Hence, the "Corkidor". I do the same thing with a small one gallon bucket and a strainer which is held off the bottom by a couple of plastic pegs superglued in place to keep it above the sulfite solution. Thousands of bottles, not one problem thus far. (knock on wood)I suggest that the time and cost to sanitize the corks is a miniscule investment compared to the potential (albeit small) problems of contaminated corks. I have an old salad spinner that I have adapted for this purpose. It is the three piece design with bowl, basket and top (see pictures). I pour a small amount of sanitizing solution (3T of K-meta in 1 G of Water) in the bowl, put the corks in the basket and cover with the top when I start a bottling session. While I am cleaning and sanitizing the bottles and filling them, the gas from the solution does its job. The corks are suspended in the gas for about an hour.
