Pro tip: To declutter thoroughly, make one pass through your bathroom and then go through and declutter again. It’s surprising how many things you didn’t discard on the first pass that you’ll be ready to discard on the second pass.
As you empty each space, clean it. The most effective way to clean cabinets, shelves, and drawers is to use a canister vacuum to suck up all the debris and then wipe the area with a rag and all-purpose cleaner. After you’ve put everything away, clean the rest of the surfaces including countertops, mirrors, fixtures, toilet, bathtub, and shower.
