Why don't you wash your own car?

Any interest for those that like washing cars to have a Meetup,at my,house in OC to wash cars together. Warning chiparhina and wine may be involved along with fried food

 

If anyone tells you you can filter to 0 ppm without reverse osmosis, run. Even reverse osmosis will leave some TDS. People also don't understand the difference between TDS and Water Hardness. They are not the same. Softened water still can have high TDS, but since the hardness is reduced it's doesn't leave spots. It's hardness you should be concerned with when washing your car

The CR system is a water softener. One that doesn't regenerate. Why someone would pay this much for it is beyond me. You have to replace the resin often because it doesn't regenerate like your home system.

Better off pulling softened water from you home. It regenerates and will cost pennies per use.

People love to scam people with water filtration. I used to work for Pentair Filtration Everpure) BTW and had to educaate so many people that were scammed by ridiculous claims by filtration salesmen. Magnets, oranges, etc. All snake oil.

To the person wasing their car in rainwater....don't. Rainwater is acidic.

If you get high mineral water off your car (you don't let the sun bake the droplets and leave spots) you will be fine. If you get a lot of rain, sounds like it's not that hot outside. I wash my car in 340 ppm TDS water and there are no spots or etching on it

This is not true. PPM would indicate TDS. Grains indicstes hardness. Worry about hardness

If have hard water coming into a softner, it actually leaves with more TDS than it started with. Yet it doesn't leave spots. How? Because the hardness is reduced. Specifically Calcium hardness. It does this by exchanging sodium ions with calcium ions through the resin. Then it recharges with the salt solution.

Don't do this. Rainwater is acidic. It also catches pollutants as it falls through clouds and the atmosphere.

Ever hear of the term acid rain?

You CR system and your home system are both water softeners. I am basing this on you mentioning salt. TDS is every mineral and solid in your water. Some of those are not bad Hardness is what is bad, but only if you let it sit and dry. It's measured in Grains. If you had hard water but wiped down your shower door everyday, you would not have spots. The spots occur because you leave it. Or you get a softer to treat so you don't have to wipe. When. You wash you car, you wipe it right? I wash my car with hard water (434 ppm TDS and about 22 Grains Hardness) and don't have issue. Because I wipe it off.

The CR system is not bad for your car. Let me give you an analogy. You have an empty refrigerator. But you decide to keep soft drinks in a cooler and use ice you buy from the store when it melts. This is what you are essentially doing.

Water threatment is super simple. Basically there is mechanical filtrstion. Like a screen. Smaller the holes. More it filters. For practical home application, mechanical filtrstion can not filter out minerals. Then there is Reverse Osmosis. This filters out minerals. But is very slow and not practical with consumer units. Then there is softening. Softening is not filtrstion. It exchanging ions so that the calcium ions become sodium ions. The calcium creates the scale. Within softening you can get a salt system where you add salt and it regenerates. Or you can get a sealed cartridge system that salesmen love to sell you because they make a ton of money on you for the change outs and frequency of those.

I used to give away cartridge systems if customer would sign a contract to change catrtidges with us. Money is made in cartridge changeouts.

Water treatment at home or for washing cars is super simple. Anyone that tries to make it more complex is trying to make extra money off you. It's ok as long as you are informed.

 

this will work. Distilled water doesn't have minerals in it either.

 

DI is similar to softening. You can use salt, potassium , chemicals etc to charge a resin bed. . Some manufactures even use oranges. Ha ha. The resin is charged with something to exchange ions . It's not exactly softening but for the sake of car washing, it's similar.

It's not the same as distilled water. It's easy to prove this. Put a TDS meter in distilled water. It will read 0. Put a meter in the water coming out of the CR system It won't be 0.


The key point is, unless you are washing your car in direct sun and letting water dry into your car and not wiping it off, all of this filtration and water treatment is unecessary . This is not a slam on the CR system. I have a very expensive and complex water treatment system in my home. I use unfiltered water out of a hose to wash my car and it looks better than when it was brand new. I simply don't wash it in direct sun or let water dry on it.

The other key point is if you have a softener in your home, it was be so much cheaper to use that water to wash your car than the cr system and get the same result.
