Adding disinfectants isn’t enough. The contamination usually settles on the walls. We have a simple technique. Follow our guide to easily clean your tank.
There are many disinfectants in the market, but nothing comes close to chlorination to disinfect and clean the tank.
Step 1:
Empty the tank.Clear the water through the outlet valve. Just make sure the water shouldn’t cause any localized flooding. Collect the remaining water with a bucket.

Step 2:
Clean the tank.Prepare a mixture of Surf Excel liquid detergent and baking soda, and sprinkle it on the walls of the tank. Using a bristle brush or abrasive sponge, scrub the insides of the tank. Move your arm horizontally from side to side while applying a good amount of pressure on the brush or sponge. Avoid brushes with steel bristles or sponges made of steel.
Step 3:
Rinse the tank.Use a water jet to forcefully get rid of the detergent and any other cleaning agent. Let it air dry.
Step 4:
Disinfect the water.After the tank is dry, refill it. The most common way of disinfecting a water tank is by chlorination. Add up to 100 gms of high-strength calcium hypochlorite (HSCH) to 1,000 litres of water.
