It's not just the inside of a house that gets dirty. Exterior siding can accumulate a lot of dust and grime, even mildew. And because siding is the face we offer the street, even a little dirt shows.
Some houses naturally accumulate more dirt than others.
If you live along a dusty road or in a new development where lawns are not yet established, you can expect a daily barrage of grit and grime. Textured siding or peeling paint only compounds the problem. When dirt really settles in, the only remedy is a good cleaning with a pressure washer or a scrub brush. We prefer a pressure washer because it's a lot less work. While cleaning is the focus here, pressure washers also have long been used in paint prep.
