Using or rubbing alcohol to clean an injury can actually harm the tissue and delay healing. The best way to clean a minor wound is with cool running water and mild soap. Rinse the wound for at least five minutes to remove dirt, debris, and bacteria. I don't think the answer of number 8 is isopropyl alcohol.
ReplyDeleteIf isopropyl alcohol is not the right answer then what should we use when we get harm? Formalin? Kerosene? Acetone? The no. 8 answer is based in real life situation.
