I wanted to clean up the switch gear as I'm reusing what I've got. Of the two sets I have one has an on/off switch for the lights & one didn't, of course the set I wanted to use (with the on/off switch) was the crappier of the two!! This bike is nothing if not a challenge!!
To remove the anodising which had faded badly I ended up resorting to some oven cleaner:
After about 45mins the anodised finish was all but gone, just needed to be scotchbrighted to get rid of the oxidised finish. Haven't got a photo so will need to get one of the finished item & upload it later!!
