Hello everyone,
We are about to move into our new build and are now faced with the task of cleaning all the windows properly for the first time. Since a lot of dust, dirt, and residues have accumulated during the construction phase, I want to avoid damaging the plastic frames – whether through the wrong cleaning products or excessive scrubbing.
Do you have any tips on the best approach?
Which products are suitable for a thorough initial cleaning without harming the surfaces?
For car care, I use some products from Koch Chemie, for example. Do you think their multipurpose cleaner could be safely used on window frames, or is it better to avoid it?
I would appreciate any experience and recommendations!

Letting the liquid splash, run down, and noticing it too late, etc.... that can really cause damage.

Trust me, if you want to remove concrete or cement, you use something with hydrochloric acid. It is even found in household cleaning products, just in a very low concentration.
I asked so provocatively because you specifically mentioned uPVC windows. uPVC windows should actually withstand this treatment better than aluminum windows.

I am quite shocked.... with the methods recommended here, you should not clean aluminum, wood, or plastic windows!
I will assume you have the most commonly installed plastic windows today (dark anthracite gray foil on the outside, white on the inside).
The foil manufacturer Renolit has (for years...) really good advice on how to carry out the initial cleaning of the windows...
