Sponge hazards

It’s a shame you did not explicitly state the possible dangers of microwaving sponges to kill germs if the sponges are not sopping wet [Jan. 29, “Nuke Those Sponges!”]. Your article did not take into account the fact that microwaves vary in their wattage and power. The nonmetallic wet sponges (with scrubber) that I nuked burned holes about the size of quarters less than two minutes into the process. I was left with a toxic stench and smoke that filled the room for a long while afterward.
