For anyone in Australia who is interested, i got in touch with Ellie from Gold Street Studios who put me onto this stuff that she's been using for years: https://www.chemsupply.com.au/al048-2-5l-p

I'm in Australia and was following this thread to find Denatured Alcohol here.
I think the link above is broken, but searched their site and found this, which I believe is what was linked to: https://www.chemsupply.com.au/absolu...n-uhdpe-bottle
@guywithacamera - any other tips on where to source chemicals, aluminium plates or other wetplate related bits in Melbourne/Australia?
FYI, I (and many others) have found that the choice of alcohol is much less critical than what some want to make us believe. I successfully use generic bio-ethanol (around €2 per liter) which is something like 96%. Anything above 96% purity is problematic due to two reasons: fractional distillation is theoretically and practically limited to a purity of 96% because alcohol and water form an azeotrope, meaning that the remaining 4% water cannot be removed by distillation and additional 'drying' must take place, making the product much more expensive. The second problem is that 100% alcohol will not remain 100% due to the hygroscopic nature of ethanol. Simply put: the alcohol will absorb moisture from the air and over time, an opened bottle of 100% ethanol will automatically transform itself to an azeotropic 96/4 ethanol/water mixture. But most importantly, I personally found (and like I said, so did many others) that the small fraction of water isn't a problem for wet plate applications. Any generic 96% denatured alcohol will do just fine, as long as no colorants etc. have been added.
I thought the azeotrope was more like 85/15 alcohol/water, but it’s been a very long time since I had to know. I was going to say some dentaurants could be an issue, but the more I think about the less sure I am. I guess I will point out that there are several such mixtures involving toluene, Methanol, etc., and for consistency you might want to get the same kind each time.
Or this stuff, which is similar:

I don't use that particular brand but something that is likely equivalent; 95% bio-ethanol. Works fine as far as I can tell.
Thank you. Much appreciated.
