It will depend on the "stuff" but you need to consider several factors. If you can determine "stuff", that will help. Is your door wood or metal? If wood, stain vs. paint will make a difference.

Magic Eraser or blue Dawn in warm water might get it but if that doesn't, you can make a hard water solutions of vinegar, blue dawn, & lemon juice. Fill a spray bottle 1/2 full of vinegar then 1/4 dawn and 1/4 lemon juice. Let sit 10 minutes to loosen. Then using a warm bucket of water you can scrub using a Scrub Daddy sponge.

It would also depend on whether your door is wood or metal? It could be just dust on a dark door. Or it could be a type of mold on a wood door.
I would try a Mr. Clean Magic Eraser
