SH is completely safe,..and is one of the most used products in the World. In regards to your current product,..if you have to get really close and clean every square inch with pressure,..then it's not working,..you are. If you're gonna be afraid to use the most accepted practices you may as well hang it up now.
What are you using to clean the stripes from gutters? How about rust?,..What about heavy dirt stains that can be 3-4 pieces of siding down from the soffit on homes that may have never been cleaned? Products that come in pouches and then added to water isn't gonna clean much at all in the real World of exterior cleaning,..especially if you want happy customers.
This is knowledge you need to set you on an equal playing field with those who know what they're doing,..albeit,..they are few and far between in the PW business. Which knowing the proper methods will then set you above those clowns.
In a nutshell,..Ralph pointed you to the better mousetrap already,..if you refuse SH and soap,..you're gonna be all alone on this board and may want to go to one of the "Eco" boards and listen to their blabber.
Seriously though,..after a year in business it's time you learn more about proper cleaning,..you need to spend many hours on this board reading.
People who bash bleach usually do it for a couple of reasons:
(1) They have a product they want to sell
(2) They want to use it as a selling point to gain clients,..usually in a last ditch effort to survive in the business by going "Green"
(3) They're plain stupid
