Innovative and unique mix of sodium bicarbonate and sodium carbonate (soda crystals), sequicarbonate is a multi-purpose, economical and very effective household product. It is often used as water softener in regions where problems linked to hard water are widespread. Added to the laundry, it increases the efficiency of detergents or soap. Sequicarbonate is a Borax substitute, which product has been forbidden because of its dangerousness. It substitutes sodium percarbonate to remove stains at low temperatures. There are other possible uses for this product: copper cleaning, delicate textiles washing, cutlery washing, swimming pool maintenance or even in the bathwater, for a feeling of well-being.
