I am the same way. I feel like a nicely blued shaft is like a badge of honor.
Jokingly Buddy, I see that as someone that doesn't chalk properly, or maintain their shafts.
There should be no reason for blue of the shaft. On occasion, I will get a little under the Ferrule.
When I first start to clean a shaft, I use 400 lightly. You don't take any wood off, and what you see is greenish gunk on the paper. Chalk and hand grease.
I prefer using ME as I feel like MVP, that it has an ability to get into the pores without having to take any wood off.
If the shaft is one piece maple, I may use Acetone with the ME, depending on how bad the shaft is, and I have seen a few nasty ones.
Then I switch to ME with Alcohol. Ammonia with ME works just fine too.
Many of these cleaners are just repackaged House Hold Cleaners. No special design or Magic Formula there.
Of course, never Acetone on a Lam Shaft, and you have to be careful of the ferrule and joint collar, as Acetone will eat 95% of the material.
Once clean, several coats of your favorite sanding sealer, and a few coats of wax.
Once you get a shaft back from me, if you wipe it down after use and try to be good about it, it's good for 6 months and beyond.
I appreciate the info re 2000 and 3000 grit paper being like ME. That high a grit of paper will never do a shaft any harm.
Just thought that I would pass this on. Shafts aren't the only thing that I use ME on.
It's just a great product. Bath Room mostly. But at that price, you can use an entire pad for other things and not feel guilty about it.
For shaft cleaning, each pad gets me 8 smaller pieces.
