What is this and how do I get rid of it?

Ha! Glad to know I'll be the guinea pig. Seriously thinking about picking up a steam shot and giving this a go. I am somewhat concerned about the badges coming off. The TAHOE lettering seems to be loose as it is. Any recommendations on a compound to use?

I’ve always like Meguiars Ultimate Compound and Ultimate Polish (I’m only a DIYer though, so a professional may have a different suggestion).

And I just saw all your pictures you uploaded this morning. That Bissell Steam Shot comes with a small extension hose and a wider attachment that is useful for cleaning windows. I’m wondering if that would work on all that black mold that you say will come back. However, the steam isn’t as hot once it flows through the extension hose and dissipates through the wider glass attachment.

One negative thing about the Steam Shot is that it take a minute to heat up, and then uses the water up relatively quickly in my opinion. Maybe there is a better Steamer?

In other words, the Bissell Steam Shot is useful in small, concentrated areas in my opinion. Not so much for doing large body panels. I could be wrong though.

It looks like mildew. Use a mild bleach.

This is what I see as well.
