How to remove Magento custom order status

magento, magento-1.8

Solution

There are no way to delete the custom order statuses from Magento admin but you can delete it from Database tables

sales_order_status
sales_order_status_label

Problem

I've added new order status in the Admin Panel. I need to remove it, but I can't find option like that. Is that possible to do it without the database viewing?
