Anyone got one? How do you find it?
(read all the DW threads I could find)
Correct washing technique should really negate one of these IMHO
BUT with a black car, I can see where your coming from
Polished Bliss also do one too -
BH, I'm amazed there's some detailing kit you don't have?! I would have preferred Misano Red but apparently the laquer peels eventually. Sepang Blue would have been next but when I ordered it was an Audi exclusive. Guttingly it's now a standard metallic colour.
So back to the filters. The reasons are two fold. To avoid particles in the water and to avoid having to dry the car (time saver). I never have enough time so that angle is very appealing.
The Aquagleam filters don't last long. Raceglaze do one that works out better value:
However once you start digging you find DI resin vessels are all the rage amongst window cleaners hence there are other places to get it. e.g.
So here in West Berkshire the water from the tap reads 223ppm. Brita filtered water is 164ppm. Our house has a water softener but the reading from the softened water is the same, 223ppm. That's because they work via Ion exchange so you swap calcium ions (stuff that makes hard water) for sodium. Rain water in our water butts measures 38ppm.
So if I want 0ppm water it'll have to be this.
You can see spots forming on the paint even if you are really quick about getting round to drying but they buff off OK.
Have often thought about one, but no, I keep resisting lol
Where we live, our water is classed as 'moderately soft', so really don't need one IMO
As above, our water is classed as 'moderately soft' at 34mg/l as calcium (don't know how that converts to ppm TBH)
We've had the wife's metallic black/red MINI JCW, from new,since September 2013 and haven't had a problem with water spotting
I got my water results from here -
Will certainly have a look at your links tho' buddy - cheers
Ah our water is hard/very hard. It kills kettles, showers, washing machines, etc. The official figure is 241ppm calcium from Thames Water's website (not sure how to do the conversion either). I thought the water softener would fix it but once I understood how it worked I could see why you still get water spots. So as a detailer it's a constant battle.
Being a nerd I bought a TDS meter a few quid from EBay and measured it myself. If I get a DI vessel I'll let you know how I get on.
Hey BH, mg/l is the same as ppm so 34mg/l is 34ppm and yes that's pretty soft water
Scotty 276ppm calcium will trash an in line filter in no time and you will not get zero ppm hardness unless you oversized it which could end up being a sizeable vessel?
One thing you could try is buy a 25ltr drum of DI water and use it as a final rinse through a watering can, you would probably use 2-3 litres max? This should be enough to remove water spotting
Hope this helps?
Should have said minimise or eliminate water spotting, not remove !
That will explain why my skin is so soft then ...
Hey Schuey, thanks for your comments. If you look at the link I posted above they actually have a calculator to show you show many litres you'll get based on the ppm.
The Raceglaze one is 7 litres but the commerical ones tend to be 11.7 litres. I believe 0ppm should be possible, as you say it's how long it lasts. Based on the calculator I'd get about ~500 litres. That should be fine.
This was very helpful... http://www.detailingworld.co.uk/forum/showthread.php?t=104955
Thanks again for the comments.
LOL, BH. It's probably the amount of car washing you do, hands that do dishes/wash cars?? Your tap water is softer than my stored rain water! I don't filter the water butt water. It's one option I've considered. Could do a final rinse with that.
Had a read through the DW thread, I do not see any need to pre-rinse with demin as you would presumably wash with normal tap water and shampoo etc... This would contribute to TDS and leave marks if not rinsed correctly. ( As we know)
So do your normal wash routine, final rinse off with a few litres demin and based on your water hardness you should get almost 3T demin water!! Just be aware that chlorine in the mains water will also shorten the resin life but hey not much you can do unless it has a carbon filter in built, but then where do you stop?!
Right now it's raining so hard, so frequent, I have abandoned the wash routine, with a good LSP and a quick blast of the wheels the weather is keeping the car clean (ish)
Final thing dude, just watch the water from the butt as it can contain suspended solids ( undissolved particles) which could cause very fine scratches when washing/drying undoing all your hard work !
Roll on some good car cleaning weather
I have one and use one. If you are obsessive then i suppose it is worth the money. Had mine about 2 years. I could do with replacing the resin.
Thanks. Which one do you have? Do you wash the car without drying it?
I bought the 11 Litre DI Vessel Complete (8"x17") Filled With Resin from Daqua - i think I paid just over £100 inc delivery. that plus a pet vaccum blower - i never dry the car.
Who thought washing a car could be so scientific
Thanks everyone for the comments. If I could work out how to filter the water butt water that might be the cheapest option. At the moment there is sediment in there which is why it reads 38ppm. So Schuey you are right it would need some work before it'd be safe to use.
Nimbus thanks for the feedback on the Daqua one, it's one of the ones I have been looking at.
BH you are right, who thought there was so much science! If I could rinse without drying then it's one less contact with the car so again reduces potential swirlage!
I have one of these from daqua - 11L version as mentioned above. I mainly got it as where I live in berkshire the water is ridiculously hard. I measured it at over 400ppm - which is just the right side of being undrinkable! When I washed/rinsed the car i would always get water marks no matter how carefully I dried (and I was pre-rinsing/foaming, TBM wash, pat dry with drying towel etc.
I looked at the aquagleam ones and they just weren't economic. I've had this filter just under 8-9 months and it started from 0ppm water, and has just risen to ~20ppm, so might need to swap the resin. When I do a open end hose rinse with this, almost all of the water slides off leaving just a few drips remaining. Practically no water marks either. Personally I consider it worth the money. PS you don't need to do the whole wash with the filter, just the final rinses..
@scotty76 - Thought you may find this interesting
So my area (glos) listed as hard to very hard...NO ****! Going to get myself aquagleam 0ppm filter and see how I get on and report back. If it doesn’t last that long may need to look at daisy chaining 30ppm then 0ppm together, but reckon should last a fair time as it is really only for final quick rinse....he says!
I went through 2 aquagleam filters & daisy chained them before I realised I was much better off biting the built and getting a DI vessel and refil bag of resin. You’d be surprised how much water you use even for just a final rinse. also if you have very hard water you’ll be lucky to see more than 10 uses with the aquagleam.
Ouch! Oh well, guess I will find out how hard my water is, and how many uses I get out of the filter. 10 uses isn’t a lot, but then at £50 odd quid still cheaper than paying some numpty to wash my car with their bucket of grit . As I said, I will report back, but to be honest if this does the job and only lasts 10 final rinses I will then know the value of 0ppm, so can then “bite the bullet” as it were and go for refillable solution.
Thanks very much for the input
Just checked my area, and listed as hard (no S**t) - 324 ppm!. As mentioned aquagleam on it's way, but if I go through that too quickly, may look at a refillable as @Keef suggested. Something like: http://www.raceglaze.co.uk/car-care...-car-washing-filter/customer-reviews-tab#tabs
Which is £100, and £45 for refills, but with 7 litres, should last 486 litres (based on their calculator I hasten to add)
Did my 1st final rinse with aquagleam filter, and to confirm, I had 221ppm from the tap, and then 0ppm once run through filter. so not the 300+ as per TW website.
I have to say, what a breeze to dry post the final rinse, but at times I may just since off dust and leave to dry. It was late so no point leaving to dry in sun, as that was gone. so 1 rinse and counting. It may sound odd, but it felt like the (black) car was much easier to dry with my woolly mammoth, a alot just ran off.
Keep us posted @q5man ! My reason for getting it would be to rinse and walk away. I want to save time. Are you going to try that?
Says he who mixes all sorts of concoctions of detailer spray. Lol

@q5man - Lol
@scotty76 - Absolutely plan on doing that, and will keep you all posted
