I actually have quite a few jelly toys, and it is one of my favorite materials. I have yet to have one deteriorate. I don't use lubes with them (don't need it) And I wash them constantly, When I a done with them they get washed and air dried then cleaned once a week no matter what and then again before use. I use medium water and a light soap. I have never had one deteriorate or causer an infection so I keep going with it.
