Tip #2 – To clean unexpected stains on vinyl windows and door frames (such as bubble gum, felt-tip pens, lipstick, motor oil or top soil), try using Fantastik® cleaner. For tougher stains (such as tar, pencil or oil marks) use Soft Scrub®. And, if children decide to draw on the windows with crayon, Lestoil® can often remove their creative efforts.
