Removing thinset from brick?
 

Hi there,
A few weeks ago my husband and I thought we were going to be tiling over part of a brick fireplace in our bedroom, so we put on a layer of thinset. I have since changed my mind and would like to just leave the brick fireplace alone. Is there any way to remove the thinset without damaging the bricks underneath?
Thanks!

Wire brush and muratic acid..
