Make your own!
White King Ultra Water Softener & Detergent Booster® is getting awfully hard to find -- as reflected in the price these sellers are demanding. Fortunately, you can make your own. The WhiteKing® box does not state the ingredients, but no problem. Poison Control has the ingredients list and toxicology reports for everything an American could possibly misuse.<br />  WhiteKing Ultra Water Softener & Detergent Booster® is approximately two-thirds Sodium Carbonate and one-third sodium tripolyphosphate. Amazon sells both chemicals in bulk.<br />  Try adding one tablespoonful to your dishwasher. It works wonders.
