I used to by the swifer wipdes for my swifer, but I found it cheaper to use old wash clothes. They are stronger and can easily be thrown in the washer. Not to mention rung out a few cleanings before they need a washing. I save money on gas using Amsoil Synthetic Oil, we change our oil once a year, the car keeps getting better and better as the years pass. we also use the PI and Power Foam to clean our cars insides, this keeps the wear down and saves money on gas and maintenance.
