Help required before I make a mistake.
If I want to strip an anodised part can I just use some paint stripper or will I just make a mess?
You have to sand or blast the anodizing off first, then polish. It's easier to powder coat over the top if you want paint finish.
Thanks, but not what I wanted to hear.
I've used Oven Pride BBQ & Oven Cleaner from Tesco. Poured it into a plastic takeaway container, finished the chinese first. It comes with protective gloves. Do it outside, fumes are BAD for you. When the item to be "cleaned" is placed in it, it effervesces slightly, giving off hydrogen I think so no smoking! I used an old toothbrush to assist the process. You can see the coloured anodizing coming off. It was pretty straightforward, only taking about 10 minutes.
Caustic soda.
Good tips.
I will see how I get on with some oven cleaner!
Cheers
+1 for the oven cleaner
leave it for 45 mins and hey presto
When you do this, what state does it leave the aluminium in? Is is dull and pitted, or just dull and in need of polish?
The blue lockout on my forks clashes terribly with the rest of the bike 😉
It is a bit dull so polish it with solvol and duraglit
The shiny bit was black anodised

As instructed I tried the Oven/BBQ cleaner. A lot of white froth convinced me my aluminium link had all but disappeared ( not helped by the instructions excluding use on aluminium).
However, success- anodising came off and the aluminium left. Dull white but not pitted. Quick polish with Autosol from aluminium racing car days and bingo!
Really easy and really good.
Best forum advice I have ever received. In fact the only useful forum advice ever received.
Thanks
Will it not react with oxygen?
i wouldn't be over concerned with oxidisation, keep a layer of autosol on them every now and then should be fine.
caustic soda
1 molar solution
bubbles off
sorted
my failed year of a level chemistry did come in useful
