Google Base Product Feed..deleted products, still have links

I have OpenCart v1.4.9.4 installed with Google Base Product Feed Module. Works great!

If I delete a product from my OpenCart database via Admin->Product List->Delete Product, how do I remove the product from the Google Product Feed? Currently there are a number of people who are visiting "old" links on my website because I am thinking that Google still sees these "deleted" products as active products. I am thinking that people are doing searches in Google and finding products that no longer exist in my OpenCart database and clicking on those links to visit my website.

I can log in to my Goggle Account and see that Google has 935 products for my OpenCart website/datafeed. I can log in to my OpenCart Admin website and see that I currently have 935 products enabled. I don't get it, how do I get rid of all the deleted product links that visitors are currently using to visit my website?

Any thoughts?

Thank you.
