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.
