Yeast/Diaper Rash what is it?!

Hi everyone.... My LO has had this since Sunday (EBF, LO had massive runs needless to say mom won't be eating spaghetti squash anytime soon again) we've been cleaning the area gently with warm wash cloths after every diaper change (the washer is working nonstop), and have used Balmex, Aquaphor and good ol' A&D but still the rash remains. Granted it is slightly better but it's still there. Anyone have any other recommendations? Trying out the "maizena" technique (it's a starch flour for cooking) to see if that works just a little worried it's taken so long. LO is also bathed everyday... 😢
