i've been using dunlop's formula 65 for almost 3 years now. Does a good job wiping off thick grime or oil from glossy surfaces to restore it's shine, my only bad is that it doesn't stay that way or leaves a 'protective' layer on.
I've tried that on other surfaces too, like my spectacle's lenses, mouse pad, table etc. Cleans wonderfully. Doesn't spoil my wood.
