Empty one area at a time
Start with a single cupboard or shelf. Wipe it clean, check for leaks and review the storage instructions on each bottle. Keep products that require refrigeration in the refrigerator.
Group by the task
Put everyday cooking oils together, condiments near their usual preparation area and reusable drinking bottles in their own section. A shallow tray can catch drips and make a group easier to lift.
Keep the system easy to maintain
Place taller bottles behind shorter ones and turn labels forward. Avoid stacking unstable containers. Leave a little empty space so putting a bottle back takes one movement.
