I got the dreaded letter from my HOA that I was in violation of something new. This time, it was the driveway and sidewalks that were deemed dirty, so it was suggested that I pressure wash them. While I'm not a big fan of pressure washing houses or cars, as it can (I assume) create leaks or strip paint, I figured washing concrete was a DIY job I could handle. However, I needed to decide if a rental or a purchase was in order.
