I have just started in the Pressure Cleaning Service in my area. I will NOT use bleach on ANYTHING. What I use is biodegradable materials that I can get locally, cost is between 6 & 8 dollars a gallon. Sure, more expensive than a dollar gallon of bleach, but in my opinion, bleach will do more harm than good. It will, after time, destroy the wood, vinyl, etc. Some potential customers are wondering why other PWers are using bleach and only charging $50 on a Look, you guys that use bleach can continue if you desire. I am going to take the HIGH road and use what I feel that most customers would prefer . . . a REAL cleaning job . . . not just a blast and give me the cash! Integrity people, Integrity!! We have to answer for what we do.
