1) Yes, regular freezer bags (ziploc) work fine, and boiling water works good in them.. second on trailcooking.com and look for "FBC" or "freezer bag cooking" recepies.

2) really really.. you don't need soap.

When not freezer bag cooking, usually I just scrub out my pot with sand and/or rocks and rinse, and lick my spoon clean.
