Firearms (excluding hand grenades and planted explosives) can be maintained by using either a '''Gun Cleaning Kit (GCK)''' or a '''Gun Repair Kit (GRK)'''. GCKs can only be used if the firearm's Condition is 60% or higher, whereas GRKs can be used on any firearm, though they are more expensive.
One use of a GCK will increase one firearm's Condition by 100 200 + [[Repairing#Repairing skill levels|skill bonus]].<br/>One use of a GRK will instead increase one firearm's Condition by 250 400 + [[Repairing#Repairing skill levels|skill bonus]].
It is advisable to keep multiple kits of either type if you wish not to rely on the maintenance services of a workshop.
All melee weapons (excluding those with a max Condition rating of '''N/A''', as they neither degrade nor need to be repaired) can be maintained by using a '''Melee Repair Kit (MRK)'''.
One use of a MRK will increase one melee weapon's Condition by 250 400 + [[Repairing#Repairing skill levels|skill bonus]].
