Peg, Palmerston North.

I use white vinegar for all my cleaning, pure in toilet, a dash of detergent/janola/water for very grubby spots.  Great for windows, use in spray bottle.  Ovens, white vinegar,  juice of a lemon, another dash of Janola and detergent. USE GLOVES.  Leave for several hours. And its CHEAP. I take an empty 2lt milk bottle and fill up from the Bulk Bin/Bin Inn.
