Saturate the EXTERIOR of your brick / brick veneer with clean water and give it a few minutes to soak in.
Put on your respirator, safety glasses & gloves then mix 1 part ACID MAGIC with 4 parts clean water in a 5 gallon bucket. Start with just 1/4 of the bottle.
DO NOT MAKE THE MIX ANY STRONGER AS IT WILL REMOVE ANY COLOR &/or GLAZE FROM YOUR VENEER!
Starting from the top and working your way down, dip your SCRUB BRUSH in the solution and QUICKLY scrub SMALL SECTIONS of your Box.
DO NOT LET THE SOLUTION SET FOR MORE THAN 5 SECONDS! RINSE EACH SECTION IMMEDIATELY!
