Ethanol instead of Methyl for dry bleaching?

[thefizz]

I have done bleaching of dry prints with iodine, thiocarbamide and methyl alcohol but I'm finding methyl very expensive to buy now, so I'm wondering if ethanol (which I already have & much cheaper) would work?

If you already have some ethanol, you are in the best position to answer your question... by trying.

I sure am but I'm wondering if there would be any negative effects over time of using ethanol, hence my question.

Ethanol is the stuff you drink in beer & scotch etc, so I doubt if you could breath in enough or absorb through your skin to do any harm. Actually I'm kind of surprised you can buy it in pure form!

Pure Ethanol can be obtained over here locally in pharmacies. The problem with pure Ethanol however is the vast liquor tax on it which makes the gross price about 15fold.
Thus I'm surprised to learn that in the US Methanol is more expensive.
Most probably the OP is refering to denaturized Ethanol.

Yes I think what I have is denaturized Ethanol and I was wondering if it would have any negative effects on the print?

The best substitute in general for Ethanol is Isopropanol. Pure, low toxic, no liquor tax issue.

i'm interested in trying this out, especially if it is of low toxicity, where can I find more info on this technique?

It's used for localised bleaching of dry prints.

From one of Tim Rudman's books:

Sulution A
Iodine 2.3g
Methyl alcohol 50ml

Solution B
Thiocarbamide 4.6g
Methyl alcohol 50ml

Mix A and B 50:50 and apply with a cotton pad. After a short time, wipe away with another pad dipped in alcohol only. It will dry quickly and be ready for another application of bleach if required.

thanks, thefizz. Just out of curiosity, which Rudman book?
