Your Fire Set doesn’t need much cleaning or long term care. Make sure to keep the ferro rod and striker clean of any dirt, grease, etc. that could hinder the ability to strike and spark cleanly.
At WG, we typically get 20-30 fires out of a single pack, however the exact number will depend on your firemaking experience and the conditions. In summer when it’s hot and dry, you can get away with using a smaller amount. If your kindling is saturated, you will want to use more.
Spark Fiber is made from the pulp fiber of American White Pine, which is a byproduct of sustainably managed logging operations on the east coast of the USA. The pine pulp chips are virgin and are reclaimed from the timber industry. The chips are cooked in a pressurized vessel which naturally sterilizes them with steam to remove any pathogens that may exist. The fiber is then dried and packed.
