No. You need caustic to strip.

Caustic to strip and acid to netralize and brighten

Caustic or bleach for cedar siding?

Colt, FYI F9 BARC will remove those HCL acid burn stains and it contains no Hydrofluoric or hydrochloric. Much less dangerous to you. We have concrete coating companies using it because after they use HCL to acid wash concrete in preparation for their coatings it runs down the sidewalk. They use F9 to reverse the orange. It takes a very little amount too.

Might need to get some because that concrete turned back dark again then next wash when i put the caustic down

That F9 BARC sounds like a great product minus the hazard!

Exactly.. and it removes a full spectrum of stains. Now we are finding it works on removing 20 years of oxidation on glass too. More to come!
