Best way to clean lichen off of a new route

I'm thinking of putting up a first ascent on a very lichen covered piece of Slab and have no idea on the best way to go about cleaning it. I assume it involves rappelling and an immense amount of brushing. I was wondering if anyone happened to have a preferred method, or possibly some tips that may make this ordeal more timely. Any suggestions are greatly appreciated!

Some folks prefer leaf blowers, power washers, etc...kinda depends on what you have available.

Thanks! That's a great article!

I think just leave it and climb. let nature decide who stays: climber or plants.

If the route is too overgrown, it might not be worth while. A lot of time, the lichen / moss will return as water washes down the rock. If you're simply looking to clean off some hand and foot holds and its not too overgrown, a wire brush will do.

Climb it, a lot!
