I used white viniger to clean mine...BUT, mine were the 28-29 styles zinc strips and cound put all 8 peices in a PVC tube and let them soke for a few days then clean with water and shine with 3-M cloth.
The 30-31 trim material, if original, is also zinc...just how you could take them apart to clean I do not know that 1/2 of the question.
