What steps should be taken to remove any duplicate items from the list?

To remove duplicate items from a list, you can follow these steps:

1. Create a new empty list to store unique items.
2. Iterate through each item in the original list.
3. Check if the item is already in the new list.
4. If the item is not in the new list, add it.
5. Continue this process for all items in the original list.
6. The new list will now contain only unique items.
