Try contact solution or saline solution.
I had the same problem with my industrial. first time I had it pierced it NEVER healed, even after 7 months and I was using the spray they gave me.
Then I heard about using regular contact solution and I decided to get it pierced again and it healed in 2 months. It was awesome!
BTW, you're NOT supposed to use Alcohol or soap to clean it (If you're washing your face and the soapy water runs over it it's okay).
