>>647320You say HEET is "worse" than 90% isopropyl or denatured... Could you elaborate? Exactly how do you think it's worse? In my experience denatured is pretty good but insanely expensive and 90% isopropyl absolutely SUCKS compared to HEET. 90% Isopropyl takes longer to come up to priming temperature, blackens the bottom of your cooking vessel and when it burns out, it leaves this nasty water residue behind. Depending on you stove type (soda can - water bottle) this leftover water can be very difficult to remove and if NOT removed, it will contaminate your next fuel load, lowering it's percentage and exacerbating the negative effects I listed above. HEET, on the other hand, quickly comes up to priming temp, burns hot and clean and has a beautiful blue flame (pic related)
