On the damage caused to rock by brushing.

North East climber and photographer Mark Savage recently sent me a photo of the damage done to the classic Bowden problem Vienna. The damage is obviously due to its popularity and Vienna is certainly not unique in this respect. There will be classic problems all over the country which are sadly changing for the worst.

One of the causes of this damage is from excessive brushing to remove excess chalk so as to improve the grip between fingers and rock. We all do it and it’s almost become a ritual, part of the mental process of preparing for a hard send. However it’s worth questioning how effective this process is, is it worth the damage it causes and are there better alternatives for improving the friction and therefore your chances of success?

I have done plenty of brushing in my time and my company even sells brushes but in most cases I don’t actually believe it does help to improve the friction. The only cases where it might help are where the hold obviously hasn’t been brushed for a long time and is really caked in chalk. In my experience this is not often the case and holds generally are pretty clean. If the hold is relatively clean and by clean I don’t mean free of chalk I just mean free of large particles of chalk or layers of chalk then brushing is unlikely to provide any advantage other than a psychological one. I certainly don’t see how it will dry out the hold and remove moisture which is really what you want. Therefore in most cases I would say brushing is pretty much a waste of time and the benefit will be far outweighed by the long term damage you will do to the rock.

Even if you are dealing with hard rock types which aren’t easily damaged, at the very least the hold will become polished over time. You can see polished holds everywhere and although I am not saying that brushing is the cause of this polish it’s certainly a contributing factor and should be avoided where possible. Where it is necessary to brush a hold it should be done sensitively, gently, in moderation and with a soft natural bristle brush.

Years ago there was a huge controversy over a front cover photo of me climbing Brad Pit at Stanage with a “pof” on the ground below me. For those of you who don’t know, a “pof” is a French invention from the forests of Fontainebleau. It’s basically a rag filled at one end with pine resin. Once constructed you end up with a round ball of pine resin at one end and a long loose tail of material at the other. The French used to “pof” the resign onto their hands, rubber and the holds, then use the tail end to whack away the excess and aerate the hold. Some would then use chalk on their hands, others would do without the chalk. I tried all combinations and really didn’t like it so stuck to chalk. The British didn’t like the resin and the French didn’t like the chalk and on more than one occasion whilst using chalk in the forest of Fontainebleau I was subjected to a wagging French finger and the words Non, non, non! Over time I think the French realized that actually chalk was better than resin and it’s now very rare to see anyone using a “pof”.

Anyway when British climbers saw me climbing on the Peak grit with a “pof” they were rightly up in arms. Having seen the damage that resin had done in Fontainebleau I couldn’t agree more however although there was resin in my “pof” I wasn’t using the resin part of the pof just the tail end to whack the holds. This has a similar effect as brushing but is in my opinion much more effective and does far less damage. The force of air generated by the tail end of the pof has the same effect as wind drying out and cooling the holds and thus improving the friction. Neither of these effects is achieved through brushing.

I am certainly not advocating the use of a resin pof but there might be many benefits in replacing the resin with chalk and the brush with the new chalk pof.

I made a similar point using sparks at Rivelin as an example and it was suggested at the time I'd got it wrong, it wasn't over brushing just sloppy footwork that was causing the damage. I think stopping using toothbrushes and nylon wash brushes would be a great start to stopping the damage.

That handhold on Vienna, due to being incut at the back has almost always suffered from rather over zealous brushing. I'm complicit in the damage, since it took me circa 20 shots and I was most likely using one of those black Metolius brushes that everyone was sporting and if not it would have been a reach toothbrush.

These days I use soft brushes and a whack (which I have been using for about ten years, I think it's probably visible in most of not all my YouTube type clips ).

Using the 'tail' of your pof rag, which is used to whack away excess pof, to aerate holds will inevitably end in some pof going on the rock. 

Using a rag that doesn't incorporate a ball of pof, hasn't been in contact with or been used to remove excess pof will not bring pof into contact with rock.

Just saying  :-\

Yeah, Ben came into criticism at the time for exactly that. It's clear enough that Ben didn't need pof to succeed on brad pit, when that photo was around the same time as him doing karma.

how much brushing is still effective depends on the grain of the rock and on the brush.

on very fine texture even a thin layer of chalk is noticeable, and viceversa.


i agree that whipping the hold with a piece of cloth does a great job. In fontainebleau it is noticeably better if the rock is on the sandy/softer side and the hold is large, while brushing is better on smaller holds and harder rock (the extreme case being grattons)

I reckon a bigger issue (though the two go hand in hand) is climbing on damp rock. At least it is in the Peak (on fragile grit and magnesium limestone) and in Northumberland. I've noticed a few problems recently logged on UKC the same day I've been to look at something and it's been wet. With chalk/toweling, it's possible to dry the rock enough to climb it, but that doesn't mean it's 'dry'. There's a reason why Bowden has so many broken problems, the Pebble at the Plantation is a complete mess and why holds snap on magnesium limestone so frequently.
