and hose bibs, but I still get water spots. Softened water is not necessarily deionized, which supposedly these systems do.

 

I agree, the principle is the same, just mixed resin in a can. OTG is from middle America, CR from the left coast. OTG does not pretend to measure TDS in the flow stream, they provide a separate meter to stick in a glass of water. In any event, while soft water is less of a spot problem, deionized water is better. Even when the Mr. Clean was available, it was recommended to use the filtered path for only the final rinse.

How much do they last, and how much for a new filter/resin for your respective device?

 

No idea how long it lasts because it depends on the incoming water. They say about 30 rinses of a car and I have not had it that long yet. Refills range between $40 and $80 depending on where you get the resin. That should be a couple of years for me.

What I'm wondering is if it would be cost effective to do the following:

Rather than having to wash the car when it gets dirty, just rinse it with deionized water every couple of days.

Most of the dirt on the car seems to be dust that just gets a little too thick.

 

Rinsing will always get some dirt off but never all of it and you don't want to rub the car with dirt on it. Seems to me that frequent rinsing is a waste of effort. Gotta wash then rinse.


Larry

 

Fair enough. The goal would then be to extend the time between every wash by rinsing ( without a towel, just the water).

 

A California duster works great, as long as the car is waxed, and the dust/pollen is loose.

 

+1. And follow up with a detailing polish specific to cQuartz and film.

 

What is this "water" of which you speak?

I do not water my lawn, but I do wash my cars.

You should visit Hetch Hetchy again. I heard it now has some in it.
