You can remove latex paint with denatured alcohol the fastest or with rubbing alcohol or with water, though water will take a bit longer. If the cabinets are finished with a shellac, alcohol will remove that finish so do some testing first. If the cabinets are finished with a poly or lacquer, the alcohol will not affect the finish. For areas that are butted up against the wall, I will soak a small thin rag in alcohol and then wrap the rag around a putty knife and carefully use that to wipe the paint away. You will notice that if you saturated the paint first, it will be easier to remove than if you just try to scrub it off.

As for hinges & switchplate-covers, screws, pins...

If you can, take them off & "boil them!". Just leave-'em in hot water for a few hours. Paint should then basically "fall off", or be easily pulled off.
