Take a doubled garbage bag (or a reinforced box) and just start going through all items that need disposing of. Check for out-dated labels on condiments, or just old jars in the fridge that are never used. If you wouldn’t miss it, you don’t need it! If your drawers are hard to remove, try your vacuum wand to remove old onion skins (you know they’re in there!), and wipe out with a lemon or other grease cutting cleaner (yes, it can be natural, or just vinegar and hot water if you prefer).
Take a warm soapy cloth and give a quick wipe of your cabinet doors inside and out – especially the garbage receptacle one.
