Granulation on c section incision - silver nitrate

ETSS 🖤

I’m 18 days post op and just went it the OB for what he said was granulation and he burnt the fleshy bubble thing off with silver nitrate. However I don’t recall him telling me how to care for it. Do I just use water in the shower like I’ve been doing? I was using peroxide on the granulation beforehand too. Anybody also deal with this?
