Does SunJel Gel Fuel have a smell?

No, gel fuel doesn't put off any odor while burning. Terra Flame and SunJel has been making quality gel fuel for over 20 years and has always had great reviews from customers about being the only gel fuel on the market that doesn't put off a smell while it is burning. However, as with all gel fuels, there will be a slight odor when you open the lid. As soon as our gel fuel is lit, the fire will consume all vapors coming off of the gel and there will no longer be a smell.
