My Dad always uses semi chrome and to wash it i think he uses (please help me if i am wrong) SJ100. Also If your chrome is'nt that dirty I use a wading polish by Eagle 1 it looks like fiberglass insulation in a can and you just rip a piece off it and it already has the polish in it works great.
there's hope in the words and emotion in the eyes
it's so easy to be misled by the savvy gentle guise
and like fools we trust the delivery
but it's all just drunk sincerity
