Since I was trying to make some marshmallows for the first time, I bought liquid glucose as was mentioned in the recipe. But, because of mishandling, the cap off the plastic container was not closed properly by me, and I kept it in a storage cupboard as it was. Now somehow it fell inside the cupboard and spilled inside it. It has now jammed the cupboard door. The problem is that it continues to spill and will soon waste the whole lot.
How can I dissolve this liquid glucose in order to open the door?
