Do you guys know about artillery fungus and what to do about it? Our pressure washer guy came by and said that their house cleaning process will not take out the artillery fungus. These are very little black dots on our siding and railings on the screened porch. Apparently, all efforts to remove it from the house are not feasible. It also appears on people's cars and is next to impossible to remove it. It is actually more common than thought. Is there anything else to do to get rid of it, other than scraping every little dot with a pocket knife and other time-consuming things?

In the last year, places in the Northeast has real problems with it.

Here's what it looks like:

Try Mr. Clean Magic Eraser. Worth a shot. I've seen it take some stuff off that I didn't think was possible.

Also this:

Bleach, Simple Green, toothpaste and alcohol-based mouthwash have been known to work with various rates of success, and can be tried first before attacking the spores with a scraper. For removing spores off of cars oil, vinegar, car wax and tree sap remover have all worked for people that tested them

Which appears to have come from the same site you found that picture on. Did you try those yet?

Yeah. None of that stuff works. I did a lot of research on this a while ago. I trust the professional house wash forums. There just is no good answer. Magic Eraser works a little bit, but none of the pros want to touch the stuff because the labor is still astronomical.

I know I hate going up against that stuff when I have to paint a house. I've tried everything. Heck, even trying to scrape it off makes it turn into smudges.
