Try 'Googling' salt, vinegar and bicarbonate of soda. They have literally hundreds of additional uses, from teeth cleaning and deodorising fridges, to weed killing.

Here, in UK, we had a series of excellent 10 minute tv programmes called "Tips of the trade" in one of which, the housekeeper of a stately home showed that she used diluted vinegar to polish antique furniture. It certainly works on mine - which is just old! It also does a first class job of window cleaning, polished with newspaper.
