What ointment or treatment is good for diaper rash?

My one year poops after every meal, causes diaper rash. It’s red, a times his skin bleeds in tiny spots. I use everything from Desitin to Powder, but nothing seems to work. I also changed his diaper brand, but nothing.

What kind of diaper rash ointment can I use with cloth diapers?

So far, my youngest hasn’t broken out in a rash from wearing cloth diapers overnight with plastic pants. In case she does, I want to know what kind of diaper rash ointment to use. Is there a cheap brand that clears up rashes and won’t ruin the diapers? I know Desetin isn’t good for cloth diapers because it makes them stinky.
