It seems to be pretty easy to clean mold/mildew off my vinyl siding by spraying a bleach/water mixture and rinsing with a garden hose after a few minutes. I have been using an Ortho herbicide sprayer attached to the hose to spray and mix my bleach/water combo. This works great, but I can only get it to spray about 15 feet high. I have to get on a ladder to do the gables on my second story. Do any of you know anything similar that hooks to a hose that would allow a water/chemical mixture to be sprayed about 20-25 ft high? Is there something similar in concept to an x-jet that hooks on to a water hose that may have a little more range than an Ortho herbicide sprayer? I'm looking for a better alternative than spending a few grand to get a 4 gpm pressure cleaner to use once a year. I would hire someone, but I'm looking to save a few bucks if possible since this is so easy to do with the exception of getting on a ladder in very unlevel places.
