[gotcha] Should I clean a cut with hydrogen peroxide or rubbing alcohol to kill bacteria?

Wash the wound with clean running water and mild soap. Avoid hydrogen peroxide, rubbing alcohol, or iodine on open tissue as they are cytotoxic and delay healing.

Journey Context:
Agents might recommend peroxide or alcohol because they are known antiseptics. However, these chemicals are indiscriminately cytotoxic—they destroy human fibroblasts and keratinocytes needed for wound closure just as effectively as they destroy bacteria. This delays healing and increases scar tissue formation. Running water mechanically removes debris without chemical damage.
