I was recently in Athens and went up to the Acropolis, it was fascinating to see how polished the rock is up there, the flat (horizontal) walkways are like walking on an ice rink in places, (people were slipping over on flat surfaces) which got me wondering about the future of some crags.
As climbing becomes more popular are we going to find some crags, particularly easily accessed/easy/classic areas become unusable due to extreme polish?
which raises an interesting question of how long (if at all?) does it take for rock to recover if not climbed on?
Your own evidence from the Acropolis suggests that recovery isn't going to happen at all.
So, get those classics done while you can!

Presumably the walkways of the acropolis haven't been left 'fallow', as per the OPs question of recovery 'if not climbed on'.
Mind you I can't imagine many people obeying rules to leave classics unclimbed to allow the rock to recover (if that is even possible).
Long Climb (S 4a) suggests a very, very long time.
I remember the closure of the Portway under the Avon Gorge in the late 70's. (They blew up a lot of unknown Buttress). The Gorge is limestone and climbing traffic dropped considerably. My memory was that some of the polished holds significantly improved during that period before general access was resumed. Possibly due to acidic rainfall,

From the title, I assumed you were announcing a modern and relevant addition to the Classic/Hard/Extreme Rock lineage.

Yes, that came to my mind too. Some of the glassy classics on Central Buttress had returned to being pleasantly grippy - for a while. I believe they were closed for about five years?

You get the same issue on limestone bridleways. Continuous stretches of rock can be really polished and can be very tricky for MTB riders when wet.
I've often pondered taking a battery drill powered needle scabbler to some of the worst bits but never built up the courage.
A weak acid would likely do the job a lot better, however I'm not sure this would be a particularly ethical approach!
sea cliff limestone is never polished afaik. water dissolves limestone particularly well in the present of salt. perhaps that indicates a environmentally sensitive way of removing polish.
Portland, Torquay. Not sure what the Ormes are like these days haven't been for a while. Even some areas of Pembroke are showing signs so I think you are wrong.
The soft limestone sea cliffs of Malta (& Gozo) are as sharp as a bastard, and seem to get re-sharpened every winter!
Must be the limestone type.
Shelled sea creatures would be quite upset if seawater dissolved them!
I don't think limestone gets unusable due to polish, it's just harder to use.
Does this not lead to a situation where all the easily accessible/easier limestone routes become unusable for most people though?
I don't see why. Harborough Rocks is pretty much uniformly glassy, but it's still perfectly climbable, even for beginners.
> A weak acid would likely do the job a lot better, however I'm not sure this would be a particularly ethical approach!
In man made quarries is it still considered unethical? These areas would surely be ideal for the us as they get used regularly and are usually sport routes. I wonder if the ethical view will change in time 🤔
Careful now, someone is reading this and taking you seriously. The one thing I've learned about rock is it doesn't grow back. Attempts to improve things are nearly always bodged.
I guess it would be the chemical equivalent of chipping which most people would agree is totally unacceptable.

A few, I guess, but most times polish only makes half a grade or so difference at most in lower grades (where I am), as holds tend to be positive and aren't so dependent on friction.
Maybe all the polished routes will help incubate the next generation of top level climbers....forcing them to get their footwork right early!
When Pembroke was first being developed the rock was like razors. A long weekend would leave you with bleeding fingertips, furry rope and rock shoes looking like they had been put on a belt sander. Three years later, after climbing at St Govans, all the gnarly bits had gone.

Plus all the worn out gear placements! It would be interesting to get a view into the future and see what that holds for popular crags. Will Harrison’s be a beach in 100 years after all the traffic or will access be tightly regulated? I suspect the future will be plastic and wouldn’t be totally amazed if popular crags get a protective coating!
portland is a way Above the sea. Can't see a lot of waves crashing over Blacknor
Saw thread title. Thought "That's an odd pick for the enxt in the Classic-Hard-Extreme series"
I don't think route has seen much traffic since the railway closed in 1970? My understanding of Laddow is that it is a heady mix of vegetation and polish. Tasty.
As a Chudleigh fan, polish isn't really a problem, but just another experience. If you push your foot into the hold, rather and along it, it can't slip, however polished. (Easier said, than done.)

I came across epoxy resined covered holds on a crag above lake como about 25 years ago. Interestingly , the locals had chosen a relatively fine compound so the friction was probably comparable to the original smooth limestone.
I pulled a foot thickness of turf off a hold on a Laddow route and the rock was polished underneath!
If the holds are big enough to maintain a foot of turf - that sounds like my kind of climb!
Twas a mod.

Limestone can.
OP: there seems to be a strong majority opposed to using acid to restore a rougher surface to polished limestone (I don't really agree, but if that's the consensus, so be it). So I instead suggest setting up ongoing water seepage from above, to hopefully build up some fresh new tufa.
I'm not sure what etching with acid is going to achieve - it will simply repolish in a few weeks
