ELI5: How exactly does my pickle jar still smell vaguely of pickles after several trips through the washer?

Basically the way soap works is that it forms molecular bonds with a lot of sticky and food type molecules. These bonds are generally stronger than the bonds between food and skin, or food and glass. Then when you introduce hot water to the situation you're adding energy, which is used by the molecules to jump from the weaker bond to the stronger one.

So why doesn't the vinegar brine of pickles leave the glass? Because the bond with soap isn't strong enough. Dried vinegar forms a very strong bond with glass, so it has to be physically unbonded (pushed off with enough pressure) not molecularly unbonded (chemically sticking to the soap).
