Sunglow12- Look on the new 'clean it,fix it' show(BBC1& iplayer) theres a few hints & tips to restore precious wooden furniture items.Theirs came up a beautiful treat! Can't remember the right episodes but watch them all, theyre only half hour shows.& very helpful.I am going to try them on my coffee table/tv stand, as my youngest son (about 15 then) got a mark on it a week after i bought it,that's never come off.He put one of those drink mugs on that you 'pre-cool' in the freezer, leaving a white mark🙄🤨
