ᐅ Cleaning the windows after construction completion

Hello everyone!

My wife needs some advice...

We want to clean our windows after installation!

Of course, there are the typical construction site residues on them...

From the outside, there is dust from grinding roof tiles from the neighbors, and so on. From the inside, there are residues from grinding and chiseling work by the plumbers and electricians, splashes of interior plaster and screed, etc.

Since the main dirty work is now done, we want to check the windows and frames for scratches and give them a thorough initial cleaning.

What is the best way to do this without causing any scratches?

As always, just lots and lots of water

Our general contractor hired a window cleaner following the expert’s recommendation.
Dish soap, water, a cooktop scraper, and a solvent for screed residues were used.

You do absolutely nothing. Or do you want to influence something?

We did it ourselves, using the same materials as haydee mentioned plus a sticker remover from the hardware store, because there were a lot of tape residues. It’s a very tedious task, but afterwards you really get to know your windows.
