Sweep the floor thoroughly to remove all loose debris from within the pitted areas of the vinyl flooring.
Fill a bucket with hot water and 1 ounce of liquid detergent.
Dip a mop into the mixture and spread the hot soap mixture over the surface of the pitted vinyl flooring.
Squeeze out all excess moisture from the mop and wipe the detergent mixture into the flooring surface, using small circular motions.
Rinse the mop head periodically, squeezing out excess moisture each time.
Continue mopping the floor, adding more hot detergent water as necessary, until the embedded dirt has been lifted and rinsed away.
Allow the pitted vinyl floor to air dry.
