How can one dissolve Borax crystals that have adhered to glass and metal?

My daughter and I have had fun creating Borax crystal formations by dissolving Borax in warm water, inserting a sponge medium then allowing evaporation to crystallize the Borax to the formation.  However, both the glass vase and non-stick cooking pot that we used now have Borax crystals strongly adhered to the surface - to the point that they cannot be scraped away.  So far, we have tried soaking in vinegar to no effect.


I'm hoping there's an obvious solution that we can apply to simply dissolve the formed Borax crystals.
