It is simple and safe – you can easily do it at home!
Plaster of Paris (calcium sulphate) is not soluble in water. Extensive research has given simple solution for dissolving POP Ganesh idols in water using ammonium bicarbonate (Baking Soda).

Step 1

Take a bucket in which the idol can be fully immersed. Fill it with water and add ammonium bicarbonate powder weighing approximately same as weight of Ganesh idol.


Remove Nirmalya and other decorative items from the Ganesh Idol. Then immerse the Ganesh idol in the solution prepared in the step 1.


Gently stir the mixture in the container every 2 to 3 hours. In approximately 48 hours, Ganesh idol will get completely dissolved. Sludge, that settles at the bottom of the container is calcium carbonate.

Step 4

The liquid left is ammonium sulphate which is a popular fertilizer and can be used as such, for watering plants and lawns.

Be a part of the solution!
Let's celebrate an eco-friendly Ganesh Festival!!!

starThis eco-friendly process can be implemented for idols at home and at the mandals.
