Streaks on Garage Door

Any idea what could be causing these streaks on a garage door and the best way to remove them?

My tech cleaned this customer’s garage door with a water-fed pole using DI water. The streaks appeared after cleaning and won’t come off with plain water or a microfiber.

I tested the surface with a dry white microfiber and no black/grey residue came off, so I’m not sure if this is oxidation.

Have you dealt with something like this before? What product/cleaning method would you recommend to safely remove it without damaging the finish?

Appreciate any advice

What's up, y'all. I'm new to mid/high-rise commercial and received a window cleaning quote request for 6 hotels by a group that owns all of these hotels. Not sure how to price them, but I counted up the panes and number of stories. Just for clarity, in my definition, a pane of glass is a separate piece of glass separated by a frame or sill. Not a full window unit with multiple panes. For context, I am in Ontario, Canada and their current window cleaner is not available so they reached out to me.

How much would you guys charge?

How long of a WFP would I need? I was hoping to waterfed most of them. The 6 story ones might be difficult and may require a boom to complete but I was wondering if I could get away with a WFP. They don't seem like they want to spend a ton of money so charging for a boom could get pricey.
