Eh......my reply is going to be different from others, somewhat.
Buffer trails or wheel marks (also called holograms) are not caused by dirty pads as much as they are micro-scratches caused by the rotary operator not properly finishing out their work.
So let's say we are doing a paint correction and we start with a mild compound, say Menzerna SIP and an orange pad. We level down the marring and scratches but what's left behind are now micro-scratches which take on the appearance of a flowing ribbon within the paint. If we stop here, the paint may look shiny but buffer trails are present. The paint is, what I call, "open". So to lessen the swirls we need to step down the pad to say a medium polish pad and again SIP. We have now further lessened the swirls but most likely they are still there, just finer now.
So now we move to a finer pad and also a finer polish. This step begins to "close" the paint. Think of it in terms of prepping and finishing out a furniture piece made of wood. You'll start with a coarse grit then work your way down to a fine grit which smooths over the wood. So the finer the pad and polish the fewer the swirls.
You can scratch or mar the paint by hand but you can't put in buffer marks by hand. This is because your hand alone cannot generate the needed heat and friction to cause swirls.
You buff edges by either lowering the RPM's on the rotary or by feathering the trigger as you buff up to the edge.
Hope this helps,
