Next project on the clean up in our house was the bathroom cabinets, drawers, and under sink. Again I took EVERYTHING out and threw out what was old or not used. Wiped out with a damp cloth Then put everything back.
We have tile walls in both bathrooms so while Harrison is taking is bath from time to time. I will shut the door and not turn the fan. Once it gets good steamy I wipe down the walls, it works great.
