StealthFyre panels exposed to fire will become covered in soot even after one use if you are burning biofuels such as wood, twigs, and leaves. A quick and effective method for cleaning your stove is to use a common acid-based cleaner. This comes in the form of products like CLR or an automotive wheel brightener. Simply use the cleaner as directed and soak the panels for five to ten minutes, then rinse thoroughly.
A useful preemptive method of keeping your panels clean can be achieved by rubbing a very thin layer of liquid dish soap onto the surfaces of your panels with a dry cloth and allowing them to fully dry. This dry layer of soap will not burn away during use. But it will quickly rinse away in water, taking the soot with it. This will keep you from cleaning your stove as often.
