 Once you break that barrier, you want to make sure stuff doesn't get in it. So you want to wash it out really well. And you can use just regular tap water. That works the best. We use it in the hospital. But wash it out well and then put a clean dressing on. Absolutely. And you talked about some of the things maybe to watch out for when it comes to purchasing these at-home care products. But how do we know maybe when at-home care maybe isn't enough and obviously when it's time to maybe go see a doctor about an issue?
