Using ox bright on a garage, left white blotches... help?

I sprayed ox bright to remove the rust and now I’m left with these white blotchy patches everywhere… any idea what to do next? I’ll have a pick soon when it dries, I tried rinsing it off.

Photos?

What material was the rust on?

Smooth concrete. I dont have pics yet.

It lightens concrete so you have to do the whole area or at least from control joint to control joint. You can also try and lightly mist around the edges to gradually blend or fade it in. Being a garage floor you might just want or have to do the whole thing.

Or, did you do the whole thing are still have white blotches? If so I bet some areas are smoother than others and it didn’t penetrate as well. If so, maybe spray some more and try scrubbing it in with a deck brush. If that doesn’t do anything I wonder if you might be able to lightly etch it with a very weak muriatic solution? That’s just a thought so I definitely wouldn’t go there without someone like @Racer or @gbattle chiming in.

Problem solved, yes I had to do the whole area. The garage was a bit un level and had areas where it settled. A bit of brushing helped. Thanks guys.
