improper crank arm cleaning.
is it improper to use an accurate sized die to clean the crank arm hole where your pedals thread into???
ive found it to be the only way to get a ton of dirt out, but dont want to get too comfortable if its damaging

Keep in mind....
Right-Right, Left-Left.
You'll probably need a special pair of pedal taps, right and left.
I would probably clean the threads with pushing a rag through and twisted as needed.
If you use the pedal taps, I'd try using them simply tightening by hand without the holding tool.
I'm not seeing any pedal "Chasing taps" for sale, at least what I can find. However, an option might be to make your own out of an old pair of pedals.

Compressed air & an extra firm tooth brush.

on the synapse we use, the rear of the left crank threaded pedal insert is where i tend to thread the die inversely
i never use the holding tool to make sure i "feel" it thread properly.
though i have never thought of using old pedals before

Tooth brush. If that isn't good enough, get a tiny brass, stiff nylon, or steel brush that is available in any hardware or auto parts store.
Or the cone shaped metal brush that is used to clean battery cables.
But what comes to my mind is that his those threads could get significantly caked with tough to remove grime? Aren't they always filled with pedal spindle threads? I've never seen it.

Changed out a pair of pedals yesterday for a new pair I had bought a while back; they were getting noisy, and had play when I checked them. I put grease in the threads of crank arm, but didn't think to clean out threads first. Sucks getting older; I'd never have made that oversight when younger. Felt some grit when threading in New pedals, but no problem turning them in. After reading this thread, I'll never make that mistake again!
