You should clean the curtain by shaking and sweeping it on a weekly basis. So don't worry as the Green Cleaners team brings you the best curtain service in Brisbane. Cleaning your curtains regularly helps remove dust, allergens and odors that your curtains absorb. That's why you have to wash them by hand or during the washer. To really freshen up heavy clothes, you'll steam them. How you choose to wash your curtains depends on how heavily you want to wash them and the type of material your curtains are made of. Lace and sheer fabrics will require gentle cleaning while heavier materials can be washed just like regular clothing.
