I know that if you use too much detergent and hand clean (eg: Georgian Windows) it's likely to look smeary in full sun. But does anybody know why too much detergent smears?

Also I occasionally get a white bloom on the glass(easy to polish off but irritating!). It's coming from the upvc frames but what actually is it and is it possible to avoid?

Cheers

detergent always leaves a residue behind, especially the ones with "good glide"

fairy is the worst offender.

I use Squeaky's tip.

Get some Tesco's own brand window cleaner, lightly mist the windows (Georgian or leaded) and buff with a dry clean scrim or micro fibre.

Check how dirty the windows are first though; if they're still pretty clean; LIGHTLY, and I mean LIGHTLY mist them with the spray.

The white bloom could be coming off the PVC frames. I have a few like this on south facing windows. A good scrub with WFP sorts it out.
I thought that chalky frames would become a thing of the past with PVC but old PVC can chalk too. Dai

Cheers guys. I'll have a go at Squeakys method.

Dai, is this chalkyness on south facing frames the effect of sunlight fixing on years of window cleaners detergent overspill? That then runs off and causes the problem?
I am asking if that is what you are saying.

The problem could be the seals round the panes are leaking, so all the white bloom is coming out when you put water any where near them.
