where do you go to buy the stuff??

Here's a chart to show the freezing point of isopropanol in water. I reckon you would need ten percent for a normal english winter. So that's six and a half litres for a 650l tank?

sean i paid a tenner from maplins for a litre total rip off you can buy it from ebay much cheaper. or a medical suppliers but to be honest i only used it a couple off times when it was really cold. i still have that 1l bottle in van cause i never needed to use it tha often
-
at a tenner a litre you dont wanna be using ten percent!! Thats like half a days work for 1000 litre tank!!

i pay £30 per 25 ltrs so around 60p per half ltr .

hi , where do you get your supply from and is it the 99.7% stuff? i paid that for 15ltrs + postage. And thanks for all you replies 8) Syd

The correct ratio is 285ml Isopropanol on 500l water.

give these guys a ring specialist aerosols 01226 387101 they minght try to charge you £40 for 25 ltrs but just tell them that dave shaw says its £30 , i dont know what delivery charge would be , if you do phone and they try to charge more than £30 let me no and i will phone them , its the correct stuff 99.% .

Got it from NWH, ask him. :)
But it certainly seems to work well for me.
-

So what's that? 0.057%? anyone else have a go?
Look at the chart then tell me how effective that is as anti-freeze?
-
Or a wetting agent or a solvent cleaner? It's so miniscule it would be almost undetectable, you could drink your ro water and not notice it. Wake up guys you are wasting your money. ::)

Thanks Daveshaw for the suppliers tel. no. I will give them a buzz when this 15 ltrs is used. I tried it for the first time today. Put 1/2 ltr per 250lts water in van tanks, probably too much, but no adverse affects.The only difference i can see from using just pure water is that a). it froths/suds on the glass a little, giving the impression that you have soap in the water- but it evapourates quickly. and b). It gets those snail trails of with a lot less effort. Is it worth the expense even at £30+ per 25 lts?(that should treat 10,000 lts at the ratio i used today) not sure yet, but after the first day i quite like using it for some reason. So we willsee. Thanks again for all your comments. What reasons do you all use it for all year round? 8) Syd

this mite sound daft how do u insert this into an ionics tank???????

Funny that you still haven't actually tried it yourself, so you shouldn't speak about it really.
