I know this is unnecessary (perhaps ridiculous), but I hate leaving loose ends.
To put the potential risks of handling cadmium in perspective, here is some information that is totally uninteresting, but pertinent.

Despite its toxicity, cadmium is still widely used in metal plating and several other industries, and workers' health and industrial waste are concerns.

In workplaces where there is risk of chronic cadmium exposure, typically for five or more hours daily, the cadmium level in the air is monitored and safe levels are established.

The greatest health concern is inhalation of particulates containing cadmium and cadmium compounds. Other routes of exposure are of lesser concern, although ingestion of 30 grams of cadmium (all at once) will likely kill you.

The corrosion of cadmium in the air yields cadmium oxide and, because of air pollutants, some cadmium sulfate. If you drop a corroded screw in hydrochloric acid you can see tiny bubbles and get the rotten-egg smell. The bubbles are hydrogen and hydrogen sulfide.

My opinion is that if you are concerned with handling cadmium corrosion products for health reasons, then mechanical removal is riskier because it is likely to produce airborne particles. Chemical removal would be safer. And if you feel that disposal of the chemical waste is an environmental concern, then you need to be equally concerned with disposal any solid waste from mechanical remove of cadmium corrosion products.

For purposes of accuracy and credibility, none of this information came from Wikipedia.
