Deleted products not entirely gone

[blondedumbo]

Hi, I bought my website from someone who had loaded a heap of products before selling the site. I deleted the products as I did not have them. I did this individually, and also using the multiple products option.

These products no longer appear in the Catalog.

But when I go to Product Attributes or to Cross Sell Products, some of them are still there in the dropdown to choose them.

I cannot work out how to get rid of them.

I found images for some of them still on the server and deleted the images, but this did not get rid of them from Product Attributes or Cross Sell.

Could anyone please point me in the right direction on how to solve this?

Thank you in advance.
