Omg who cares what it does run everything through your ro or just di as some do check tds people that like 000 then once it rises change resin those who are more confident then run it on what Eva highest tds they will run it on we are window cleaner s not bloody scientists.

Wow you are great in debates - who cares! I think you'll find a lot of people on here are curious about what ppm you can clean windows at and listening to others advice and experience

[SeanK]

A tds of 004 = 4mg of dissolved solids per kilo/litre of water.

4 ppm would be 4mg dissolved in a thousand litres of water, not one litre.  So just under a teaspoon of soluble impurities in an IBC brimful of water.

No your wrong Vin, TDS is measured in mg per litre not ml per litre, in other words its measured in weight per volume,
strange but true.

Also 4 mg is not just under a teaspoon in fact just under a teaspoon would be about 5000mg

I think perhaps, you're confusing mg with g.

Ah, that'll be because I read it as grams, not milligrams!  Der.

I don't mean the 000 to 020 i mean all this crap about everything else its all mumbo jumbo to bigest part of window cleaner s ,if they wanted  a science lesson they would probably go back to school,

We put water in a filter and through some resin stuff and it comes out ready for us to splash on peoples windows and charge them alot of money for it. I go home and spend that money on bills and other things.

Lol, im sure thats not the real mentality of most window cleaners.  Ild like to think we all know or would like to know more about their jobs than that.
