What if there are still smears afterwards?

Let us know via the contact page, by email or by telephone. Include a photo, say which window it is, and whether the smear is on the inside or the outside.

We look at the photo and tell you what caused it. Often the smear is on the inside, while only the outside was cleaned. Condensation, dew or rain can also leave drops that look like smears.

After that, we agree with you on what happens next.
