We rely on cleaning the floors of home tanks in Qassim by using detergents and removing dirt. We also use a mixture of cleaning agents, bleach, and hot water from a cleaning company in Qassim. We wash the sides of the water tank with a mop to remove accumulated dirt on the sides and corners of the water tank. Then, we scrub and rub the accumulated materials at the bottom and use dry disinfectants to remove rinsing water from the tank.
