WASHING SODA / SODA ASH / SODIUM CARBONATE

Washing soda, also known as sodium carbonate, soda ash, or soda crystals, is in the same family as baking soda but has been processed differently. It has a much higher alkalinity, with a pH of 11, which helps it act as a solvent to remove a range of stains. While it doesn’t give off harmful fumes, you do need to wear gloves because it can cause skin irritation.
