Why can't it be re-ano'd does it leave it blochy ?

the best way i can describe it is that it leave little dots all over it . with little pin holes in the new ano . the oven cleaner or drain cleaner will contaminate the aluminum . it is VERY hard for them to get it clean after someone does this . but as stated before . if you are going for a raw or polished look it works awesome .

Just to clarify...

I know most people will use oven cleaner but if not watched very carefully it will damage your substrate alloy. So the best way to do it, is how the pro's do it. With Sodium Hydroxide. AKA Lye AKA Caustic Soda. Which happens to be the main ingredient in oven cleaner.
If you have used oven cleaner before and you noticed that your part is splotchy, that's  pitting of the metal from the Glycol ether's in oven cleaner.

Drain cleaners that are pure sodium hydroxide will not pit the alloy... therefore you are able to re-anno if you strip using 100% sodium hydroxide and water.

the glycol ethers in oven cleaner pit the alloy there for making it difficult to get a good anodization on the parts.

Re: HOW TO ** Remove Anodization **

i plan to try this soon deme im just waiting on some gloves i ordered.what about say if i wanted to remove the gold anno from my nipples on my rims is it theoretically possible that i could just slowly turn the rim in a shallow wide bucket full of your solution and it will make the gold come off? what any rubber on the rim will it eat it up? like if i leave the rim strips on or something.are they safe?

Re: HOW TO ** Remove Anodization **

first the rims are they aluminum or steel? I would assume they are aluminum so not only will you be striping the nipples but the rim itself.

also you could turn the rim in the solution but I would be very mindful of any solution running down the spokes and removing the anno on the hubs (if they are aluminum). post up some pics of what we are working with and that may help more...

okay let me get the draino first.i just got the gloves now.i will take pics of how the cages come out then i will concentrate on the gold nipples.i wanted to use a shallow bucket so it wouldnt go hub deep but they are 24" rims so that would be difficult.so when you say stripping the aluminum also what exactly does stripped aluminum look like maybe i want that look cool

it works fine on something new.my pedals ^^ up there were brand new before i did it.i think they just get blacker the newer the anodizing is but dont worry it comes off.need super fine steel wool and nevr dull to do what i did.if you add the sanding with super fine sandpaper step before polishing you will get even more shinier results like that dk stem up there which is sicck.

Yes it will strip the ano off no matter if they are new or well used.

Re: HOW TO ** Remove Anodization **

Interesting thread here... Good work Deme.

I'm such a 70's guy it's pathetic. I have no anno stuff at all. However, I did inherit one little seat post clamp on a bike I purchased that was blue anno aluminum.

Just for fun I let it soak in plain white vinegar overnight and later the next day when i came home from work, I pulled it out the anno was completely gone.

Is it possible that regular old vinegar soaking can remove anno quite easily as well? It sure did on that blue seat clamp... I was quite surprised.


A "Squonk" is like a Mongoose only much harder to find...

Re: HOW TO ** Remove Anodization **

Another product that works for de anodizing parts, especially small ones, is Greased Lightning Cleaner and Degreaser.  You can find it in Home Depot in a yellow gallon jug.  I took a set of faded gold anodized super maxy cranks and sprocket, put the pieces in a gallon ziplock bag with enough Greased Lightning to cover.  Agitated the bag a few times and in about 10 mins all the gold was gone.  When your done you just empty the bag in the sink and throw the bag away or reuse it later.  No nasty fumes either.  I think it was about $8 for a gallon of the stuff.  Worked really good though.

Re: HOW TO ** Remove Anodization **

I have heard that Muratic plumber's acid (31% Hydrochloric Acid) works but I have not tried it. Has anyone tried this???
I don't want to risk my parts to a chemical that smokes when you open the bottle. and it has a really strong odor.

I would stay away from Muratic acid. It can be nasty stuff if your not careful. Muratic acid might work but I have not tried it on any parts. Besides why use HCL when Caustic Soda will do the same job.
