I just bought a chinese UV-C lightbulb and stuck it in a handheld lamp.
I put it in the cupboard for a 5-6 hours and shut the door. The ionized air that the light makes is supposed to disinfect too so it's more than just a line-of-sight effect.
It worked somewhat well as it doesn't smell moldy in there. Though maybe I should do it again just for good measure.
