I have the CR Spotless deionizer as part of the Obsessed Garage pressure washer package with hose reel, piping kit, pressure washer, etc so that I only use the DI for final rinse ($$$ otherwise).

thx. spendy but looks like some quality kit. What does the cost per DI rinse run maint wise (not initial invest wise) if you don't mind sharing.

A common occurrence here on Rennlist where a Toro Leaf Blower works great for $75 on Amazon but some see value in paying $350 for a "Master Blaster" go figure?
Does anyone use Q-Tips to get into those nooks and crannies?
I understand a leaf blower in combination with an ounce of gasoline and a Zippo Lighter will add to the quick-drying effect too.

It's about $50-60 to change the resin, it will treat 300 gallons (depending on how bad the water coming in is). That's the benefit of using the pressure washer for final rinse (at say 1.5 Gallons per minute) you're not using as much resin per wash. I typically get 30-40 washes out of mine, there is a meter on the front that will tell you the filters levels to let you know when its time to replace.

I bought this one a couple of months ago, and I like it a lot (no affiliation):

It’s much cheaper than the Metrovac ($209 vs $350) and it works great.

I dry most of the car with one of those “rubbery towels” first, and then I use the blower to finish it off. It’s amazing how much water is still trapped everywhere even when the car looks dry.

I use this identical set-up with CR Spotless and EGo blower for all the nooks & crannies ... will never go back to hose washing or towel drying ever again. Fortunately, my water is very soft (around 110ppm) so I’ll probably get close to 80 to 100 washes out of it.

I use the DI water unit made by Griot's Garage: https://www.griotsgarage.com/product...r+deionizer.do

I use it with a pressure washer, only for the final rinse. The bypass valves make it easy to switch it in/out when needed. Haven't changed the resin yet, the water still tests good after 1 year of use.

It is better to remain silent and be thought a fool, than to speak and to remove all doubt.

Same blower here. One battery and its ready for touch up with the microfiber towels. Works awesome.

Nice looking unit. Thanks for sharing.

I came very close to buying the DI unit from Griots solely because it had the valve on it. After further research, I elected to do a wall-mounted CR unit (https://crspotless.com/product/diw-2...ounted-system/) and have the input permanently plumbed with valves (on inlet & outlet), and a quick disconnect hose fitting on the output. I have a braided steel hose that I easily swap between the regular wall spigot and the outlet of the CR system - works like a charm!

During washing, I absolutely agree that there is no need / advantage to use non-dionized water ... save it for a final rinse down for about 2 or 3 minutes and you’re good to go! I use it regularly on all of my cars am into my 2nd season of use and am still at 0ppm ... should be able to get thru this season (hopefully into next) without need to change the particulate.

I guess I best not mess with a man and his blow-dryer!

What is the purpose of using deionized water on a car vs water from a garden hose? Thank you.

It ion-exchange resin essentially strips the minerals that commonly leave water spots on the spots . I wouldn't recommend it but you can pretty much wash a black car in direct sunlight without spotting.

During washing using a PH balanced soap can help remove worry about water spots during washing, and then using DI for final rinse prevents it while you complete the rinse and drying process.
