The EPA recommends two drops of 8.25% sodium hypochlorite solution (regular, unscented chlorine bleach) mixed per one quart/liter of water and leave to stand covered for 30 to 60 minutes. Two drops of 5% solution also suffices. Double the amount of bleach if the water is cloudy, colored, or very cold.
Bleach activation is also known as perhydrolysis. Persalts are inorganic salts that are used as hydrogen peroxide carriers (examples include sodium percarbonate and sodium perborate). Persalts and bleach activators are included together in powder laundry detergents that contain bleach. In the wash, both compounds dissolve in the water.
[44] [45] It may be made by diluting household bleach as appropriate (normally 1 part bleach to 9 parts water). [46] Such solutions have been demonstrated to inactivate both C. difficile [44] and HPV. [47] "Weak chlorine solution" is a 0.05% solution of hypochlorite used for washing hands, but is normally prepared with calcium hypochlorite ...

Sodium hypochlorite (NaClO), usually as a 3–6% solution in water, usually called "liquid bleach" or just "bleach". Historically called "Javel water" (French: eau de Javel). It is used in many households to whiten laundry, disinfect hard surfaces in kitchens and bathrooms, treat water for drinking, and keep swimming pools free of infectious ...
Calcium hypochlorite is an inorganic compound with chemical formula Ca(Cl O) 2, also written as Ca(OCl) 2.It is a white solid, although commercial samples appear yellow. It strongly smells of chlorine, owing to its slow decomposition in moist air.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Despite the relatively low solubility of TAED in cool water, (1 g/L at 20 °C), the granulate dissolves rapidly in the washing liquor. The peroxyacetic acid formed has bactericidal , virucidal and fungicidal properties, thereby enabling TAED with percarbonate to disinfect and deodorize .
