Belly button piercing advice

So 2 weeks ago I had gotten my belly button pierced and I would like some advice because I have been cleaning it really good everyday with the sea salt body piercing spay that the piercing shop had given me and its doing fine but there is that like dry crud on the piercing it’s self and I would like to know if that’s normal for that to happen I only have one other piercing which is my nose and I didn’t experience dry crud on the nose piercing as I have with my belly button piercing I would like to know if that’s normal
