yes ive got a house that ive tried alsorts ive even tried rubbing seal with  dilute tfr to clean just wont have it i think seals may have perished if you rubb them you get rubber marks on hands or cloth the look

Some types of upvc have a type of gasket (the seal you refer to) that is absolutely soaked in oil when they make the windows.I used to work as both a upvc fabricator and installer and its horrible stuff,i have some jobs that when i scrim edge the glass after trad it leaves a black stain on the scrims every month.

Also the glass has that rainbow affect in certain light noticed it before I started

[AC Window Cleaning]

Sounds like the double glazed unit seal has failed? is there a misting/water between the panes?
I have been called back to a few then pointed out its their glass thats gone.
Then got that job too

[magic moments]

No misting ,just some oil effect that runs evenly along the glass, It may just need a real good scrub rinse,scrub rinse ,but font wanna lose customer so will trad it tommorow and try again next time

just wondering when you clean the windows that have the seals that leave black marks on your scrims what happens wen you clean with the brush does it contamiate that aswell and affect other windows after

[AC Window Cleaning]

Was just going to say i would cloth clean with a degreasing agent 1st or you could clean like that all day.Im not wfp so cant say for sure but if it leaves black marks on scrims..........

a window has 2 seals the one is on the beading that keeps the glass and the other is the glass seal between the 2 sheets of glass.This seal is the one that concerns the water between the glass and is the misty one.The one seal on each beading is stuck onto the beading and this one creates the runs that are black. One can remover these beads and clean them or even cheat to replace them.
