Just got back from a delightful couple of days hiking in the Cathedral Range in Victoria Australia, and I'm washing all the pots and plates, and cursing the black soot that comes off my Trangia alcohol fuel stove. Putting it through the dishwasher seems to have no effect, and it spreads to everything you touch.

Are there any pro-tips for removing soot or even better, preventing it? I'm running the stove on methylated spirits, which in Australia is ethanol that has a small amount of methanol Denatonium Benzoate, Methyl Isobutyl Ketone and Fluorescein added.

If unable to change fuel, as others have mentioned... as a youth I would spread dish soap (like dawn) over the outside of the pot (where the flames would hit). Then heat up my water/cook on a wood fire which would get the outside of the pot covered in soot. However, because of the dish soap, it came off easily during cleanup; and I would discover any spots I missed with the dish soap.

This is just a matter of what fuel you use. Some fuels burn cleaner than others. You may need to experiment a little bit to find a fuel that is available in your area and that burns cleanly. For example, I'm in California, and what I use is a certain brand of denatured alcohol that is sold as paint thinner at hardware stores.

The clean burning is a huge advantage of an alcohol stove, and it's the reason that I use one whenever I can. I only use a white gas stove if I'm going to be at high elevation and need to melt snow.

This is common with Trangias. I used to find the same in the UK when I used them. My miniature alcohol stove does the same. I've never found a way to prevent it occurring, though it can be made easier to clean off. Like you, I've never found a dishwasher to do anything to it, though any that doesn't come off with a cloth won't come off easily. A few drops of meths on a dry cloth may help get it off, saving your washing up water.

It's sometimes said that adding a little water to the fuel helps, though I've never been convinced. The cause is likely to be the denaturing additives rather than the ethanol itself - I suspect the ketone.

We used to wipe neat washing up liquid over the base of the pan after washing up. That made the soot clean off more easily.

Using the simmer ring makes things a little worse, as the flame from the jets is cleaner - but you'll need to use the simmer ring for long cooking or it will be too fierce.

When I was a Scout master we used to spread a thin film of dish soap all over the exterior of pans we used to cook on a wood fire (veeery sooty). Then washing away the soot required little or no effort.

Soot can be caused by the fuel in itself, or by an insufficient amount of oxygen in the flame. I don't know the model of your stove but maybe increasing the air content (i.e. burning leaner) may help.

I rub my trangia in sand on fresh water beaches at the lake. The sand takes the soot right of, slightly scratches the pan. It also seems to work to take sand into the hand and scrub the trangia with it but I have no idea what this does for the longevity of the gear. I think if you get fine enough white sand it should not be too abrasive

I believe, originally, the stove was meant to be used with methanol, which is no longer available to 'normal' consumers in many countries.

If methanol is used, it does not leave much soot on the pans.

If ethanol is your only choice, there is a trick that decreases the amount of soot in the flames:

Thin your alcohol down with water - you can add water, so the alcohol percentage in your fuel is down to 75% - I'd say go for 80%, maybe a bit more in cold weather.

This will decrease the amount of soot on your cookware, when using ethanol as fuel.

I agree, that it sounds counter-intuitive, but try it out ..

I was able to clean the soot / residue from a stainless steel kettle very nicely with Cif Cream Cleaner and a small cotton pad. However, it is not recommended for aluminum.

I don't know if there is an alcohol stove and fuel combination which would leave the pots clean.

Burn HEET yellow bottle gasoline water remover for automobile gas tanks. Zero anything while burning or residue on parts. Zero.
