yeah just go get a 1/2" or smaller piece of copper pipe about 36" long clean it well as you would anything coming in contact with your wine then stir with it.
it may be a pricey spoon but it will take care of your issues most likely, test with the penny first though
I wrote about Reduless and a copper scrub pad, but with the last batch I had, which developed H2S, a copper pipe was exactly what I used. I bought a new, clean short copper tube, sanitized it and actually splash racked through it. I still had some smell, so I used the pipe to stir the wine and racked again.
That works pretty well, but with the several (splash) rackings it takes, the wine can get damaged in the process. That's why I really like the Reduless; it does its work quickly, thoroughly and doesn't put the wine through so much stress.
Not always but generally speaking, H2S is caused by something the winemaker did that wasn't exactly what the wine needed. It many times is a result of the yeast getting stressed from lack of nutrients or a temperature issue. Ultimately, one's aim should be to avoid this, so getting rid of the smell won't be a factor.
Nutrients are not an issue with wine kits unless the kit comes with a nutrient packet. However, with non-kit wines, nutrients are very, very important.
