Cleaning soot off of brick?

Has anyone had good luck cleaning soot off of exterior brick after a fire? What chemical do I need to use?

Try brushing F13 on it

I did one the other day and IMHO it’s better to do the ole tradition blast it off methods…

What we do is we spray it with anyone of the graffiti removal chemicals we have in our trailer. Let is soak in for about 15 or so minutes then hit it with hot water. This works for us and I suggest to use a face shield if you do this because the chemicals can burn your face a little and you need to protect your eyes most of all.
