Anyone know of a good cleaner to fetch off yellow cigarette tar? Ive got a big conservatory to clean inside that is pretty much there kitchen, so they have cooked and smoked in it for years, its very yellow and im not looking forward to it at all but sorted a decent price! Also its very high i shouldnt have any trouble with the panels its just around the top beams/fan etc is there anything i can waft around up there, if i cant get to it with my hands? Thanx guys hope you can help me.
