Begin by soaking the bowl

Add Dish Soap

  • Pour around 240 g of dish soap in the bowl. The soap will lie at the bottom of the bowl since it is heavier than water. Allow the soap to rest in the bowl for about 25 minutes. The water level should go down during this time.
  • Pour more hot water gently, without letting it overflow. Repeat the process of adding soap and hot water, three times and inspect whether the clog has cleared. Ensure you leave the toilet to rest for 25 minutes before repeating the process.
  • By the first or second attempt your toilet should be unblocked.
  • In case the toilet fails to unclog, let the dish soap rest overnight. In case the problem persists, use a plunger.
  • Plunge the toilet while aiming at the toilet hole, at least five times. In case the clogged material fails to clear, add more dish soap and hot water then continue plunging till all debris clears.
