In reply to Stevie989:
Having just spent 5 days on Lundy cleaning routes, I offer the following advice
1) Clean from the top downwards. You can do this hanging on a Petzl Stop. That will be much kinder to your rope than swinging around on ascenders which grip the rope with teeth. And the debris cannot fall onto rock that you have just cleaned!
2) Keep the ascenders on standby, out of the way. I rarely went upwards.
3) Use rope protectors, or better still, rebelay the rope to protection below rub points. You will swing about more than you think.
4) Use goggles if you are wire brushing. You eyes will get sore otherwise.
Good luck and thanks. Climbers these days don't realise the effort that went into cleaning many of our crags.
