Remove it from the database is the only sure way. If you leave it in the database and there is a link to it somewhere it will be possible to order it. You could use inventory tracking to prevent it from being actually ordered but it could still be placed in the cart.
If you need to keep the product info you could use the Copy function to make a copy of the product and then delete the original.
