How to Unblock a Drain Using Caustic Soda?

How to use caustic soda for cleaning & unclogging drains?

Take a large bucket and dilute 3 cups (750 ml) of caustic soda in 3 litres of cold water.

Use a wooden spoon or stirrer to mix the soda and the water.

Do not use these containers and utensils for any cooking-related purpose later on. Also, avoid using your hands to stir the mixture.

As you mix up the two, you should see a bit of fizz and some amount of heat.

Now pour this solution straight drown the blocked drain and let it sit undisturbed for 30 minutes.

Now boil 4 litres of water and use it to flush the drain.

If the block persists, you can repeat this procedure a couple of times. www.bdsdrainage.co.uk Call: 02036 757 174
