Well, even though the excessive de-chorinator isn’t gonna hurt anything, and after using bleach, I always go overboard, that doesn’t mean the more the better. Dechlorinated is pretty expensive so it can be a waste of money. I would just use a little more than the recommended amount for your equipment soak and then test the water to see if there’s any amount of chlorine in it. If you detect chlorine, then add some more.
