My method:
1) Switch vented lid for a regular lid and place a small zoo med undertank heater beneath deli cup. I do this at night and by morning the ff's have been gassed and the media has more or less turned into a dry cake.
2) Tip the cup into a plastic bag and give it a good tap, contents usually come out at once, wrap and trash.
3)Put deli cups in bucket with bleach water, and wash w/soapy water after work.
Hint: do this the night before the trash gets picked up because in the So. Cal heat, trash will smell fierce
Oh yea, make sure lid (non vented) is tight fitting b/c quite a bit of gas gets produced. Never had a lid pop off yet, fingers crossed.
Hope this helps, Alex
