Pull it all out, zone it with a caddy and a tension rod, and add a motion light: tame the cabinet for good.
The cabinet under the sink is the Bermuda Triangle of the house. Pull everything out, toss the duplicates and the dried-up bottles, and wipe the base before a single thing goes back.
Line the base with a waterproof mat, then zone it: daily cleaners in a handled caddy, dishwasher and laundry extras behind, rubbish bags on a tension rod across the doors.
Add a stick-on motion light inside the door. Being able to see the back corner is half the battle won.
