No, you must always use 2 buckets: one bucket with the water/shampoo solution, while the second bucket with only clean water. Every time you finish passing the glove over a car panel, first rinse it in the bucket with clean water and then immerse it in the bucket with the water and shampoo solution. In this way you will prevent any residues still present on the surface from clinging to the washing glove and being moved from one panel to another, creating micro-scratches called swirls.
