Here is a building built in 1926 in Milwaukee WI and it has never been cleaned before .
We enjoyed restoring the facade of this old red brick building. It was cold and snowing a bit on but we worked on it till the evening hours to restore it back to it’s clean unpolluted color.
What causes the brick to turn black?
Well years and years of pollution like vehicle exhaust and other air born pollution.
We spent days gently washing these bricks and it came out excellent.
