Can you use Saline Solution for contacts on your lip piercing?

Not a good idea. The saline soultion contains other goodies to keep your contacts in good shape and these little add ins will cause you grief with your navel piercing. Just use warm water in the shower to irrigate the piercing before you exit the shower. That should be good enough, too much fussing can cause trouble, treat it like a cut on your finger and it will heal just fine.
