It is important that you maintain your weapons as they will accumulate grime from overuse or exposure to damaging environments. Sand, water, dust, and mud are just some of the weapon degrading substances that will cause your weapons to become less effective until if they are not cleaned become completely ruined.
Follow the steps below to clean a weapon.
Step 1:
