Youd better make sure you get all the bleach out as bleach and corks equals cork taint!
Yup, TCA is a real problem for which there is no fix. Just 3 parts per
Trillion can leave your wine smelling and tasting like damp newspaper. If you are thinking of using bleach, DON'T! Go with some sort of Oxy cleaner instead.
If you have already used bleach, Then I would advise that you find another place to store your corks (sealed and as far from bleach as possible).
TCA forms when three elements come together. Mold, Chlorine, and Pheonals (chemicals found in fire retardants and wood preservatives), can combine to form TCA compounds. If you have no pheonals, or any population of mold in the vacinity of your wine, then you may not have much to worry about.
Even though the odds are that you do not have any potential problem, you need to remember that TCA only needs to exist in the smallest, most minute amounts to have a very drastic effect on your wine. It is better to be safe than sorry. Avoid the bleach!.
