    Any strong alkali.

    Caustic soda is very good

    Caustic soda.

    A table spoon of soda per 0,5 dl will do, the warmer the water the better.

    If the solution is not very strong you will be able remove the colour without completely remove the oxide of the anodise.

    oven cleaner does it , you will probably have to buff it up a bit afterwards.
    slowly heating and cooling it with a torch will do it ,just don't melt the bugger .

    Yeah, I use caustic soda & warm water. If you do, use gloves & be very careful not to get it on anything else.v & don't breathe in the fumes.

    Good advice , but I think you add the caustic to the water , not the other way round . Please confirm.

    Yes, but it's caustic so burns the skin :) so use gloves.. & don't splash it about.. Lifts anodising in no time at all.Also I imagine the fumes aren't too good for you either..

    Won't caustic soda damage the alloy underneath as well though? Be a shame to come back and find a bowl of Aluminium soup. :p

    You ALWAYS add caustic to water, NEVER the other way round. Sorry to shout but this is very important.

    Caustic burns are worse in many ways than acid burns. Can we have eye protection and gloves please.

    And use cold water; adding the caustic granules causes the solution to warm up anyway. If you add it to already warm or hot water and get localised boiling it will spit everywhere.

    The voice of experience, this is. I was inspecting some equipment in a milk processing plant some years ago and the stainless steel pipelines had just been hot caustic cleaned. One of the pipe unions wasn't tight, and about a teaspoon of caustic liquid sploshed onto my head. I wasn't wearing a plastic helmet as it wasn't that kind of risk zone.

    I knew instinctively what had happened, even before the hurt started, and I ran to the nearest fire bucket and plunged my head into the water.

    The next day a chunk of hair about the size of a 2 inch paint brush fell out. :eek:

    Caustic soda is stuff to treat with a lot of caution and respect.

    I use soda and it works of course there are the common sense rules, use gloves, eye protection, in a ventilated areas etc, like it was referred by some also is good to have some acid close in case an accident happen or you want to stop the reaction for that I use vinegar.
