Wiping your window treatment down and getting rid of dust will most likely be all you regularly need to do. To dust, use a clean, dry cloth or a feather duster. Using a polyester cloth creates static that can attract dust, so sticking with cotton or microfiber cloth will give you better results.
In the case of some products, you can do a spot cleaning, but please check below for the specifics and whether that product is okay to spot clean. If so, use a dampened cloth. Do not use a cloth that’s dripping wet! You can also add a small amount of mild soap or detergent, if needed.
WARNING: You should not immerse any part of your blinds, shades or shutters in liquid. Using harsh chemical solvents can damage the components.
