My house is largely constructed with a Hardy Plank exterior. The paint on the north side of the house was quite visible with mildew, and the neighborhood association sent me a letter about either repainting or cleaning the siding.
I had to do this a few years back and found the job quite a bit of work. I purchased a product by Zinsser named JoMax. The instructions on JoMax say to mix with Bleach and water.
I had to use a vehicle brush and a ladder and do a lot of climbing and overhead work with the brush....but the JoMaxBleach works extremely well. The paint looks like new.
So....I decided this time around I might find a detergent that would work through a sprayer, buy the detergent, buy the sprayer, and make life easier.
Well, the Simple Green didn't work worth a $h#%. I followed the instructions to the tee. I reapplied because I found it difficult to believe it would not work. It didn't phase the mildew! So, I bought the JoMax and Bleach.
I also bought a 16' extension pole and and a vehicle wash head. It was a lot of work, but I was able to stay on the ground for most much of the work. I just mixed in a 5 gallon bucket and then applied by dunking the brush into the solution and slopping it onto the siding.
The new pressure washer made rinsing so much better. I have low water pressure at home, and the reach is poor with a garden hose.
So the verdict?
I wish someone would make a product that goes through the pressure washer that would kill and remove mildew without voiding the pump warranty. I read about bleach being harmful to the pump in my new pressure washer and so could not apply the JoMax solution in this manner.
Oh...and how does my house look? Like it was just painted! :)
PWD COMMENT: Thanks for the feedback. Yes, you shouldn't put bleach through a pressure washer. It will eat way the seals. You can, however, use the Campbell Hausfeld High-Pressure Soap Lance to spray the bleach. The detergent is stored in a bottle attached to the lance. You can actually spray the bleach under high pressure to reach second stories. A very nice product.
