If you’re the cleaning crew, you might be wondering why the boss is having you have to practically burn yourself as you wash dishes, counter tops and equipment. Is scalding water necessary or can it just be warm?
Well, the boss might be onto something. In general, higher-temperature cleaning solutions result in better cleaning. Many soak and manual cleaning methods work best at 120°F or 130˚F (50°C to 55°C). Many spray washing techniques work best at 140°F to 160°F (60°C to 70°C). A good rule of thumb: the cleaning speed doubles with every increase of 20˚F (10˚C).
So, the hotter you can stand it, the quicker the job is done. Also, don’t neglect temperature on the rinse. Rinsing can be done at slightly cooler temps — room temperature, warm, or hot tap water.
