Hey Ralph - It might be useful to know what the chemicals in the preservative were? What material is the cooler? Did they try anything yet?

I usually start with ethanol and/or ethyl acetate on adhesive residues.

Our biology department is cleaning out biological samples that have accumulated over about 20 years. Over the years, various non-formaldehyde based preservatives have slopped out of the containers into the cooler where they were stored, leaving a gummy residue behind on the floor of the cooler. I wonder if anyone has a found an effective way of removing this coating from the interior of the cooler?

Thanks for any advice about this.

- Ralph
