Using a turbo nozzle on house washes is a BIG NO NO. No offense to Jonathan, but he is giving you some VERY BAD advice on how to wash home exteriors. Chemicals are a pressure washers best friend. They allow you to achieve the best quailty results with the least amount of muscule. In general, if you have to use anymore than 1000 psi to wash a house, you're not using the right chems, period. I rarely have to use more than 500 psi to rinse anything I wash, with the exception of cleaning concrete. The idea is to use high gpm with a moderate amount of pressure, let the chems do the work and make life easier for yourself.
As for chlorine being dangerous, it's only as dangerous as the idiot who's using it. If you use the right dillutions, and keep the vegitation and anything else that can be affected well rinsed, before, during, and after cleaning each section you will not have any problems. I buy my chlorine from a local Pinch-a-Penny for $1.10 a gallon, if I had to pay $13.50 a gallon for a supposed mildew cleaner that doesn't even work nearly as well as chlorine, I would probably go out of business.
Jonathan,
I highly suggest you do some searching on this bbs and some of the others to research better, faster, more cost effective ways to clean. I don't mean this as an insult your just working a lot harder, and probably with inferior results than you need too.
Just to through some questions out for you:
Why would you think that sodium hypochlorite is such a bad chem to use?
What is the active ingrediant in the mildew busters you use, and do you have a copy of the msds?
What chems do you use to clean the black streaks off of gutters?
How long does it generally take you to clean an average 2,000 sq ft house?
Eric,
An x-jet is a very effecient chemical application tool. Its a nozzle that can pull chems up to as much as a 1:1 ratio. It can shoot chems and rinse up to 30 or 40 ft. depending on your machine. It's almost a must have for many reasons.
