Workplaces require water coolers to keep employees hydrated as they work. Many employees do not bring their water bottles to workplaces, making these water coolers the only source of hydration available. As these coolers are widely used across different levels in a workplace, it is essential to keep them clean at all times for pure water supply. So, here are some tips to maintain the cleanliness of office water systems: Cleaning the cooler It is essential to clean the cooler regularly to maintain its cleanliness and safety. A staff member should be assigned to clean the cooler every few hours to prevent it from becoming filthy with the frequent use by several people during the day. Before cleaning the water guard of the cooler, it must be unplugged from the main power supply. The bottle caps must also be punctured to dispense water into the cooler. Coolers usually come with a removable guard to make it easier for the staff to replace them. Cleaners must remove the guard and use small amounts of disinfectant to cleanse the various surfaces of the cooler. Hot water or a commercial bottle sterilization solution can also be used for cleaning. Paper towels help clean both the internal and external surfaces of the cooler.
