How to get stains off white UPVC sills?

archieboy

Can anyone tell me what to use on my outside window sills? They seem to have been marked with insect droppings. I've used Jif cream on an old dishwashing sponge/scourer. Then I bought UPCV cleaner. I've got the original 'droppings' off but it's left a brownish stain on the white sills. Is there anything that will remove them?

I too would like an answer to this as house martins have pooped continually over one sill in my new house and although removed, a brown deep stain seems to be left. Any answers please?

an internet search will bring up a multitude of upvc cleaners - I got mine from a local window company (you're bound to have one not too far away?). I have also seen it in several pvc product stockists (guttering, fascias, soffits etc).

I've just had a new roof on my conservatory and they cleaned all my frames with a general purpose solvent cleaner (he said from most hardware stores) and they've come up like new.

I used to use that Astonish oven cleaner paste bit messy though...

I use any whitening toothpaste as for me it gets all those bird markings off my upvc window sills. After i have rinsed the window sill i then use Mer Car polish but any liquid car polish will do. I do that twice a year as i only then need to use a damp cloth to get all the muck off.

bleach will get the marks off - but eventually turn Upvc yellow.

I use one of those magic sponges from the poundshop or Aldis. I ALWAYS have some as they are the only thing that gets crayon or felt tip pen off paintwork (even emulsion).
