Helix and nose help. How to clean. So confused and frustrated!!🥵🤯

I’ve been posting on here A LOT about the same two piercings I have, so I apologize for that. I live in a small town with no great piercers around me and I’ve been struggling with this big painful bump on my helix. I went to the local shop I got my nose done at to ask about it and they asked what I was cleaning with. I clean with saline wound wash. They told me that is not a cleanser and I need to be using dove sensitive skin soap to clean my piercings with. I’ve started using that morning and night and just go over my piercings with saline wound wash on a q tip after my shower or washing with the soap. For my helix I will add some diluted tea tree oil for the bump and for my nose I will spray some h2ocean spray on it. My question is, is the soap okay to use. This morning I noticed crust on my nose ring and it was peeling off so I just took it the rest of the way off the jewelry if that makes sense and it looked yellow. My nose piercing does not hurt and it seems to be healing fine, but I’m just concerned with the color. I’m not sure if this has happened before using the soap, I just started 2 days ago, but I’m not sure🤷🏼‍♀️ below is a picture of the crust.
