If you are local to the Triangle area of NC, I'd be glad to give you some.
That's a very kind offer but I am on a different continent!
It's gonna have to be white vinegar and some salt. That's all I can afford at the moment. Then some bicarb of soda to finish off.
Now I need to find out how to take these brakes off. I've never done that before.
