Cleaning UPVC window frames.

I have just got around re-decorating a room that I gave a quick coat of Magnolia to make it habitable when we moved in here 7.5 years ago! It had been very badly decorated in the past (more than once going by the vibrant colours) by a somewhat slap happy painter!
My problem is that they have got pink and purple paint on the white UPVC window frames. Can anyone suggest a method of removal?

soak overnight with wet cloths, then emulsion should wipe off.

It took overnight. It just wiped off like a film.

hot cloths like you get at the chinese take paint off hands really easily.

Hmmmm, not sure how could keep wet cloths clinging to vertical window frames overnight.

We had emulsion on some of our rads. I found that B&Q own brand paint and varnish remover gets this off a treat. *But* I don't know whether the stuff in it (benzyl alcohol) attacks UPVC or not, so if you do use that (at your own risk) you'd need to to it on a small spot first.

Angle grinder? Or perhaps a plastic foam pan scrub with white spirit on the rough side of it. Be gentle and it will work fine.

If you have ` a feel` for it you could use metal soap pads but dont attempt if you have never tried before without experimenting first. I can take the grime off old french polished wood and you can feel as it just breaks through the grime and goes smooth, its a delicate touch but you get used to it. I would start easiest and safest first (water) then move up a rung if that fails, very mild abrasives / scraping. I generally start these type of jobs that way and escalate to the point of `if I cant fix it I will need to replace it` when I have reached that point anything goes and usually then works.

If you want your windows to look like cr-p forever, you could do that. I sure wouldnt.

That works well, but keep an eye out for any nicks in the blade and change it, as they will very easily scratch the uPVC.
