I am not a chemist myself but I am trying to solve a practical problem I am experiencing.
I have a nicely working diesel stove but it produces some smell. I've read that adding urea to the exhaust may reduce the diesel specific smell? Is that true?
Also what other common (easy to find) chemicals can supress the specific smell of burning diesel? What about potassium permanganate for example? Is urea the best chemical to supress these smells or there are others which can do better?
