Disinfect your stainless steel container naturally with bleach
Bleach is an effective way of cleaning and disinfecting stainless steel gastronorm containers. To do this, simply dilute a suitable dose of bleach in enoughcold water, not hot water as you might think, as the corrosive properties of bleach combined with scalding water could damage your gastronorm tray.
Once the solution is ready for use, apply it to all surfaces of the gastronorm tray. Leave to stand for 5 minutes, then rinse thoroughly with a non-abrasive sponge or cloth. Make sure that the rinse is clean and free from traces of water.
This method can be very effective for cleaning stainless steel gastronorm trays, especially if you live in an area with hard water. However, it's important to remember that you shouldn' t mix this solution with chemicals or acids. The gases escaping from this mixture can be extremely harmful.
