Oh yeah - Caustic is nasty $h!t. Came across a woman through my work years ago who had been renovating an old house - paint stripping using caustic. SHe had caustic in a soft drink bottle in the hall. Picked it up and drank it by mistake. Now drinks and eats through a tube in the side of her stomach...
If it's just removing anodising, why not use Mr Muscle oven cleaner? It'll bring it straight off - contains a weak blend of caustic in with other stuff.

Hey Christian,
Even Mr Muscle will pit the alloy if left on too long. I give it no more than 5 mins and then give it a rub with an old toothbrush. Leave it a little longer if it's not all coming away. Rinse it well in soapy water as soon as the colour is all off. Don't forget to wear gloves and don't splash it in your eyes. Then get ready to polish!
Oxalic Acid can make you a bit lazy with chemicals cause it's pretty much benign - stinky, but benign! Caustic will burn you!
