Aqua Gleam 30ppm

[FaisalJ]

So I got my DI vessel and bits, and thought I'd give it a go yesterday. Bits I bought:

- 24l DI vessel used from eBay
- 25l ion exchange resin
- Hozelock aquastop connectors x2
- Hozelock metal threaded connectors x2
- Cheap water hardness meter



Thought I'd try a no-touch wash of the Golf as it was only slightly dirty (washed last week). Plan was; wheel cleaner, snow foam, pressure wash, walk away. All in direct sunlight too.

Other bits I'd need; gTechniq W6, bilthamber foam, and foam bottle for my karcher.



Tested the water before hooking up the DI vessel. 150ish PPM = hard!!



Loaded the resin into the vessel (which I was dropping everywhere, had to fashion a large funnel out of cardboard) then hooked it all up straight into the pressure washer:



I tested the water coming out and it wasn't 0 ppm which was disappointing but still low at 18ppm.

State of the car before, not horrendous:







Sprayed on the W6 first, then foam a couple of min later





Then washed off! Took a few min for the pressure washer to get going, lots of air in the system, otherwise would've been quicker. The car came up pretty well! Not perfect (had some spots on the sunroof) but still good for an easy 15min wash. I might try on the RS later, and just dry off the glass. Pretty happy with it though!

You just need the DI water for the final rinse - I run it through the hose with the tap 1/3 on and just let the water run over the car (like a watering can would without the rose) there is no point using DI water with soap etc. as the soap will leave marks anyway if not rinsed off.

Try shaking the resin container up and then draw some water through the hose slowly - you should get 0 ppm.

How much resin did you put in ? It should be about to a bit below the shoulder of the tank.

I checked mine - 10 ppm after a couple of years use.
