Just tried a very unscientific test that proves nothing but -
I rotated the nylon brush between my fingers and a metal brush.
The metal brush was much harder, uncomfortable on my fingers.
I then wiped the nylon brush on a clean white rag, then a used metal brush.
The metal brush left discoloration on the rag.
The nylon virtually none.
Again just an observation not scientific.
