I'm searching for fuel availability for alcohol stoves. From what I understand, ethanol > 70% is "banned". I've read that hardware stores and large supermarkets sell BBQ starter fluid, some of them being > 90% ethanol. Is that so? Suggestion?
@Stéphane Gauvin Banned from where? In Australia we can buy “Methylated Spirits” which (these days) is almost 100% ethanol but with bitterant added to make it undrinkable. Restrictions on ethanol usually are made to restrict its human consumption, hence adding bitterants. Tony
@Stéphane Gauvin alcohol for drinking is very rarely sold at above 50% ethanol (100 proof in US, 87ºproof in UK) and typically more likely 35 to 40% As @Tony Press stated at higher concentrations it's usual for ethanol to be adulterated with methanol and / or bitterants and frequently a distinctive coloured dye. It may be different in Canada and that would explain why a lot of Canadian stovies use methyl hydrate instead. Interestingly, 70% ethanol is what I was taught to use when wiping down work surfaces in a microbiology lab before and after experiments as that's the concentration that causes cells to rupture.

So, the problem seems to be a ban on denatured alcohol in Canada. Methyl hydrate (methanol, methyl alcohol) would be one way to go. Just noticed that marine stove fuel (equivalent to denatured alcohol) might be available in Canada.
@Stéphane Gauvin Ethanol is available in Canada. It is sold as Bio Ethanol Fireplace fuel. Type "Ethanol Fireplace Fuel Canada" into your search engine and you will find numerous sites like this or this that sell pure ethanol in Canada. Ben
In my opinion this whole 'denatured alcohol is banned' business relates directly back to California's ban on its use as a solvent. Marked and sold as 'stove fuel', or just 'fuel', it remained available. We discussed this here at CCS a few years ago. What California does, eventually other places follow-- not in banning denatured alcohol, but in labeling it 'stove fuel'-- because the Cal market is so large. So now in Washington we have the absurd situation of the stuff labeled as 'fuel' (with denatured alcohol below in small letters), and sold still among the solvents, not the fuels. It's not 'banned' here, and I have my doubts it is in Canada....
I have trailed some metho from an industrial cleaning supply mob here. Msds sheet says it’s 99-100% ethanol. There’s bitterant in it but not listed. Burns wonderfull in pressure stoves and with water very good in trangia burners. Given the flick to diggers brand for a while. Finally have a win with stove fuels here. Well a drop of kerosene goes along way and still smells respectable, but wouldn’t use it cooking with the Omni oven type set-ups. You might have to look at popcorns still’ in licker with a badger’s pecker. Something like that.
Isopropyl alcohol no good in stoves? It seems that's cheap over there, cheaper than ethanol at least from what I've gathered. It's pricey as here in Aus Don't they sell methanol or ethanol as widescreen washer fluid for winter use due to it not freezing? The availability and different prices is funny between countries. Shellite/naphtha/white gas is so expensive here I started distilling unleaded. I gather it's pretty cheap over there comparatively
Isopropyl alcohol is not a stove fuel. Ethanol and Methanol are both stove fuels. Ethanol is biodegradable and less toxic than Methanol. Ben
Isopropyl didn't work well in a Trangia. I don't remember the percentage I tried but it wasn't good. Around here there's a product sold as gasoline line antifreeze called Heet, and it's either methanol or isopropyl depending on the formulation you buy. The methanol works great and is very inexpensive if caught on sale at the end of the season. Maybe something similar is available in other countries. The use case for gasoline antifreeze largely disappeared with the introduction of 10% ethanol fuels, but thankful it's still available for camp stove use.
We use 70% isopropyl alcohol in our Micro lab, but same difference. I believe that concentration is more easily absorbed into the cells and then rupturing them.
