Hot water pressure washers for cleaning and disinfecting large surfaces

The intensive and meticulous cleaning with pressure washers offers the possibility to achieve a high standard of hygiene. They can be used to reach places that are difficult to access manually, such as crevices and cracks. They are especially helpful when cleaning and disinfecting large surfaces such as ceilings, walls and floors and can effectively combat germs, bacteria and viruses.

High standards for hygiene

The intensive and meticulous cleaning with pressure washers offers the possibility to achieve a high standard of hygiene. They can be used to reach places that are difficult to access manually, such as crevices and cracks. They are especially helpful when cleaning and disinfecting large surfaces such as ceilings, walls and floors and can effectively combat germs, bacteria and viruses.

The use of hot water pressure washers speeds up cleaning by up to 40 percent compared to cold-water units, especially due to the faster drying of the cleaned surfaces. In addition to better results and a faster cleaning and drying time, a measurable reduction of germs can be achieved when using hot water pressure washers and a water temperature of at least 185°F. Not only dirt, but also bacteria and viruses can be effectively fought. With the help of the steam stage it is even possible to clean at temperatures of up to 311°F. 

Depending on the cleaning application, the water pressure and quantity of water can be regulated at the pressure washer gun. This makes it possible to work with the appropriate combination in each case without the dirt splashing back and coming towards the user.


Using cleaning agents to interrupt infection chains

When cleaning with pressure washers, suitable cleaning agents should also be applied with the cup foam lance to distrupt infection chains and remove all dirt residues. Cleaning foam is so stable that it adheres to surfaces and increases the time and cleaning effect. The subsequent rinsing with water helps to remove the dirt in a controlled manner and to prevent renewed contamination. Biodegradable cleaning agents can also support the process.

After cleaning with high pressure

After meticulous cleaning with pressure washers, a subsequent disinfection rounds off the cleaning process (see instructions for disinfection with pressure washers): Soak, clean, allow to dry and finally disinfect surfaces.

To remove dirt and residual water, a wet/dry commercial vacuum can effectively support the work of the pressure washer.
