Restaurants are locations where cleanliness is at a premium. Whether restrooms or tables or the kitchen, having areas that are free of contaminants leads to a more welcoming and safe dining experience for customers, engendering trust and possibly loyalty. A single statistic can back that up.
29% of respondents to a survey said they’d never go back to a restaurant that had unsanitary bathrooms.
Cleanliness is a big industry, with revenues approaching $170 billion every year around the globe. And while traditional cleaning methods like sanitary spray can be effective, the advent of steam cleaning has led to the possibility of a new heightened rung of cleanliness, for both the food service and other industries.
Unsafe food can be caused by three main contaminants. Biological contaminants include microorganisms. Chemical contaminants include cleaning solvents and pest control. Physical contaminants include dirt, hair, or other matter.
Steam cleaning systems have been shown to be incredibly effective at eliminating nearly all of these contaminants. It works by heating tap water in a boiler to high temperatures. This releases a steam that is low pressure and low moisture. This steam:
- Kills 99% of household germs like E. Coli, salmonella, and staph.
- Kills bed bugs up to nearly two and a half inches long into a gap.
- Eliminates chemical residues while leaving the treated surface “mess free”.
There are many versions of steam cleaners, such as industrial steam cleaners, industrial steamers, commercial dry steam cleaners, and others. Here are some important points on how these systems work, as well as a another powerful option to try.
A central part of a steam cleaner is the boiler. After tap water is put into the boiler, the boiler heats the water up to temperatures as high as 310 degrees Fahrenheit. This produces low pressure, low moisture water vapor that can be used to sterilize inanimate surfaces. The level of moisture in the vapor is roughly 5% to 6% water.
Another option within this field is a process called dry ice blasting and uses specific dry ice blasting equipment. Dry ice blasting involves using dry ice, which is the solid form of carbon dioxide, to create a pressurized air stream in order to clean surfaces.
Dry ice blasting equipment accelerates the block of dry ice, propelling pellets (which are very light) at the surface that needs to be cleaned. While the pellets themselves are so light that they cause minimal abrasion, some think that the change of the dry ice into a gas creates microscopic shock waves that clean the surface.
Dry ice blasting equipment uses either a one-hose or two-hose delivery system. While two-hose delivery systems have benefits in the cleaning of more delicate surfaces, one-hose delivery systems are more widely used today, especially when more aggressive cleaning is needed.
Steam cleaning and dry ice blasting can be effective forms of cleaning, posing minimal risk to surfaces and doing away with many, if not most, contaminants.
