As said in multiple reports supressors and weapons go from pristine to damage in 1 or 2 mags which is annoying and unrealistic.
I suggest adding longer worn status and a new one, between Worn and Damage, named Dirty to all objects that can be fixed with the gun cleanning kit. This would allow the player to clean the weapon or supressor only using 1% of the cleaning kit. Using those objects while Dirty would result in an exponential damage on these parts
