Preserving latex tips

I have had several latex inflatable tips. I have liked them all but after a few years they turn dark and eventually get "sticky" and burst. I store them dry in the dark and use only KY on them so I assume their demise is due to body oil getting on them when I use them. My enemas when using them have been plain water.

I worry that washing them with many kinds of soap may do more harm than good due to some of the other things than soap that are contained in most soaps. I suppose detergent for cleaning after use might be a good bet since you are only trying to get oil off and are not worried about personal safety. Dertergents don't seem to contain skin softeners etc that could be oily, but I have not tried them.

It occurred to me that spraying the tip with the stuff you use on latex clothing to shine it (presumaby silicone) might seal the latex a bit and help keep the oil out but I have not found any support for that theory on the web. Do any of you know if that is worth doing or if there is something other than silicone that is "latex friendly" and might help serve as a barrier to oil? Or any other approaches to extending the life?

I suspect that with more than a few members of thid board enjoying latex as well as enemas I might get some good advice.

Latex will eventually turn dark, sticky and weak and will burst even without ever using any oil.

Susie- true enough, but I suspect if you could keep the oil from penetrating the surface and keep it out of the sun (which I do) that you could extend the usefull life considerably.

I don't think anyone keeps their balloon nozzles out in the sun for any time at all. it gets dried and put away.
