    Old concrete

    Hello All. My South Florida, concrete, three car driveway, is now twenty five years old, and looks it. After all the twice a year cleaning, the concrete is somewhat pitted. My usual session is no longer removing, what I guess to be, a build up of dirt and grime in the pits. I have only used my rig (DeWalt 4200 psi, 4 gpm pressure washer, and AP+ 21" surface washer) to this point. I never got in to pretreating, or using detergent. That's due to the various, and often conflicting recommendations, that I've read each time I've researched. I never came to a workable conclusion in my mind. I'd greatly appreciate a coherent solution, from a knowledgeable person, if you have the time, and thanks in advance. I'd like to read a full description of what I should do at this point. Specific equipment. Detergents and pretreatments. And method and technique. I'f needed I'll purchase a downstream injector and the like. Cleaning twice a year is enough, the last cleaning stayed just four months. Thanks, Steve
