Cold room cleaning: how to clean without switching off the refrigeration and when to disinfect

Why cold rooms are hard to clean

With the cold room running, washing water freezes and ice builds up on floors, shelves and evaporators. Switching off the refrigeration to clean means emptying the room, uses energy and lengthens downtime. What is more, cold and humidity are the conditions in which Listeria monocytogenes keeps growing, which is why cold rooms are one of the points the cleaning plan monitors (see Listeria).

According to its data sheet, Freez Clean works at temperatures down to −25 ºC, removes its own volume in ice and, used regularly, prevents ice layers from forming and helps to save energy.

When disinfection is needed

Freez Clean is a cleaning and hygiene product. When the cleaning plan calls for disinfection of the cold room (for example, during a deep clean with the room shut down), Bacter Clor is a disinfectant with registration number 18-20-06676-HA that its data sheet recommends for cold rooms, as well as abattoirs, cutting rooms and canning plants: it is applied at 2–5% at room temperature, left to act for 5–15 minutes and rinsed off with water under pressure. It complies with UNE-EN 13697 against Listeria monocytogenes at 2% under dirty conditions.
