This washing soda (sodium carbonate) refill can be used to remove stubborn stains from laundry and it is an essential component in most homemade laundry detergent.

The sodium carbonate "softens" water helping other cleaning ingredients lift dirt from the fabrics and suspend it in the wash water and allows the detergent to be absorbed into fibers properly to clean clothes.

Not to be confused with sodium bicarbonate (bicarbinate of soda).


Sodium carbonate
