I am a window cleaner by trade. A customer asked me to powerwash the exterior first two floors of his building, which I started to do. He wasn't happy that the powerwashing wasn't producing a noticeable difference so I went out and bought a restoration chemical called "Hydroclean 626". Some of the wall was a dark pink/red shiny granite and I tried a small area with this chemical. It looked great, so I continued to use the chemical. But the problem was, I didn't wait for it to completely dry. When it dried, it turned white. Now I have a problem. Is there a way that I can restore the 100 square feet of granite that is now white? Thanks for any help.

 

Dear Sheldon:

Oh boy!!... :-(

I really don't think that I have good news for you, but before I make any sure assessment I need to see the MSDS of the chemical you used.

Then we'll take it from there.

Ciao and good luck,
