What's everyone using?

Wonder what the magic chemicals are that people are soft washing fences with in you tube videos that instant brightens. Percarbonite?

Potash

Nice!

What is Potash? I’m totally oblivious but im New and interested

Instant brightness would have to be strong SH mix which isn’t good for the wood.

I know this, but that’s not what they are using and I’m trying to figure it out and know one is talking.

Caustic potash. Basically lye soap but in flake form. Raw form of what most deck strippers are made from. Also called sodium hydroxide.

Thanks man! Been busy; sorry for the delay. Greatly appreciated.
