Cleaning brass nuts in sandstone

Did a sandstone C2/C3 wall this last weekend, with many micronut placements in pin scars on one of the pitches.  As a follower, I wasn't able to clean a few of the bounce-tested brass nuts, hammering on a normal BD nut tool with other gear on my rack didn't work (we didn't bring a hammer), just seemed like I was messing up the cables more than anything so I left them fixed.   Any tricks or advice? (other than offering beer and karma for their return)

I don't mind that we left the gear, other than that it takes the challenge and fun away from the next group; and maybe we'd have wanted it on higher pitches. I've done many trad climbs over the years, and a few other sandstone walls, including Desert Shield, and never had an issue with cleaning gear before, and would like to avoid this in the future.  Thanks.

A thin steel nut tool, or somthing like a straight dental pick

Carry a hex to bang on your nut tool? or carry a flat rock in your chalk bag.

Using the sides of a heavier cam like a BD #3 to hammer on the end of the nut tool can be handy for stuck nuts. I've heard spitting on stuck gear in desert sandstone can make it easier to remove by dissolving the bond between sand grains, but that's kinda gross and probably contributes to the slow widening of often-climbed cracks. Brass nuts are just kind of a PITA to clean sometimes.

I made a "clean aid" hammer for just this purpose. It is a small 6" ball peen hammer. drilled a hole through the handle and now it hangs on a carabiner on the harness of the follower. So much easier to clean bounce tested nuts. Lots of practice with brassies in sandstone on Moonline Buttress and The Titan. Also used on El Cap. Heavier than no hammer, but you don't lose those expensive brass stoppers.

After leaving a few micro nuts (they're expensive!), I did the same as Ryan H.

Where on Moonlight did you need brass nuts?  Moonlight should be all cams and NO bounce testing.

P8, often called the nutting pitch. This was my 2nd aid route ever so it's possible that now I might be able to get more cams in, but at the time it seems like mostly small nuts. I probably wasn't the smallest brass off-sets, but I recall fishing in more than a few small sizes.

+1 to using a small hammer with a nut tool. This comes in handy and makes cleaning nuts very quick and doesn't damage the rock.

try tapping with your ascender?

I had similar experience on P2 of Touchstone, after the roof I placed mostly nuts and my second couldn’t get them out. I’ve never left a nut except as a bail piece (never climbed sandstone before) so I rapped down to get them and had to beat them with a palmed grigri, most of the wires were so kinked I ended up retiring them anyway. I won’t be getting back on clean aid on sandstone without a hammer. That said I have heard a small spray bottle with plain water helps free stuck pieces in sandstone.
