What are these stains and how dose one get rid of them, used some Screwfix degreaser at a 10:1 ratio, sprayed, agitated, let soak for a minute or so then scrubbed again with the sill brush, lightened them slightly but didn't get rid of them at all?
I know it's probably on here all the time but I need your expert advice. I'm guessing it's an Unger rub out kinda job?
Thanks
