Mould and bacteria control

Mould and bacteria thrive in a moist environment. During the cleaning process, we remove mould, bacteria and contaminants from drains pits and vessels. We chemically treat food and beverage drains and pits to protect them from mould and bacteria regrowth.

Qualified Coolclean technicians

Our Coolclean technicians carry specialist equipment to perform work efficiently, to minimise impact on your operation. Our technicians are fully trained, and HACCP qualified to safely carry out the work.

Environmentally friendly cleaning

Avoiding the use of cleaning chemicals in food related areas makes perfect sense. As part of our standard clean, the food-safe biocide is environmentally friendly, pH neutral, non-corrosive and fully biodegradable.

Improved food safety and product shelf life

Mould and bacteria thrive in a moist environment. This builds up naturally on cooling units, walls, and ceilings.

Drains and pits can act as prime incubators to spread mould and bacteria via foot traffic over drain surfaces and throughout walkways. Moulds and bacteria can produce contaminants that degrade food, cause illness, and reduce shelf life.

Coolclean provides protection from mould and bacteria, to assist in keeping food production areas hygienically clean and suitable for food storage.
