ferric chloride; buy it from a chemist, it mixes with water and is highly caustic---seen a fella use it on a vw pd engines inlet manifold (on another forum) and it eats what it touches !!!!!
once brake fluid has got onto the shoes, it soaks in---so even when you rough them up and spray them with brake cleaner/carb cleaner/petrol and then set fire to them !!
all you are really doing is cleaning the surface;
given, they wil look all nice and clean again and when refitted (as when you apply the brakes) , the heat from the friction will draw the fluid towards the surface and cause brakes to pull /snatch on that side.
if dry friction linings get soaked in oil/brake fluid then they are effectively---finished.
