I haven't tested the TDS of 97% pure IPA, but I decided not to take the chance and go for 99.9%, which is 000 TDS. Even for the 97%, it might be parts per billion, and still be 0 TDS. I'm not 100% certain.

oh yes 22 years , but at last i'm free . started this lark about xmas time not as well paid as printing but far better way of life, hopfully it will get even better during the summer months

It gets better, takes a while and before long the money starts to improve, once you start getting work from word of mouth you know your doing ok. Over a year for me, still getting a few gaps and poor weeks but something usually pops up from nowhere. Do i miss the print trade? Not one little bit!  ;)

Does anybody on here use both hot water and Isopropanol? I would think there is some sort of risk with a heater and a flammable liquid? Luke

Never one to be put off by risk of explosion,... I'll be testing this nest week!  ;D ;D ;D

A mate of mine ordered the IPA for me (He got in a big batch for making bio diesel) before I ordered the hot system,... and its been sitting in hos house for a month. I'll pick it up Monday and try it out.

Would it really cost £3 a day to use it???? My hot system costs less than £1 per day to run!

It would be for me about 1/2 ltr a week so about 75p per day

That's much better! I was thinking some of the dilutions mentioned were a bit high! I'm going to go 1:1000 to begin with,.. 400 ml in my 400 litre tank, and see what happens.

Personally, all it does is to help the water wet the window better or sheet and didnt make any difference to how it dried paticulary on hphobic, - but I could be very wrong.

As a wetting agent in printing it's mixed with water at ten to twelve percent in cooled water not much above freezing point to avoid evaporation. The quantities used on this forum are miniscule and uncontrolled. I would be very suprised if there was much benefit. I could be wrong.

Any of us could be 'very wrong', but you have to try these things.
But I could be wrong.

How about a dash of white vinegar in your water?  ;D

Does anyone know if Methanol can be used instead of IPO?

Cheers

ive tryed this and it works but did notice a rise in the tds reading ...    one thing ive noticed while using ipa is that the windows dry quicker than just using pure water so thats another benifit of using ipa .
where theres muck theres money

Surely the alcohol evaporates off before the water and if your using a whiskey glassful per tank then the amount on the glass must be neglegable? Chuck in a litre and your still 650 : 1 What's that less than 1%? you could drink the stuff at that dilution and not notice.

Also you have no way of knowing your dilution rate just by chucking a bit in the tank every few tanfulls gives you no idea of how strong your solution is. If it's floating on the top and not evaporating anywhere then your solution will get stronger over the months. The only way to accurately measure what your doing would be to measure the specific gravity with a hydrometer at the point where the water contacts the glass before evaporation - you'll probably find the reading so small that your using pure water anyway.

Isopropanol by the way is excellent stuff!
 Appearance: clear. Flash Point: 12 deg C.
Warning! Flammable liquid. May cause skin irritation. Hygroscopic. May cause central nervous system depression. May cause kidney damage. May form explosive peroxides. May cause reproductive effects based upon animal studies. May cause severe eye irritation and possible injury. Causes digestive and respiratory tract irritation. Target Organs: Kidneys, central nervous system.

Potential Health Effects


Eye:
Produces irritation, characterized by a burning sensation, redness, tearing, inflammation, and possible corneal injury.
Skin:
May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. Prolonged and/or repeated contact may cause defatting of the skin and dermatitis. May cause irritation with pain and stinging, especially if the skin is abraded.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause kidney damage. May cause central nervous system depression, characterized by excitement, followed by headache, dizziness, drowsiness, and nausea. Advanced stages may cause collapse, unconsciousness, coma and possible death due to respiratory failure.
Inhalation:
Inhalation of high concentrations may cause central nervous system effects characterized by headache, dizziness, unconsciousness and coma. Inhalation of vapor may cause respiratory tract irritation. May cause narcotic effects.
Chronic:
Prolonged or repeated skin contact may cause defatting and dermatitis. May cause allergic skin reaction in some individuals.

Jeff ( Brimble ) am I correct in thinking your putting gg3 into your
Backpack or trolley and mixing it with pure water ? If so,what dilution
Rate.? I agree with DJW here on this `Isò`business.The dilution rates
That NHW is using it at all but beggars belief.Yet he `swears`by it !
Jeff Brimble is`nt exactly `jumping up and down and dancing on the
Table`about it.I know one thing,it ruddy well stinks ! At this time,I
Spent £2 for liter of it.I`ll try anything once,but unless I`m doing something
Wrong I`ll be putting my next £2 towards something else.Hope though
That NHW can persuade me otherwise.

Hmm, maybe you should think twice before spraying the stuff into the air and breathing the fine mist that you can get if the water bounces off the glass.

to put this in perspective
if you got sprayed with beer down the pub would you run home to shower ???
ever drunk neat spirits ???
effective,or noticeable if you question effective,dilutions are as low as 0.05% by volume
if you are worried about fire hazzards try pouring a can of special brew on your daughters dolls house
now chuck a lit match at it ::)
get the idea
put 250 ml in 500 ltrs and you could drink 5 pints and pass a breath test
