Even tried a solution of hydrogen peroxide and hot water. The mechanical grinding with some ragged microfibres and melamine sponges seems to shave off tiny amounts as I get the "sparkles" on my glove after awhile, but none of the chems I've tried seem to have any solvent effect on the HCW. I'm beginning to wonder if I've stumbled upon a way to turn HCW into an actual ceramic coating...
If HCW is even a fraction as tough as it is on my handrail, I'm sold.
Any other ideas?
