OXO Good Grips Extendable Tub and Tile Scrub 5 "Not just Tubs and Tiles" CELIA TRUMAN 20 November 2018 This is excellent for shorter people to get to top of shower tiles. However it is a brilliant and safe way to clean the windows of my potting shed. They lean inward and I have always felt nervous standing on steps to lean in and clean in case I fell onto the glass. Now it’s a a doddle just standing on the ground.The textured surface easily removes the green build up. I then used it to clean the PVC window sills. It would be excellent if they made an interchangeable soft head for drying and buffing. Will be ordering a second one so I have an indoor.outdoor choice.
