CAUSES: Selection of a flat finish for areas subject to heavy wear and soiling. Repeated spot washings using abrasive cleansing powder rather than liquid detergents. Furniture or other objects rubbing against walls of other painted surfaces. Dark colors show more.
SOLUTION: Paint high traffic areas with high quality, washable semi-gloss or gloss finishes. Do not clean with abrasive cleaners. Wash with non-abrasive detergents with a sponge or soft cloth and rinse with clean water. Gloss finishes and easier to clean and resist soil.
