Is this efflorescence or something else? As you can see I used a power washer on a few bricks and it came off but I am currently looking into what kind of acid I can used to clean the bricks
Thanks

Is this solid masonry or is it a "Thin Brick" system?
Due to the uniformity of the appearance, that does not look like Efflorescence to me. It looks more like some sort of surface treatment added to the brick during the firing process or an acid treatment. These bricks have similar appearance...

I'm not sure what you are trying to clean. My suspicion is you've power washed the intended finish off of the surface of the brick. I would do some homework...
Try to find out what it's supposed to look like and how the manufacturer recommends you clean it before trying to treat it. And i would choose a more discreet test location next time.
