Let's not forget that the plastics themselves give off potentially harmful chemicals too as they slowly biodegrade due to oxidation and other matter-aging processes. I still use plastics for the first couple years and have never had a problem, so these plastic-ingredient/manufacture chemicals probably aren't too unsafe. We all drink from plastic cups occasionally, right?
Just something to ponder. I think that alligators are extremely durable and are undoubtedly less vulnerable to chemical hazzards than we are. Besides, as to the original question,. I really don't think that dish soap contains toxic chemicals. I could be wrong of course, but I have drank it by accident before and other than tasting just awful, I was fine. I personally don't think you need to worry about soaps, but would of course advise you to rinse as much out as possible before returning the animal/s to the environment.
>>Just remember that plastic is porous and that you will never get all of the chemicals out of it. I would recommend using the aquarium cleaners they sell in pet stores that won't harm your animals...
