Hard Anodising

(1/3) > >>

BENDYCAT ELEVENTEEN:
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  ;)

pkripster:
nasty stuff aint it :daumenhoch:

NORTY40:
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 !!

BENDYCAT ELEVENTEEN:
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 ?  ???

insectbones:
Good bit of info for impatient me.

What do you rinse the stuff off with after?
