Go to Google.com or your Google home page (click photo to make larger):
On the right side, click on your picture or login (click photo to make larger):

Scroll down to bottom and DELETE YOUR GOOGLE + PROFILE (click photo to make larger). When I deleted the profile, I was sent to a "Aw Snap Error Page". Disgusted, I checked my profile, and the Plus was still there. So I quit the Chrome Browser Application, waited 30 minutes, and went back into it. My profile was all clean:
