I have cleaned some pretty horrendous surfaces over the last three years, for our supermarket cleaning. Stores that have never been cleaned and then they expect a new pin finish.
We use a lot of cream cleaners but there is one you cannot beat
Doctor Power £5.00 for a tub and it gets most marks off. I think JML do it and you could buy it in Woolies (not anymore though!!!) and some other high street names
