I found something great recently, but am not sure that you have these in the States.
A pack of ECloths. The microfibre one used dry is fantastic for dusting. Damp it will clean anything and not need any product to help. The thin one then polishes and dries the area you have swiped with the damp one.
Windows and mirrors, sinks, showers, baths, basins and kitchens come up gleaming. It cuts my housework in half.
At the time I thought they were really expensive. But in three weeks I have saved more than they cost by not buying all those products that offer us hope that they will work! and don't.
If anyone wants to know more about them, I will post a link.
