I founded FLAT CAT GEAR, designed and manufacture the Multi-Fuel Stove; this deal is only available to Backpackinglight readers ($5 off), limited time offer, yada, yada, yada.
It takes the proper stove design to burn isopropyl alcohol without generating soot or smoke. The key it to adjust the stove for the right air to fuel ratios. The benefit to isopropyl alcohol is probably the cheapest, safest and most readily available form of alcohol. It also has a high energy density: Isopropyl – 12,900, Ethanol – 11,700, Methanol – 8,419.
This offer is being made to help convert those of you who think that isopropyl is a dirty fuel. The stove is made of Stainless Steel and weighs 33 grams. Â Click here for the link to the offer.
We spent year developing the Multi-Fuel (ISO-Clean) stove and consider it a fair weather stove. Below 35 F, it can be difficult to light, additionally, above 5,000 feet the output drops off. Even though the energy density is high, the stove burns slower than a comparable denatured alcohol stove. For larger pots, the stove works best with 91% rubbing alcohol, for mugs 70% is ideal. 99% and HEET in the RED bottle can be used but must be watered down.

We call it the Multi-Fuel stove as it will also burn denatured alcohol, gel alcohol, hand sanitizer, Sterno and yes you can burn Esbit in the stove. While being a Multi-Fuel stove, the fuel efficiencies are not as comparable to a stove dedicated to a single fuel and this stove will consume ~25% to 50% more fuel.
