What should the chlorine concentration be for sanitizing dishes?

The correct concentration for sanitizing dishes using chlorine is 100 parts per million (PPM). This level is effective in killing most harmful microorganisms when dishes are immersed or adequately rinsed with a solution containing this concentration.

Chlorine is a popular sanitizing agent because it is efficient, quick-acting, and relatively inexpensive. At 100 PPM, the solution remains effective for sanitization without leaving harmful residues on the dishes. It strikes the right balance, ensuring that the chlorine concentration is strong enough to sanitize effectively while also being safe for use on items that will come into contact with food.

Lower levels, such as 50 PPM or 75 PPM, may not provide sufficient sanitization, potentially leaving harmful pathogens that can cause foodborne illnesses. Conversely, concentrations higher than 100 PPM, such as 125 PPM, could pose safety risks, such as bleach taste or potential irritation for those using the dishes. Thus, the 100 PPM level is recognized as the optimal concentration for effective sanitation.
