dann2707 Posted November 13, 2010 Report Share Posted November 13, 2010 As above really. What would be the procedure to remove anodising from my T-pro '06. I have 500g of "Drain cleaner with caustic soda" and just want advice on how to use it! I know to wear gloves and eye protection and do it outside somewhere ventilated but just not sure on how to use it. Cheers. Dan 1 Quote Link to comment Share on other sites More sharing options...
Ali C Posted November 13, 2010 Report Share Posted November 13, 2010 if it's the powder (the best form) then get a plastic container (not an old takaway rice tray as I found out) and fill with hot water (the hotter the stronger the reaction). Find an old toothbrush and apply to frame, wait a few moments and you'll see the frame reacting. Leave for as long as you dare and wash off with cold water.

dann2707 Posted November 13, 2010 Author Report Share Posted November 13, 2010 Looks like I have the wrong stuff with it not being pure caustic soda but a drain cleaner with caustic soda added to it. Nothing it happening to the frame at all I'll go hunting for some caustic soda proper tomorrow. Just unsure of where to find it! 1 Quote Link to comment Share on other sites More sharing options...

dann2707 Posted November 14, 2010 Author Report Share Posted November 14, 2010 I got some proper stuff from boots today, did the same procedure, added it all to hot water. It's barely even taken anything off! The only bit's I've noticed changed is inside the dropout mounts where the axle slides in. I'm guessing that layer of "anodising" has been effected by the removal of the axle etc. Just doesn't seem to be reacting at all :/ Looks like I may aswell just sand it down with some wet and dry and spray it straight on. Just a shame as I've wasted £4 on the stuff now 1 Quote Link to comment Share on other sites More sharing options...
Ali C Posted November 14, 2010 Report Share Posted November 14, 2010 if the annodising is thick, you may have to leave it longer to get the full reaction. When I have done stantions on sus forks before, it's been a real effort to get the annodising off Quote Link to comment Share on other sites More sharing options...
Bionic Balls Posted November 14, 2010 Report Share Posted November 14, 2010 if you induce a negative charge on the frame then it should speed it up... Get some batteries.. You'll need to find a bit with no anodizing to connect to.. Quote Link to comment Share on other sites More sharing options...
dann2707 Posted November 17, 2010 Author Report Share Posted November 17, 2010 Mr muscle oven cleaner has had no effect what so ever I think I made the caustic soda solution earlier too weak, as I filled my bin up half way with hot water. Gonna give it another go soon I think. Becoming a right pain this but I guess it's the only way to learn 1 Quote Link to comment Share on other sites More sharing options...

dann2707 Posted November 17, 2010 Author Report Share Posted November 17, 2010 I got a splash on my arm from where my coat didn't quite reach my hands, it hurt a little, this is what makes me think the solution was too diluted because I should have been screaming in pain right? 1 Quote Link to comment Share on other sites More sharing options...

dann2707 Posted November 17, 2010 Author Report Share Posted November 17, 2010 I will try it in a smaller tub then and see if i can get the solution stronger 1 Quote Link to comment Share on other sites More sharing options...
Revolver Posted November 17, 2010 Report Share Posted November 17, 2010 I believe this is the shit you shouldn't try to wash off - it makes it worse. Vinegar neutralises it. Quote Link to comment Share on other sites More sharing options...
dann2707 Posted November 17, 2010 Author Report Share Posted November 17, 2010 Any more tips before I start to do this tonight? I have 500g of it, do I add it all to a small container of hot/just boiled water, then scrub on with a tooth brush? Quote Link to comment Share on other sites More sharing options...
Ali C Posted November 17, 2010 Report Share Posted November 17, 2010 just put the hot water in the container (like an old jam jar) then add the powder until it starts to react (it will rumble and smoke a bit from my memory). then it's ready. It won't nearly be 500g of the stuff Quote Link to comment Share on other sites More sharing options...
Si-man Posted November 17, 2010 Report Share Posted November 17, 2010 Please don't breathe the gas in, can knock you out good and proper. Did some motorbike bars with some Caustic soda, only took about 15 minutes. Read what the does on the back says then just double it for more strength. Theres also a certain order to adding the contents to the container, like water/ caustic or caustic/water. Quote Link to comment Share on other sites More sharing options...
dann2707 Posted November 17, 2010 Author Report Share Posted November 17, 2010 (edited) "Progress" so far... if you can call it that. Been about an hour now and its working EVER so slightly :/ I thought it would take less time! Edited November 17, 2010 by dann2707 Quote Link to comment Share on other sites More sharing options...
Ali C Posted November 17, 2010 Report Share Posted November 17, 2010 was the solution you using steaming and rumbling? Quote Link to comment Share on other sites More sharing options...
dann2707 Posted November 17, 2010 Author Report Share Posted November 17, 2010 was the solution you using steaming and rumbling? It steamed and rumbled as I poured the soda in. Then it stopped rumbling after around 2 secs after pouring it in. Quote Link to comment Share on other sites More sharing options...
Ali C Posted November 17, 2010 Report Share Posted November 17, 2010 hmm, sounds normal, maybe it's pretty thick annodising. Quote Link to comment Share on other sites More sharing options...
LukasMcNeal Posted November 17, 2010 Report Share Posted November 17, 2010 U NEED MOR!!!!! I think it can't be concentrated enough Quote Link to comment Share on other sites More sharing options...
dann2707 Posted November 17, 2010 Author Report Share Posted November 17, 2010 Yeah seems like it might help the reaction if I rough up the surface with wire wool or sand paper first?If I put more in, it bubbles and overflows the beaker, already gone everywhere twice now, might have to put it in slowly this time though.
