Method options are drawer, modal, and flip. I would have liked, and took the most scrubbing on my part. While the bricks are still wet from the second application, take a scrub brush and work from the bottom up (to avoid streaking) in small circular motions.

If your fireplace is older than 20 years, you may want to opt for a less abrasive cleaner and steer clear of the vinegar solution.

Thou shalt not clean until the mortar has cured.
Cleaning before the mortar has cured – usually within seven days – may damage the joints. Results may be unpredictable if you use the cleaner for anything else. Test each kind of surface and each kind of stain. Test under the same conditions you’ll have for cleaning. This is perhaps the most critical step in giving a building a uniform, clean appearance. The cleaner can’t soak into a thoroughly prewetted surface. As you move down a wall, cleaning as you go, make sure to prewet as you go.
Thou shalt apply the cleaner with low-pressure spray or masonry washing brush.
High-pressure spray – above 50 psi – drives the cleaner right into the brick. Stains and residue can also result from letting the cleaner “dry in” to the masonry. You can also reapply the product for an additional minute or two if the first application is drying out too quickly.
A few passes with a garden hose is not good enough. On outside surfaces, high-pressure water-rinses of at least 400 psi and four to six gallons per minute are standard. Then wipe it off with clean water and a sponge or soft-fibered brush.
Thou shalt not clean in cold weather without special precautions.
Extend dwell time by 10 -20 percent, but don’t let the cleaner dry in.
Consider scaffolding covered with polyethylene. Never try to guess your way through problems or questions. Some justification includes that it’s less expensive to hire out, expand the time frame and get it all done at the end of construction.

Contractors must allow timely cleaning tasks to be performed in the building process to reduce risks of employing cleaning methods which are too harsh for the material and damage the exterior of a building before the client even gets the keys to the front door.
