Just had the lounge re-decorated so need to bring the window frames up to stratch - what's best to use?

u can get a solvent type cleaner ,but sorry not sure what it is called.it works though .

Car polish.

Use T-cut or Brasso to remove fine scratches, then polish up with a cleaner/polish like Mer, or Autoglym resin polish.

Sugar Soap brings them up a treat!

or Jif type cream cleaners

You can also use Super Glue 'Activator', which is what I use on Upvc trims etc.

If you go to your local Cladding supplier (Don't use Wickes, they will be twice the cost) they have specific Upvc Cleaner

UPVC cleaner Wicked stuff...

Don't use anything abrasive Rob it will scratch the surface of the frames.

Soft cloth, warm water, washing up liquid and elbow grease
