Scrabble is a game that is played by 2, 3 or 4 people. It uses a board with squares on it (15x15) and a large number of letters on small tiles. Each player, when it is his/her turn, has to put a word on the board, using any of the seven letters (seven tiles) that they have in front of them. Their word must join on to what is already on the board.
Install a water softener in your home. Hard water contains dissolved calcium, magnesium, lime and iron. Use water softener salts specially formulated to remove iron from water and prevent rust stains in bathtubs, sinks, toilet bowls and laundry. These water softener salts often go by the names of Rust Out, Red Out or Iron Fighter Pellets.
Edit Answer (for another -15 minute) I have had the system for a couple of years. I am leaving it in place as a very expensive filter and installing a water softener at the discharge of the system. The reason: can not clean surfaces enough to keep the stains off any surface the water touches.
