Easiest way to clean rust in between the zipper? (Pictures attached)

What is the easiest way to clean rust in between the zipper teeth? All my brass is shiny and like new, except for in-between my zipper teeth?

I do have brasso, and a tooth brush if that would work, I just didn’t know of any easier was to get all that green gunk out of the teeth...

I would also like to know lol! I took a baby wipe and individually jammed it between the teeth with my nail on my pochette accessories which worked ok but took a loooong time and there were still some parts I couldn't get cleaned fully. The toothbrush may work better. A qtip definitely does not work. I tried metal polish on a qtip and while it cleaned the outside teeth, it also resulted in polish getting stuck between the teeth...
