It wouldn't corrode your sink in case of appropriate manipulations. Also, alcohol/alkaline mixture as well, very well decision. I can't say any exactly about their efficiency. I'm used to preparing solutions by myself for cleaning goals.

I can highly recommend the alkali/ethanol mix, and also an HCL/ethanol (1:4, my own creation) mix works wonderful, for disposal I just mix the two and add additional fresh water, and otherwise I save those in different containers and use those cleaning solutions several times.
The potassium permanganate solution also works, because there is a slight brown coloration that you get removed with the oxalic acid again, but is compared to the other two a little more complicated.

ok thanks, i will a try on alkali/ethanol and potassium permanganate, take a experiment
