how do I remove limescale from the tiles of my swimming pool without the need to drain out the water
Mr Clean Magic Eraser will remove lime scale without removing the water but will require some effort for the removal. There are several chemical products available, but most would require that the water be dropped below the area where the lime scale was present ,for efficient removal. There are also electronic removers that are available.
