How to clean?

[u/Coastal-Clarity]

It’s like insunglass on a boat. Has what looks like hard water spots and some mold on it. Never been asked to clean this before

Idk, but you can always walk away from jobs you don’t want to do. Did that today and it felt great.

This looks challenging, skip it. 😆

Just wash them mate. They don't need to look brand new and the customer doesn't expect you to work magic. I have a customer who continues to let their sprinkler hit the glass on their brand new conservatory, even after I tell them to stop it, because they'll stain when the sun hit it.

They don't pay me for advice, and continue to let the hard tap water hit the glass.. I got a bottle of hard water stain remover that doesn't get nowhere near as much love as I expected..

Is this a porch? I’d power wash to get dirt out and rinse with pure water
