Francesco,

As far as I know, Sodium Hydroxide will not etch iron. Did you mean NitAl (Nitric acid + Alcohol)?

>>Ethanol at 96% works fine?
>>I have to use distilled water or normal water?

>>For 100ml of solution I have to use 70ml of ethanol and 30ml of water, is

>>How many grams (or spoons) of NaOh I have to use?
>>How many days I have to leave the slice in the solution? 7-10 days? In this
>>period I have to change the solution or the first potion works fine for all
>>these days?
>>
>>And after? What I have to do? I have to wash it with ethanol and after dry
>>up in oven, 80°C?
>>After could I also put some rust prevent varnish?
>>
