RE: Softwashing Chemicals

In 2011 we also want to offer house washing.  There seems to always be a slightly different mix contractors are using I guess depending on the homes exterior surface like vinyl, aluminum, wood, or brick.  Does the different surfaces change the best ingredients & mix to use? 

I also see some are using their pressure washing pumps while others are using their air diaphragm pumps injecting downstream.  If you had both pumps available what & why use one over the other?

Hi Steve,..I have both available on every job,...I wouldn't even consider using the air-diaphragm over the pressure washer. The pressure washer allows for a simpler method,...downstreaming.
There is another thread on here stating the reasons why. Just search softwashing and you'll find the info about it and then you can choose on your own which will suit you best.

Jeff is absolutely right. There are way to many factors to consider when doing an exterior wash. One of the biggest I've run into is the exterior paint. Many times there is no way of knowing whether or not the customer has used a quality paint or if they used a cheaper paint. Applying chems directly to the surfaces will sometimes pull the pigment out of the paint and in some cases even change the look.  DS'ing with a Pressure Washer makes those factors pretty much go away.

The only time I will use my Roof Cleaning pump to apply chems is either if the mold and algae has advanced to the point where I need the extra chems to defeat it or if we are preparing a house or building for painting and the infestation is extremely sever and calls for it.

We have been giving a House Bath,we down stream with the pressure washer (orange simple green) smells good,more bubbles than a car wash,everyones happy using a detergent nozzle on the wand. Especially good for grime,mud daubers,clingy bugs. We wet down one side then come back and rinse before it drys. No plants killed and leaves the house shining. I will often walk the area first with a hand pump of SH mix and get  moldy areas that the detergent would not get on its own.
