    Even after draining out all the water from the tank by the taps, there is still a reasonable amount of water left below the exit pipe of your tank which you have to take out manually. Read the next step. If small enough, just turn it upside down and drain through the access manway.

    Now it is the time to get in action. If its a smaller tank, it may be possible to use a NEW mop and a bucket of dish washing soap, brush all interior surface areas, drain the tank, rinse and drain, then rinse and drain again. No residual soap is your goal.

    Keep a big bucket outside. The person inside the tank will fill the small bucket and give it to the person outside, who will empty it in the big bucket.

    Soon the water level will be so low that you will have to follow a different strategy. Now use a large rough cloth which preferably absorbs water. Let the cloth absorb water and squeeze it out in the small bucket to fill it.

Tips

  • Wear rubber gloves (to protect your hands from soap) and swimming goggles (to keep the soap out of your eyes) while cleaning the tank.

Warnings

  • Do not let a claustrophobic person enter the tank.
  • Take care that the dish washing detergent solution does not come in contact with your skin or eyes. Mostly it causes minor itching but if it should harm you more than that, get medical advice.
  • Beware of the rusted iron pipe endings inside the tank. Tape the ends before starting the cleaning process so they can't severely hurt you. If you get hurt by one, seek medical advice immediately.
