Daily use is the clearest part of this question to answer, because repeated use is exactly what the advice is written against.
For an open surgical wound, do not use skin cleansers, alcohol, peroxide, iodine, or soap with antibacterial chemicals. These can damage the wound tissue and slow healing. This isn’t about how often. It’s about using it at all.
For pressure sores, the advice is the same with one exception: do not use hydrogen peroxide or iodine cleansers unless directed by your provider, as they can damage the skin.
Being directed by your provider is the only route to using it. A provider directing a particular use for a particular wound is a different thing from a daily habit started at home. There’s no advice for using peroxide on an ongoing or routine basis.
It’s worth being plain about why this feels backward. Peroxide foams on contact, and the foaming looks like proof that something is being cleaned. The point isn’t that it does nothing. It’s what it does to the tissue that is trying to heal.
What to use instead is plain by comparison. Mild soap and water for a stage I pressure sore. Salt water, also called saline, rinsed to remove loose dead tissue, for a stage II. Normal saline or mild soapy water for an open surgical wound, gently dabbed or wiped on with gauze or a soft cloth.
Wound Wizard has a separate page on using hydrogen peroxide on a wound at all, which covers the one example of a surgeon directing its use. This page is about repeated use, and on that, the answer is clear.
