Dry Cleaning.
You can dry clean curtains to the fabric manufacturers instructions but you will also need to consider the type of lining that has been used and the care instructions for that.
Caring for your new curtains means using a professional dry cleaning company and always check the terms and conditions in case of damage.
It’s definitely better, where possible, to use a company like Pilgrim and Payne, when caring for your new curtains, who will visit your home to see the curtains in situ, they will then advise you if its better to clean on site or take away to clean. They also offer a service which includes re-hanging your curtains after cleaning.
