If your Roman blind becomes marked or stained, first try to remove the stain using a clean, damp cloth. Gently rub the affected area with the cloth until the stain begins to lift.
To clean more greasy stains, you may need to try spot cleaning using a specialist fabric stain remover or gentle detergent.
If you ever need to clean mould off your Roman blind, brush with a stiff brush or spot treat with a specialist fabric detergent.
Always check that the product you are using is appropriate for your Roman blind fabric and make sure you follow the manufacturer instructions for removing the stain. Test a small, inconspicuous area of your blind fabric first if in doubt.
