We had a maintenance man out at our rental home on monday. He used liquid fire underneath our sink to try and clear the line. He used a big kitchen pot of mine to catch the water from the water drain and it had caught the liquid fire as well. It was dumped out and rinsed out in my sink. I washed it today finally with soap and have thrown it out back but ky question is, is it safe to use a dish after being in contact with sulfuric acid. And second, i washed it with my hands and then washed my hands with soap and dried. There shouldnt be any reminents of it on me or on the other dishes that were in the sink after it was rinsed out and then those dishes washed, correct?
