Final answer:
To mop open areas using a push-pull stroke, start in the farthest corner and work backwards towards the entrance, using a 'figure eight' motion for efficiency. The mop should be regularly rinsed and the water changed when dirty.
Step-by-step explanation:
To mop open areas effectively using a push-pull stroke, begin by dipping the mop into a cleaning solution and then wring it out to avoid over-saturating the floor. Start at the farthest corner of the room and push the mop away from you in a straight line. Once you reach the end of the stroke, lift the mop, return to the starting position, and slightly overlap the first stroke with a new one. Continue this push-pull method, working your way backwards towards the entrance to ensure you don't walk on the cleaned floor.
Remember to routinely rinse the mop in the cleaning solution to prevent spreading dirt and to change the water when it becomes dirty. In addition, use a 'figure eight' motion for more efficient cleaning, as it helps maintain a consistent path and minimizes missed spots.
