Best way to clean cogs?
I have searched for past threads, but can't seem to find what I am looking for. I am meticulous in cleaning my bike after every ride. The one task that is a pain in the butt is cleaning the cogs. I have the usual cog plastic, curved cleaning devices, etc. Heretofore, I had been spraying chain cleaner on the cogs, and hosing them down, but I just read (I believe in Zinn's maintenance book), that the solvent can easily find its way to wheel bearing grease which of course it destroys.
Does anyone have some great method (without cog removal) for making the cogs and spaces in between look as shiny clean as my chain?

Picked up a dental tool cheap at a flea market. Works great on the caked up stuff. Rag works good from there. Every once in a while, I'll remove the cogs from the body and clean thoroughly

Seriously!
The main problem with dirt on the cogs is that it gets into the chain. Dirt in the chain wears out the rollers. Worn chain rollers lead to chain stretch, which causes stress on the cog teeth, which causes worn out cogs. The dirt itself won't directly damage the cogs, it's a worn chain that will damage the cogs because that's where you have the metal-on-metal contact. There's no reason to go all that crazy cleaning your cogs every day. If you want to go crazy cleaning something, make it the chain.

I also dry lube it at least every other ride. I just would love for those cogs - especially in between to be shinola shine a glaze!

I use a terry rag stretched across the edge of a tie plate, a flat metal square about the size of a credit card that sells for a few cents at any home improvement store. I spray the cassette with degreaser and then push the plate with the cloth into the gap between the cogs. I hold the plate stationary and turn the cassette on the freewheel with the other hand...this is with the bike on a repair stand. It cleans it down to the spindle and makes the job go quickly.

I think the best tool i ever got for cleaning was the pedros cog cleaner brush. I payed 3.99, it has large nylon bristles probably 1.5inch long at the longest part. That thing works on everything

I used to fret over my chain and cassette. I would spray so much degreaser around that i often flushed out my hub grease. Now I NEVER spray degreaser on the cassette and usually only clean it if it is really gummed up. At that time i try and just put the degreaser on the rag.
I ride every day year round and after 5 or 6 thousand miles i learned that dirt on a mountain bike is just fine. Same with lube. I used to over do the lube on the chain. All it did was attract more dirt and draw more grime. I still lube but i just don't worry about it. Sometimes i lube, sometimes i don't. Only if my chain is really chattering do i worry.

I've heard a thin pedal wrench with a thin cloth around it works well. The right size cotton rope works well too.

It only takes, what, 10 minutes to take the cassette off, and properly clean the cogs. I use Finish Line spray citrus cleaner, and those gears back there are always clean. So, why even mess around with trying to clean them while they're mounted. And if you're really a clean freak, this is the only way you should be satisfied.
