Pressure Washing vrs. Power Washing

The main difference between having something pressure washed versus having something power washed is power washing uses heated water while pressure washing relies on the force of the jet stream to pressure clean. Something that is heavily soiled or full of grime would benefit more from a power wash but a professional power washer can tell you if it is safe to power wash that specific material. Not all materials will stand up to the heat of power washing. This is when you would use pressure washing machines.
