Removing styrofoam insulation from inside freezer walls

They should take it wirth the insulation still on it. They will adjust the price though. what they do to the price depends on how well they know you, and how much they like to take advantage of people in general.

I would call and find out. If you have a contact there, talk to them. I would find oiut pricing before you put in too much effort. Everyone has a different value on thier time, and at the right price it might be better to sell it whole.

Sprayfoam can be a pain, and using chemicals on it may make the mess worse, or even make you sick. My guess is a VERY sharp scraper of some kind.
