I just checked on a 25L bag it was 14$ (cad). Why bother it is a compostable material and isn't very costly? I am sure it could be washed and sterilized (baking it or microwaving you would have to check the times) but by the time you spend the cash and energy to do so you would have a new bag. I have never bread snakes (yet next season) But I know my breeder I deal with tosses it out.
