The removable spider from my cranks is starting to look tatty, so a refresh is in order.
I'm not exactly sure what is covering the aluminium, but it 'feels' like chrome to me.
In attempting to remove it (i keyed the surface) i have tried - and failed completely with:
1 - paint stripper - didn't touch it.
2 - baking soda - soaking and boiling - didn't touch it.
3 - vinegar - boiling - didn't touch it.
4 - oven cleaner - didn't touch it.
I'm reluctant to apply too much heat as the aluminium feels incredibly delicate/light to me - i'm always surprised at how well it holds up to years of abuse.
I'm reluctant to 'dremel' it for the same reason.
I'm very reluctant to use caustic - the last time i tried that it ate the part in question.
Any ideas what this stuff is please?
And if so, how do i shift it.
Thanks in advance.
