Now that you have decided a commercial/industrial pressure washer is what you need for your business, it is time to narrow down the choices again. The next decision to make is if you need a cold or hot pressure washer.
As a general rule, hot water will clean just about anything better the cold water. If you stop and think about our daily lives, everything we want really clean we use hot water – dishes, white clothes, carpet, even our cars at the carwash. Maybe, in your application though you don’t need it that clean so a cold water pressure washer is good enough. A cold water pressure washer can be equated to a penetrating scraper. They are great at removing loose paint, thick dirt, and mildew from concrete or siding. If you add soaps and degreasers in place of heat, they can be sufficient at jobs that would usually require hot water.
A hot water pressure washer is called upon to do the job for the toughest cleaning applications. Anytime oil or grease residue is involved, hot water is a must. Cleaning in the oilfield, on construction equipment, and removing oil and grease from concrete are examples of when hot water is a must; Also, situations where sanitation is a concern, for example food processing and restaurant kitchens. Cleaning vehicles that are covered with road grime and film is another example of when hot water cleans better and faster.
The frequency of your cleaning application should also influence your decision to invest in a hot or cold water pressure washer. If it will be a daily cleaning operation, we strongly recommend a hot water machine. Hot water machines not only clean better, they are also faster, thus reducing labor costs. If your cleaning operation will be intermittent and not involve oil and grease, a cold water unit should be sufficient.
These are a few of the factors that help you decide between a cold or hot water pressure washer. For more details in helping you choose the right system for your application, please contact the professionals a W.E.T.
