What substance should generally be avoided for cleaning a wound?

Hydrogen peroxide is generally avoided for cleaning wounds because it can damage the tissue and delay the healing process. While it is effective at killing bacteria due to its oxidizing properties, it doesn't discriminate between harmful pathogens and healthy cells. This can lead to additional trauma to the wound site and potentially increase the risk of infection or complications during the healing process.

In contrast, normal saline solution is often recommended for wound cleaning as it is gentle on tissues and helps to flush out debris without causing cellular damage. Antiseptic wipes can be useful, although it’s important to choose ones that are suitable for sensitive skin and wounds. Soap and water is also a common and effective method for cleaning wounds, as it helps to remove dirt and contaminants without interfering with the healing tissues.
