Worst product. No use at all. There is no effect even after pouring one full box in the drain.

Very bad product

Value for money and it worked

I tried using caustic soda to clear a blocked drain, and it worked very well. First, I boiled about 3–4 litres of water. Once the water was hot, I carefully mixed in 4 tablespoons of caustic soda. Then I slowly poured the solution into the clogged sink drain and let it sit for around 15 minutes. After that, I flushed the drain with fresh water. The blockage was completely removed, and the water started flowing normally again. This method is quick and effective, but it should be handled carefully due to the strong nature of caustic soda.This is not a paid review:)

Before opening the bottle, keep yours hands or gloves dry, as they react instantly. Use a mask, they create a pungent smell. Pour boiling water, for tough stains and clogging. Handle with care.
