Oxidation Removal?

[rj242 16]

I was wondering how any of you deal with oxidated vinyl. I have run across two houses this summer that had really bad oxidation. The one yesterday was battleship gray in the cedar shake style. I had to literially hit every square inch of it with pressure to get it clean. When I bid the job, I didn't realize that it was that bad, but when I started washing it, it started streaking up. What should have taken two hours ended up taking five hours.

good thing is you got it clean and the streaks were fixable...I usally add a little F-13...4oz to 5er.

Mud duck,

Does the 4oz of F13 remove bad oxidation? Being you are using F13, are you using simple cherry, and are you downstreaming?
