Terry, I'm in the minority here and well, the rest of the internet....my climate and marketing favors a sodium hydroxide chemical. One thing to remember, your not cleaning asphalt, your cleaning a surface of compressed ceramic granuals. BUT in your climate you may wish to favor the standard sodium hypochlorite and tsp blend. Just don't claim to go by the ARMA method if you're not doing it to the 'letter' best of luck and welcome to a world of never ending fun Share this post Link to post Share on other sites
