Window cleaner not drying windows

[Orangedaisy]

Genuine question as I’ve never had a window cleaner before-I’ve always lived in a flat or bungalow so I did my windows myself. Should they dry/polish the windows? My guy just went round with a big mop on a pole and scrubbed them all but has gone leaving them all covered in droplets of water, which will no doubt leave water marks? He’s been before and I’ve never been impressed with the finish but I’ve never actually seen him do the work.... What does yours do?

Mine uses a cloth/sponge and bucket and then uses a squeegee thing after. Wouldn't be happy with loads of droplets.

They will probably be using that ionised water or whatever it's called. It doesn't leave marks so they don't have to wipe it off.

Mine leaves them wet and they dry without marks.

Mine does the same as yours. But we don’t get marks.

Time will tell then, thanks for the replies. Popping out now then will inspect again.
