What products are used for post-construction cleaning / cleaning windows and tiles?

Do I need cement residue remover or can I simply clean the tiles with all-purpose cleaner?

We will probably hire a company for the final construction cleaning. Our architect says doing it yourself might reveal construction dirt even after years.

Life is too short for bad tools. Therefore: Lithofin. That stuff is simply magical for tiled floors. You get what you paid for. I awarded this job on myhammer for 700€ or something like that. The two guys were diligent, but they didn’t finish. Still, a big help amid all the moving stress; the roughest work was done (windows, floors, etc.) If you really want it to be good, in my opinion, nothing less than 1500€ will do. You have to decide if you want to spend that.

Regardless of whether we hire someone again before the move, I would like to clean a bit before the inspection. Do you know if I can safely clean the windows with a ceramic hob scraper (for paint residues or stuck-on dirt), all-purpose cleaner, Sidolin, and microfiber cloths? Am I risking scratches? I once read something online about what to watch out for when cleaning windows in a new building, but I can't find it anymore. We have plastic windows from Schüco

We also have plastic from Schüco. I would be very careful there. If there are scratches that are not your fault, it could be difficult if you handle it yourself before acceptance.
