For most wounds, cleaning them once a day is sufficient. If you have a particularly severe wound, your doctor may recommend you clean it more than once per day. In some cases, you may need to clean the wound up to three times per day. Always check with your doctor before proceeding. Cleaning a wound too often when it isn’t needed can cause more irritation and slow down healing. When changing your dressing, you may also want to try applying a debridement gel underneath your dressing. This can help protect the wound and hydrate it at the same time, while also removing the bacteria that accumulates under a dressing.
