Whats the best chem to clean this? And where can I get some?

I'd start with strong NaOCl you can get it a a chem dealer or pool supply,..and lesser strengths just about anywhere.

Sodium Hypochlorite 12%, mix it half water and half 12%. Use a pump up or a dedicated pump to apply. Add a surfactant to the mix and it should clean it up with light pressure.

Thanks guys, that's my house wash mix only a little hotter.

Yep - I usually start with a house wah mix and then a light rinse - maybe 1000psi. Then use about 6% mix and leave it. It will look as close to perfect as possible within a few minutes.
