Problem is i don't think you'll find anyone who would disagree with all that, but then pleantly of people will say "but of course its ok for me to use a wirebrush, cos i (think i) do it in a responsible manner, but everyone else should not do it". There needs to be a shift in attitudes in climbing in general that the rules that apply to everyone else also apply to yourself, and even if you think you can flaunt them safeley you can't.
