I got dirt in the circle button on my iphone. How do I get it out?

I have a black line of dirt all around my circle button on my iphone and nothing a tri gets it out and it looks bad cus it's a white iphone please help!

Try a toothpic. Maybe a pin.

Use a pin

Depends what iphone it is, if its an iphone 5s don't use a pin cause the finger print sensor gets easily ruined by scratching it with a pin, but if its a iphone 5, 5c, 4s, 4 etc. Then use a pin

Use slobber then pree it till you get onto Siri the carry on doing that
