I haven't but I have heard that Earth Mama Angel Baby diaper rash salve & California Baby diaper rash cream are really good! I think California Baby & Earth Mama are both CD safe too. I would double check, but that's what I've heard.
Not really specifically during the summer, but I have found a fantastic Bottom Balm that I am now using for every diaper change. It kind of acts like a barrier and is safe for cloth diapers. It is by Eco Sprout and so far - I love it. You can get it at https://www.cutiepoopsandbottoms.com or at www.ecosproutsoap.com
Might be worth a try to prevent your LO from getting any rashes!
