I only use water, and occasionally baby wash if I'm needing extra cleaning for some reason. Anything beyond that stings me bad!
When I have just a general irritation down there (it's happened a lot over the last 6 months!), I usually use diaper cream/ointment of some type, whatever we have laying around. At the moment, we have A&D because we bought a big tube for the grandbabies. If cooling sounds like it would be helpful, there's a cream called "Calmoseptine" that you can get at mom-n-pop pharmacies (usually anywhere that would carry medical things for seniors, but not at places like Target or Walmart). It's a barrier protectant with menthol in it, and soothes, protects, and keeps the area feeling cool. I haven't bought a tube recently, but I remember loving it in the past when I would get irritated down there.
