Our diffusion fabrics are not designed to be cleaned. Iron, hard water, softener salts, and anything out of the tap can stain diffusion fabric. Chemicals from cleaners can also weaken the material and alter the neutral color characteristics of the fabric. If absolutely necessary, you can try hand washing the screen with a delicate soap diluted with distilled water and allow to air dry. Results cannot be guaranteed. Always check that the fabric is completely dry before storing.
