Garbaruk Chainring - removing anodizing and polishing

 Caustic soda. I just got the kind that looks like coarse salt, mix a cap of it with water, dip the anodized part, when the ano is gone rinse and brush the part thoroughly under running water since the solution corrodes and ruins the aluminum if left in too long.
You can take for example an aluminium spoke nipple to "practice on" just to get a hang of how fast the process is, since this depends on how strong you make the solution.
Then just polish it to get a nice finish.
Depending on how big the part is, being outside or having extremely good ventilation is important, I learned the hard way on the first chain ring haha... And sorry if my english wasn't perfect trying to explain the process!

 @bicyclerider: Your English is better than 90% of the native-English speaking people here on Pinkbike

Thanks a lot for the explanation! It made perfect sense. I will get some caustic soda and some scrap aluminum pieces and try it out.

 @seraph: Thanks man.
What's cool is that if there is an etched logo on the part, it will still be there after the process. Making it look a bit more professional haha.
Good luck!
