I feel that American companies try too hard marketing their stuff to buy refills and whatnot including printers. Well, for Swiffer dusters out there, you don’t have to keep buying refills if you on a budget, try this Swiffer bottle hack so you can refill with Mr. Clean and water instead, practically the same thing for a lot less.
Drill a 5/16″ hole in the top (when upside down) of the bottle. Hot glue a 5/16″ nut around the hole you just drilled. Once cool, insert your 5/16″ bolt into the hole. We refilled ours with half Mr. Clean, half water.
