How do you clean dirty fireplace brick?
Dirty as in dusty? Or dirty as in covered in soot?
I had tried cleaning a brick fireplace before, so I didn’t even try when we moved. I also don’t like painted brick. But white wash paint worked beautifully. I’m so happy with the results. I can still see enough brick detail, but the fireplace is no longer a sore point. If you’re talking about a brick fireplace.
If its real sooty, I would use Paint & Peel, https://www.youtube.com/watch?v=1jFlqynHYcU&t=23s
