    Right, i normally get my Isopropyl Alcohol from a chemical supplier near work, but they have gone the way of bureaucracy and now need a purchase order from an OH&S authorised source for any purchases, and so i cant buy over the counter.

    Previous to that i used to buy the IsoPro stuff from DSE, but at $8 for 25mL its a bit rich, especially as $5 used to get me 100mL.

    Does anyone know any other sources?

    I purchased mine from bunnings, near the glue supplies if I recall correcly. It comes in a little 125ml pump pack bottle and I forget the price, it wasn't too expensive though. It is 100% Isopropynol - the brand is Diggers.

    Isopropynol or propan-2-ol?

    A lot of the "rubbing alcohol"s and cheap IsoPro is propan-1-ol which does nasty things to ABS, and especially shellac, which goes gummy and gluey.
    Really need propan-2-ol.

    Isopropyl alcohol is propan-2-ol - if it says isopropyl alcohol, then that's what it is.

    Of course shellac dissolves in alcohol - it dissolves in basically any alcohol, and most organic solvents.

    :rolleyes: That's not helpful at all. If you don't know who sells it and who does not, why bother to post? Jaycar, for example, does not sell it.

    In the US Isopropyl Alcohol is normally propan-1-ol, not propan-2-ol. Now this causes issues with various plastics as well as shellac. Which while it will dissolve in both propan-1-ol and propan-2-ol it turns into a nice white gummy substance with propan-1-ol but not with propan-2-ol. A chemist could probably tell me why, but from what i know its hell to clean off boards and more importantly leaf shutters.
    Hence why im picky about getting propan-2-ol.

    The other problem with Isopropyl Alcohol in any form is that its a restricted travel substance, and so costs a bomb to transport. Hence its worth finding local places. Altronics used to be my source when i was living in Melbourne, but there arnt any Adelaide locations.

    I think this is around $10 for 100% Isopropanol (Isopropyl), 125ml. I use it slightly diluted with distilled water for cleaning LCDs and cct boards, works a treat.

    Due to the chemical nomenclature of the "iso" prefix, isopropyl cannot be propan-1-ol. Anything labelled isopropyl should be what you're looking for.

    Good luck with your search, though.
