My surgeon said to keep it dry and covered while it was healing.

Yes! My surgeon had this felt-like "fabric" that i would cut to cover the opening, then cover with a clear adhesive bandage. The "felt" kept he would with the right amount of moisture to heal and absorbed the draining. I think it also had some antibiotic in it. Ask your doc about that...it really worked for me.
Sorry, the "felt" kept the right amount of moisture in the wound for optimum healing, but also absorbed the draining...
