Bona Stone Tile and Laminate Cleaner Refill Cartridge 850ml 5 "Fabulous" Mrs Wright 22 March 2018 I bought the whole cleaning kit on a recommendation by a friend and can’t praise it enough. While I use their 2.5l bottle with a standard mop and water for whole floor cleaning, I use this beauty between the weekly clean to wipe away footprints, spills etc. It’s ridiculously easy to use, just spray and wipe. No smears, leaves floors gleaming. You need so little that the cartridge lasts a very long time. I’ve had the mop for about 8 months and have only just replaced the first cartridge.
