Step 3 : Cover the container with microwavable lid . Do n’t apply Al foil .
Step 4 : Poke some holes on top of the lids so that steam can escape .
footstep 5 : Heat the potting grunge at full power for around 90 second .
Step 6 : After removing the containers from the microwave oven , cover the holes with tape measure .
