i am softwashing my fence using a 2% mix with Green wash. as i began to softwash it i notice a hint of orangish brown coming off the fence. Upon further inspection of my fence i noticed it has this white crumbly stuff all over it. if i scrub it with a brush it seams to come off but would take all day. do you all think that is some type of paint or other coating thats coming off. I am not the one that had the fence built so i do not know if the previous owners put a coating on it. Could it be the pressure treated wood from home depot? what went wrong?
Not sure as wood is very different from job to job. Sometimes we use a 3 or 4 percent mix on really nasty wood. There is a process and something like that I would do a test spot to see results.
