If you notice a stain in between cleanings, spot treat it by spraying window cleaner directly on the affected area and gently wiping it with a soft cloth. You can also rub each slat with a dryer sheet after each cleaning.

Dip a soft scrub brush into the cleaning mixture and gently scrub each slat.
