Washing Down South

I’m looking for some cleaning/washing products for the girl downstairs that won’t really mess up my pH balance or any of the good bacteria. I’ve used Summer’s <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> but I just feel like I need something better and I know water and dove soap would be fine but it just doesn’t seem to work the best for me. Any suggestions are appreciated!
