I have an old stem i'd like to use on my survivor race bike i'm biulding but it's red (which won't fit the colour scheme) what's the best way to remove the anodising so i can polish the chrome under it?

Cheers Rob  :daumenhoch:

As above caustic soda is the way - be careful though it is dangerous stuff. Do not use hot or very warm water - cold or tepid is enough. The water will warm up through chemical reaction. Always add soda to water not the other way. Wear protective gloves and eyewear. Do not breath fumes. Caustic soda is a strong alkili, have vinegar nearby as a neutraliser. Use around a tablespoon to a litre or so. Summerge and agitate object for 15 - 20 seconds, rinse and evaluate. Repeat for 10 seconds and so on. To polish I would not use nylon washing up sponges or anything like that, best thing is metal polish wadding in the tin. Will not leave any scratches and gives a superb shine. And before stripping be aware some intricate areas of components can be very hard to get into and may leave tell tale areas of colour.

This may sound a bit fussy but it can be dangerous and people have harmed their sight using it.

Think i might just make do with the red then and cover it with a black pad??   :)
