Aquaphor or A&D cream.
I use/have A&D cream right now and the one time she did get a rash it made it go away pretty quick

Vitacilina I’m not sure if I spelled it right but it works wonders

Also, corn starch

Aquaphor

I use Balmex, it works wonders because my son sweats and that helps when he breaks out in a rash

I prefer aquaphor

We use Triple Paste Diaper Rash Ointment. I apply it on at night and it usually clears by the morning.

We also change her diapers often. So she has not gotten a bad rash. Once it turns red and irritated i bust out the ointment and slather it on her 😂
