Disposable wet mops have become popular for their convenience and ease around the house. But the throwaway pads can be wasteful and expensive too. Save the mop, but skip buying new pads by saving old T-shirts and using them instead. Simply cut a T-shirt in half and wrap it around the head of the mop. Spray a natural cleaner on the floor and mop away. T-shirts are machine washable and can be used over and over to keep your floors sparkling clean.
