I can see that line of reasoning..same reason there is a picture of a foot getting cut off on a lawnmower and Preparation H says don't take internally.

For the record, I didn't use really hot water and I only used a half a cap full of bleach. Once I washed it with dish soap and water...really good. I filled again, added the bleach and shook well..allowing it to sit for about 30 minutes..then empty, rinse well again and now they are full and frozen.

I have used the hospital irrigation bottles in the past and they are great!!! Finding a supply is hard...you have to know the right people.

Thanks for the info everyone..
