clear side marker trouble

i just found 4 clear markers, left and right front and side for my cherokee, but one front one has a whitish oxidaion on the metal reflecting due to oxidation, how do i get rid of this? the light looks discolored because of it...

i solved my own problem, took me a while, but i dremmeled the clear lens of the bad one, and dremeled the orange off the good one, and did a lil' transplant with some goopy goop to seal it up
