Okay, so I know how much bleach and water and I've decided to give it a go...but now I need specifics and advice.
First, how do I apply the solution? My siding is rough and the area to clean is quite large. Do I use a brush? Will it damage the siding and paint/stain? Do I use a sprayer? What kind should I use and can I rent it or do I have to buy it?
Second, do I need to protect my windows and doors in any way? Obviously, they are exposed to rain, but I'm nervous about getting bleach on them and spraying water at higher-than-rain pressure.
Third, is this a terrible time of year to do this? Would I be better off waiting for drier days? I live in the Northeast, where humidity is a problem all through summer. The autumn has drier air, but more rain. I'd rather not be going through the same process in a year or two, having promoted mold growth by wetting the siding in high humidity under a porch roof where the sun won't dry it at all.
Fourth, would I be better off hiring a professional powerwasher? I'm only worried about damage to my rough siding. I hate the rough siding, but replacing it is NOT in the budget.
Thanks for your help!
