I have a PCB with no solder mask with a very dense layout and a very fine trace spacing.
I didn't get a solder mask because it's still in the prototyping phase, and it's way cheaper.
I keep having to stop, find the new shorts that keep popping up, and remove metal fibers that are barely visible.
From what I can tell the fibers are aluminum from the pcb so a magnet is no help.
Is there a trick to remove them faster or a way to stop this from happening?

The trick to stop this from happening is to order your PCB with solder mask. Do consider the cost of your time when deciding that it is cheaper to order boards without.

You might also want to consider using leaded solder, as lead inhibits the formation of whiskers, if that is your problem. As long as you dispose of it properly, there's nothing wrong with using lead in your prototypes, just try to keep it out of any final products.
