I had a Tuf neck chain ring with hard anodising in black !
Needed it polished up, but oven pride would not shift it - sunstrip stuff - the nasty paint stripper would not touch it
been after a solution on how to shift hard anno stuff for a while
read up a bit and seen a few things written on this subject
so went into the cubboard under the sink and pulled out the drain un-blocker - caustic soda
put the kettle on and poured it into a plastic tub - popped the chain ring in and then poured the crystals in - bugger open the bloody window quick and stick the fan on :D ;D
frothed away and within 30 seconds hooked the chain ring out - bloody hell it worked in seconds
it has taken off the hard anno and left it clean and with a raw finish :4_17_5:
if you do it
do it out side
do it away from pets and kids
don't do it in the house and let the wife see :nuts:
it only took less than 30 seconds - so don't leave it or it will melt !
well i'm happy now I know how to get the bloody stuff off - oh and it was on alloy, so i'm not sure how it would work on tange headsets ?
cheers B ;)

nasty stuff aint it :daumenhoch:

Never used anything different , Caustic is the 'man's' choice :D Strips rims, brakes, seat clamps within seconds ...... especially if you use it with warm water ;) I wouldn't have recommended using boiling water though B >:D :crazy2: ;D
Oven pride is nicely packaged and in a bag for a reason ........ the ladies use it around the kitchen so it doesn't damage there freshly manicured nails ::) Caustic is in a plain white bottle with a skull and crossbones on the front 8)
Defo use it outside , if you inhale a good mouthful of the fumes it literally takes your breath away !!

Well it was Hot water as to opposed to boiling :pilky: i'm not that stupid - well nearly :crazy2: ;D
it was the Hard anodizing that was the bloody pain to shift and every time I asked on here I got no answer ? ???
-
Good bit of info for impatient me.
What do you rinse the stuff off with after?

Tbh im surprised it worked so well on the hard anno , i had a set of hard anno'd pro class rims and they were a right ballache to strip ...... nearly as bad as chrome ! I can't remember if i gave up in the end and there probably still in my garage somewhere :D
Glad to hear the water wasn't boiling B ..... lethal combination , especially indoors aswell :crazy2:

plenty of clean cold water :daumenhoch:

Well don't forget this is on alloy and it might be different on other metals
I know there is a reaction when doing the hard anno process and that the Caustic soda changes that process again due to it reacting to the alloy !
I have a tange nut with the hard anno on it - will try it when I get a chance
Doing it the way I did, there was quite some reaction - so please do it outside and safely :crazy2: ;D
please also post up if you try and find out any thing yourselves :daumenhoch:

I did this today on some black anodized Haro rims, worked a treat. I wore marigolds and glasses and used an old toothbrush. I put 3 litres of warm water into an old washing up basin and about 250-300 grammes of caustic soda (£1.50 from Wilkinsons) stirred it with a big screwdriver and put the rim in, left it to soak for 5 mins max, then used the toothbrush on it, kept rotating it and repeated the toothbrush method until I got back to where I started, took about 45 mins to strip 2 wheels.
I have polished one with Peek, one more to do.
Add Caustic Soda to water, not the other way round!!!!!!!!!
