Vaseline on cloth diapers?

My daughter had an issue in her diapering area that we were using medicine for, but now that it's cleared up we are advised to use Vaseline to keep it from returning.
We were told by our pediatrician no cloth diapers for a while due to the issue, but it's been at least a month now. We still have to use the baselinefor longer though.
Can I use Vaseline on her with the cloth diapers?
I don't have Facebook.
