Unfortunately I was unable to find a place to donate these bottles to be recycled again in Qatar and these had such a beautiful curves and texture. So I decided to turn them in something which I can display in my home.
First I soaked these in warm water with dish washing detergent.
It helped me in removing the labels but still there was some glue left.
I sprayed WD40 and waited for sometime. Than cleaned the bottle with soft fabric.
Now it was perfectly ready for any craft project.
