Using soap and water to get the majority of it up is preferred. However, if it is gummy, you may have some polymerization products of those preservatives that may cause you to move on up to less polar solvents, such as alcohols, acetone, hexane, etc.

I suspect that it's more related to the age of the materials; some of the samples are 20 years old. Faculty retirements have a tendency let to leave a lot of icky waste in their wake...
