I did two new lines tonight in the Pass, and they were pretty dirty before I started. Yet, repeated use of the holds and brushing with a simple nylon brush, combined with a bit of 'cotton rag rubbing' (patented low impact technique) did the trick.
Thanks Andy for your blessing - I feel a whole lot better, now I know I've got your approval.
Don't worry about the new problems, I won't tell a soul, least of all you - just in case you feel tempted to spread the evil tyranny of your wire brushing frenzied attacks upon the rocks onto someone else's territory.
I would just get an angle grinder, if I was you. Surely that would speed things up for a time pressed man such as yourself?
