Bona Stone Tile and Laminate Cleaner Refill Cartridge 850ml 3 "Great Cleaner but not so great cartridge" Reena 21 August 2020 This product leaves my tiles nice and shiny and very clean. The smell isn’t really detectable. I purchased the carton to refill the cartridge with but the problem is as you spray the cartridge kind of collapses in on itself making it quite useless to refill as it becomes a funny shape. It’s a shame the cartridge doesn’t retain it’s original size and structure so it can be reused. As it crumples up it then doesn’t sit in the mop properly. If it weren’t for this fault I would give it 5 stars.
