Can you guess what this chemical is for cleaning wood fence?

Hmm? The second and third are definitely using bleach. The git in the second video says it right out. The third video seems to be bleach as well or a sodium percobinate before staining. No clue what the first guy uses to clean that wood fence but I would definitely like to get my hands on some. I've never seen bleach clean up a wood fence like that. Interesting!
 
I spotted a jug of clorox in the second video.

The first video was excellent. Especially the line "the pressure washer will break your fence over time". The rabid dog was a nice touch also.

Yea I bet the dog was sick after that.
 
I have tried bleach before and it never did anything like in those videos, I did try diluted but not straight. Hmmmmmmmmm

It's gotta be straight.
 
I wonder what chemical out there would be good to spray on grass at the fence to protect it as that will be a lot of bleach being sprayed onto the fence?
 
I saw that first video awhile back. I called the number and it was no longer good.
 
After watching the videos, do you guys think the wood would need a brightener on it to look better?

I was thinking that this would be a faster way to make old, gray fences look great again faster than pressure washing but it would probably be a good idea to rinse the wood when done.
 
A fence thats been baking in the sun for ten years wont look brand new just by putting bleach on it. It might take the grey off but it wont look good. it will be blotchy.
 
If I were to guess I would say it is bleach that is actually mixed WAY stronger than necessary for cleaning. Any stripper will darken the wood, not lighten it. Precarbonate bleach usually leave an inconsistent look especially when dry. Looks like good old chlorine bleach. Anybody spraying that strong a mixture near grass or anything will be pissed. If these guys were so smart they wood have a roof cleaning set up in there truck and knock out the fence in minutes. I always brighten after using bleach, bleach is a base just like a stripper just not as high up on the alkaline chart. There are other reasons for using a brightener, especially oxalic acid. One, it not only neutralizes wood tannins but also iron, rust, and metal stains in wood. On fences this make a HUGE difference in a quality job by removing these stains. Secondly, it works quickly and you get a good idea how the end result will turn out and how well the surface will look. Third, oxalic acid helps open the pores of the wood helping with penetration of your coating.
