Lead staining

[AGlassAct]

As per picture really, tried everything I have and can't shift these annoying silver/shining stains - from a distance they look like cobwebs!!! Would 'rub off' be too harsh on these? They are UPVC with foil finish. I have tried: Magic sponge, upvc restorer, Virosol, upvc solvent cleaner, isopropyl alcohol, MEK (for literally a second as the fumes nearly knocked me off the ladder!!). The magic sponge had the most affect but started to give a Matt finish. This one seems to have got me for now and I do not want to be defeated!!!

I think rub out should be fine mate.

You've thrown everyrhing else at it so why not?

Cheers Green - it's the only thing I don't have so will get some ordered.

Oxalic acid will remove it

Cheers Daveyboy. I was a bit worried about putting anything too harsh on it as its foil finish - is Oxalic acid safe on stuff like this? I have hydrochloric and sulphuric acid but my balls went hiding at the thought of putting it on this finish!

Oxalic acid was recommended to me by the guys on the softwash facebook forum for any staining from rust or lead when using hypo and being left with these horrible stains

Also good on upvc if your hypo turns the plastic yellow due to the mix being too strong..it always goes back white within 48 hours but some customers would want the marks gone before you leave

IMHO @AGlassAct the window, frame and the sill are clean. That's the job. It isn't to do a frame restore.

If you tried one of the products and they worked, what then? Would you be tempted to give each window frame corner on your round a little rub with some of the magic potion on a cloth? I know I would, hence the reason why I tend not to bother going that far.

We have a couple of customers that clean white UPVC frames we clean themselves with T cut and then polishing them up with Simoniz car polishing wax. They look lovely once they are done, but I'm certainly not going to offer that service.

I agree with the first statement spruce, I've not had any complaints and they are clean - it's mainly curiosity from my perspective to see if others have had similar. If I am asked to remove them I will, I like to think I can get most windows close to 100% as possible. A few of my customers also like to polish ther sills (steady on!) - saves me a job, but these are the retired guys that have nothing better to do. I don't mind doing it, but obviously charge for the privilege.

Cheers all - unger rub out ordered and I will put Oxalic acid on the list for next time.
