how to remove a wrong url-domain association

[scorpion]

What's the quickest way to remove an error in google's crawl, that is a wrong URL is associated with the correct website, should you just remove the wrong domain name from your host's DNS server and then run a remove link, or wait 30 days for google to detect a 301 redirect to the correct URL in your .htaccess file (seems kinda slow..)

IMHO, I suggest you to resubmit your URL to google at [google.com...] I think it will come to your new site faster.

For everything to appear in google, the fastest is to wait until next update.
