I have put a contact form in my blog. Is there any way to remove where it says:
Never submit passwords through Google Forms. Powered by Google Drive
This content is neither created nor endorsed by Google when I go to the form.
I think this link might give a possible solution http://shibulijack.wordpress.com/2012/03/02/how-to-remove-powered-by-google-docs/
You can't. The form is embedded from Google and it automatically adds those bits. If you don't want them, use a different form service - though any "free" form service will add links or ads.
