I have used Jomax on my home. I followed the instructions on the bottle and it worked great. Spray it on, wait couple of minutes, spray it off. I got some (not on purpose) on some bushes up against the house and it didn't affect them at all. Of course I sprayed the bushes down with water real well after spraying the walls down. I didn't scrub once, I don't think there is anything easier to clean siding. I have vinyl siding and have heard that using pressure washer is not good b/c the water will get up under the siding when spraying upwards at the high points. Jomax just washes off with a hose.
