Yes, it is highly recommended to wash a house's exterior before painting to ensure the best results. Cleaning the surface removes dirt, dust, grime, mold, mildew, and old paint, which allows the new paint to adhere properly and results in a smoother, long-lasting finish. Failing to clean can lead to poor adhesion, peeling, and an uneven appearance. Pressure washing is an efficient method for this, but be cautious not to use excessive pressure that could damage siding or wood. For materials like vinyl or stucco, soft washing might be a better option. After washing, allow sufficient drying time, such as three to four days, before painting to prevent trapping moisture, which can cause blistering or peeling.

Power washing asbestos siding can be hazardous and isn't recommended. The power washer's high pressure can disturb the siding and release harmful asbestos fibers into the air. Rather than attempting to DIY it, hire a professional trained in asbestos handling to tackle any exterior cleaning.

Concrete does well with a number of cleaning agents, as it’s a durable material. Choose from acidic cleaners, alkaline cleaners, and pH-neutral cleaners, in addition to antibacterial solutions. Your best bet is to simply read the fine print with your preferred detergent and make sure it mentions concrete as a viable surface. 

Yes, you can safely pressure wash vinyl siding. As a durable material, vinyl can typically withstand pressure up to 3,000 PSI, holding up better than other siding types like aluminum or stucco. However, it's crucial to operate the pressure washer correctly to avoid damage. Before you begin, repair any existing cracks or damage to the siding. For a safe setup, use a 15- or 25-degree nozzle and maintain a distance of at least three feet from the siding to prevent splashback and damage.
