Karen from Palmerston North has this recipe for a homemade alternative to commercial sugar soap for wall cleaning. You need: 1/4 cup of white vinegar, 1/2 cup of laundry detergent (unscented is better), 1/2 cup sugar, and 1.9 litres hot water. Mix ingredients well then apply to walls with a sponge, terry cloth (which is a towelling fabric with loops that can absorb large amounts of water), or a microfiber cloth. Rub gently until clean and wipe dry (you can rinse if you wish, but most of the time it is not necessary). Be certain to clean from the floor upwards, in sections, and wipe off any dribbles. This is not the same formula as commercial sugar soap, but works just as well.
