How do you get dried duct tape residue off?

For particularly stubborn goo—and only on water-resistant surfaces—soak the item in warm soapy water, or cover it with a warm, wet, soapy sponge or rag, for 10 to 20 minutes. Then wipe dry, banishing the gunk as you go.

What will break down glue?

Dissolve water-based glue with warm, soapy water. Dip a sponge in the water, and then scrub the affected area until the glue breaks down. If the soapy water isn't enough, dip the sponge in rubbing alcohol and continue scrubbing. The alcohol breaks down the adhesive, causing the glue to dissolve quickly.
