Lemons and vinegar are the great dynamic duo of green cleaning, but there’s nothing quite like the smell of fresh grapefruit. It’s fresh and sweet, and can give your bathroom that extra boost of freshness that is usually only obtained with heavily scented candles and other cleaning products that aren’t so earth-friendly. I recently moved into a home that had sat empty for a year and while it was in great condition, the old cast iron tub looked pretty rough.
