Having problems with tds in van tank rising to 12ppm, just filled up scrubbed and rinsed with 000tds several times, water filling tank is on 000, checked tank water, risen again to 10ppm...WTF!!!!    Getting by, by running tank water through Di to hose reel...
What can I clean it with?

[Graham H]

I shouldn't worry too much, 10ppm is perfectly ok for cleaning windows.

I've used Milton sterilising fluid in the past with great success when I've had algae forming in the tank. I put three or four 1ltr bottles in the tank (400ltr), filled it up to the top & left it overnight. Then drained & flushed out with hosepipe the next day.

Might be worth a shot, you can buy it from supermarkets, down the baby isle as it's used for sterilizing bottles etc.

I use the milton tablets when i had tds rising half fill tank or less  and drop a 3-4 in the go for a drive around up and down banks etc to give a good slosh around .

I then totally drained the tank of every drop of water then just filled with pure i have problems with the odd bit of crap getting in my static tank which then gets transfered into truck tank going to install an outlet for transfer pump on side of tank then put in  carbon filter pad . Mike

Milton it is then!!!!!

same as

[H20cleaning]

I jetwash mine out then leave over the weekend, totally drain and fill with pure and works a treat!
My water very rarely rises above 005 and if it does i change the resin.
I dont know how people can get away with 010+ mine
Spots if its that

Yip.

Anything over 005 I've noticed spotting in bright sunlight. I'm pretty much PPB now instead of ppm and I'm noticing a difference.

[H20cleaning]

Tbh 2litres of resin lasts me about 4-6 months, so its not even worth scrimping! Might aswell clean with the best possible water.
And tbh when the water is 000 it feels easier rinsing them?

really i am surprised 

[H20cleaning]

Honestly! Me and my uncle both have sperate WFP business's and we both work to 005 otherwise windows spot!
Even at 005 i can almost see by the way the water is on the window that the resin is due a change! So doesn't rinse quite as easy

Never heard such nonsense! I guarantee you that your spots at 5ppm are NOT from the water, if your eye does see any, it's contamination from elsewhere.

not knocking you h20 , i have worked with water of over 30 by accident by the way , on busy high streets with no complaints , and i know of other guys who have worked with much higher   but i am happier with 000 tds, but i dont worry about it now

I'm with you on that one mate.

I've tested it out, different windows on the same property, different TDS of water in backpacks. I can notice the difference very easily. Esoecially in low sunlight.

The purer your water, the better and quicker results you get.

Certain windows that are WFP friendly and hydrophilic you probably can get away with higher TDS, but on hydrophobic and tricky windows, the purer the better.

[H20cleaning]

I didnt say that you couldnt get away with it, i just know that if i clean windows with above 005 it spots.
Not saying customers will complain lol just i know fine well it spots me and my uncle have both tried it, i have even gone back to re clean the odd one in the summer when the sun dries them really quick and i could see light spots.

But each to their own:)

hey if it works

Why would a tricky window present a difference in finish between TDS levels? This proves the theory wrong as what you're saying means it's the window & not the water.

000 & 005 have zero difference in cleaning ability. Are you saying that your eye can distinguish 5 parts in one million?

[Jonny 87]

Hi winpro.

I'm just sharing my experiences.

A window that is hydrophilic rinses very well and is left almost dry after the rinse, wheras hydrophobic beads up and more water is left on the glass. This is where real pure (000 and less) comes into its own.

5 parts per million seems like very little, but condense that down, to every square inch of the glass, 5 parts of dirt in that square, and the next and the next. Over time it can build up on glass almost leaving a mineral deposit type of effect.

Again, you may well not get complaints, but that doesn't mean the job is perfect.

[H20cleaning]

I didnt mention a tricky window... It has been tried on several.

I'm not saying how it happens, or why but i wouldnt lie when i tell you i have tried and not been happy on a few occasions that the water has dried how it should? I can add it has nearly always been in the summer months on warm days mayby there is an explanation for that?

The beads of pure water on hydrophilic glass will absorb atmospheric particles. In winter, these beads can last all day & so are vulnerable to anything that they can absorb. I agree that the beads are concentrated areas but don't agree that 005ppm water alone would leave any visible mark, if the bead of 005ppm water was in a sterile environment you wouldn't see any marks left behind.
