Clean the windows after the construction period

Hello everyone!

My wife needs advice...

We want to clean our windows after installation!

There are of course the typical construction site residues on them...

From the outside, grinder dust from the neighbors' roof tiles, etc.
From the inside, residues from grinding and chiseling work by the plumber and electrician. Splashes from the interior plaster and screed, etc.

Now that the dirtiest work is done, we want to check the windows and frames for scratches, etc. and give them a proper deep clean.

How should we best proceed without causing scratches?

As always, just lots and lots of water

Our general contractor commissioned a window cleaner following the expert's advice.
Dish soap, water, cooktop scraper, and a solvent for screed residues

You don't do anything there. Or do you want to influence something?

We did it ourselves, using the same materials as haydee writes plus [Aufkeber-Entferner] from the hardware store, because there were a lot of adhesive residues. It's a very annoying job, but afterwards you know your windows.
