Remove aluminum siding oxidation stains from brick

Not seeing a lot of action on the forum about this type of cleaning. Definitely a problem in my area. What takes care of it? Graffiti removal products? There is a company with a youtube video in my area with a process that does a good job. Looks like a 2 part chemical process.

I had luck removing similar stains with a local product here in Charlotte NC called aqua prep it is HF based and very dangerous
