The First Step to delete a product is to make sure the product that you desire to delete is not attached to a Store.
If so, the first step is to go to the store. (PS do not delete the store with products associated with, you must first remove the products from the store before deleting the store)
Click on the "products" tab and remove the product from the store that you want to delete .
Now that you remove the product from the store, you can go back to the "Product" module, select "Actions," and press delete.
