Cif and wire wool...really does work wonders. This was really stained, like rust on it.

Looks good,
I've been using astonish upvc cleaner -  which I'm sure is the same as cif and any other cream cleaners.
I normally use a scouring pad - I'll try some wire wool next time

I don't have the patience for that kind of work.

I suppose it all comes down to how well it pays.....
