Sodium Carbonate: The Ultimate Household Cleaning Powerhouse

When it comes to effective, eco-friendly, and affordable cleaning solutions, Sodium Carbonate stands out as a top contender. Also known as washing soda or soda ash, this simple inorganic compound has been trusted in households for generations. With a chemical formula of Na2CO3, sodium carbonate is a white, water-soluble powder with strong alkaline properties, making it a powerful cleaning agent for a wide range of domestic tasks.
In this guide, we’ll explore the science behind sodium carbonate, its many household uses, how to use it effectively and safely, and why it’s a must-have in any eco-conscious home.
What is Sodium Carbonate?
