This is a dark art, patience and caution are key, very measured elbow grease is often the main ingredient.
Many techniques can be employed, adding water, soap, using the polish as the soap, cloths and rags, etc, etc.
Knowing when to get aggressive, when to use a solvent to get something nasty off and knowing how to do it without ruining the paint so you can polish the trouble spot.
The learning is endless and if you're careful you can figure out a lot of very serious problems.
