Remove Global Product Option

I have created a global product option but it wasn't coming up properly so I deleted it however it continues to appear and when I go to the options list, it no longer shows up as an option. How can I get rid of it so it no longer appears?

Maybe clear the cache and browser cache then check again

Thank you for responding. I've cleared both the browser and cart cache but the problem seems to prevail. I can delete the option in each product individually but with over 500 products it's a very time comsuming process.

I see, so the option wasnt applied as a linked option then.

You can deleted all though the database by running an sql query that someone smarter than me here could probably supply.
