If there is an area that needs special attention, we use the appropriate solutions to fix the problem and rinse the area extra thoroughly. As we move out of each room, we replace the furniture that we moved, covering under each leg with either a plastic square or styrofoam elevating block. We then come in with the terri towel system to dry cleaning each room to make sure everything is dryer, fluffier, and extra clean. Many cleaners do not rinse, thus the term "residue" comes from. Rest assured, our solutions will not leave any type of residue.
