How do I remove white stains inside a tub?
■ White stains inside a dishwasher or on glassware are due to a chemical compound of
Calcium (Ca) or Magnesium (Mg) in water with detergent.
How to fix
1. For a dishwasher that can load 12 plate settings with a water softener,
please check hardness of water with a hardness cartridge enclosed with a manual.
2. Please set the water softener corresponding to the hardness of water.
(Please refer to a user's manual for more information)
3. To remove stains, put 200-300mL of vinegar(or 25g of citric acid) in a small container and place it inside.
Run a cycle without dishes.
