Suppose I have a small kid that had two cans of slime jelly (a Jelly made of water, glycerin, thickeners, dispersant, flavorings and pigments).
And that two cans were inside a backpack, and somehow opened and spread in the bottom. Involving some dolls, small toy cars, entrancing in some holes. Even after trying physical processes not all jelly could be removed.
Adding water and soap did not difference, as jelly is still there, and even the two colors haven't mixed.
How can I dissolve those jelly, preferably leaving the nylon backpack, the metal cars and the plastic dolls without significant damage?
