Problem discovered while using Specials

I have been having an issue with Zencart of deleted products still being ordered by customers even though they are not on the product list.
While using the Specials, I discovered that these items still appear in the list and I can click on them to bring up the page, even though they do not show in the Products list normally.

How can I get to these products to get rid of them once and for all? It is the list I have to scroll through far longer than it needs to be. My products change regularly so it is important that I can get rid of the old ones efficiently. Thanks
