any serious answers what this could be please?have you guys not noticed this too?

have a good look at your customers white plastic frames when your working today......its got to be a chemical reaction in the plastic to UV rays from the strong sunshine as this has only developed over the last few months.....

My upvc windows are over 20 years old and as white as the day they where installed, faulty or poor quality upvc can go yellow
but it would be highly unlikely that all your customers would end up with faulty or poor quality frames.

Try looking at them without sunglasses. lol.

The only times I've ever noticed discolouration to white window frames and upvc is if there is a nearby neighbour who regularly uses a log burner (over Winter) or has fires in their garden, which leaves a grey stain.
I've not noticed yellowing.
I suppose it might be due to some local environmental pollution, are there any Factories, Chemical Plants nearby?

It could be hot water affecting some of the frames.

Cheers shrek...

I thought so...it's only on certain customers frames but enough for me to notice....

Not seen any yellowing today  up to now.....it must be certain types of plastic frames....

Anyway better get back out there....it's like a fridge sat in my van!

Its your hot water, anything above 50% degrees effects Unplasticised PVC, time for your customers to sue.

We use water a lot hotter than 50 degrees and haven’t got any customers with yellowing windows or any other plastics for that matter and have been flat out with gfs cleans over the last few weeks

Plenty of people get away with things they shouldnt be doing, its there to read in the link, you shouldnt be putting water on UPVC frames thats above 50degrees,

its nothing to do with using  DI water or using  hot water to clean them........its the UV rays and stuff from nearby plants and trees.......
