After using your knife, it is a good practice to clean and dry your knife Even for blades that are made with corrosion-resistant stainless steel, prolonged exposure to the elements can cause the steel’s surface to oxidize. Folding knives should be kept clean of debris, particularly the locking device on lock-blade knives.
As an alternative, chemical solvents such as Acetone, nail polish remover, MEK, alcohol or paint thinner may be used to clean your blade. Use care with these solvents, as some, such as acetone, nail polish remover, white gas, or brake fluid may damage some knife handles. Avoid harsh detergents that contain Chlorine (mostly powders, including some for washing dishes and clothes), which can accelerate corrosion of the blade steel.
