What can I clean my lip piercing with on the go?

I got my lip piercing done today, well basically it was yesterday since it’s 2am Thursday but anyway. I am going out today(Thursday 26th) and like I was wondering what can I clean my piercing with on the go.

Like my roommate got his lip piercing and he told me the day after he went clubbing and the smoke in there slowed his healing process down. So he told me if I am going to clubs, just clean my piercing asap.

So I thought I might bring along some cleaning solution with me but the thing is I don’t know what cleaning solution I can use for the outside of my lip on the go.

Does anyone know what I can use on the go to clean my lip piercing on the outside(preferably also inside) and is sort of small like I can put it in a pocket or purse?
