Apparently, one of my children had a piece of taffy in their pocket when I did the washing and now I have taffy stuck in my dryer! It is stuck on the side and I can't get all of it to come off.

Any suggestions?

Might try holding an ice cube against the taffy until it becomes really brittle. At that point you can shatter it - since it's be nearly frozen. I've done that with chewing gum and think it should work here as well.
Hope this helps!

WD-40 is my "remover of all stuff nasty" in the dryer. Then you have to clean it with a good degreaser to get that out!

Since taffy is mainly sugar, and disolves in your mouth, I would suggest a damp sponge or towel after the big chunks are gone; unless the heat from the dryer has turned it to black carbon.
