Has your Klystra clear silicone bag turned yellow as it ages?

I've seen some pictures of clear silicone bags that appear to have yellowed over time. I'm not sure if these are Chinese knock -offs or real deal Klystra bags. Anyone?

Thanks,

YES! We have four genuine Klystra silicone bags and the older two have definitely yellowed.

They aren't bad looking, but they aren't clear and as translucent as when they were new. I don't think it is from any solutions that we have used, just aging of the silicone.

The bags are as strong and resilient as when they were new.

No wear and tear to be seen.

I have had one of the clear silicone Klystra bags since George originally started having them. Mine is actually a "second", in that there is a tiny bubble (really have to look for it) in the silicone. It started turning yellow within a year of getting it, but I figured it was natural for it to do so. It has never caused any other problems. I think it is just something in the silicon that turns with age and with air hitting it. It is still a good bag.

We have had the oldest of our silicone bags for about twenty years and it took about ten or twelve years to start turning yellowish.

My Klystra silicone bag has some evidence of discoloration, but not much. It just isn't as clear as it was when new. Certainly nothing compared to how surgical latex tubing changes color as it ages in use.

I've had only one rubber bag wear out, actually. My first enema bag, a Faultless combination, bought from a discount store in 1972. Eventually one of the shoulders by the neck cracked.

Mine is 15+ years old and has begun to yellow, too. I have attributed it to the oils in the Dr. Bronner's Peppermint soap I often use. No structural changes, hardening, cracks or other observable effects.

@bburl: If it's from soap, one would think there would be variation in the yellowing. In other words, is the bottom of the bag more yellow than the neck? Of course this could also be from heavy metals in water such as iron or copper. If it is a natural oxidative process of the material, then the yellowing should be somewhat uniform. Are parts of your bag more yellow than others? (the scientist in me wonders!)

Mine of course is relatively new and still clear. I should have purchased one years ago!

Mine has not started to yellow (about 3 or 4 years old) but does get cloudy/water spots/mineral deposits/whatever from city water. The bag is fairly easy to clean because I can get my hand in to dry it, but the tubing is tough to keep clear. Even so, it's great gear...well-made and strong. And doesn't get mold/mildew/yuck like the rubber stuff. And it's not bad for a decent enema....

Same yellowing problem with mine. was thinking a long soak in oxyclean might turn it a few shades lighter.

I have some discoloration in mine but it seems to be holding up pretty well. I think its mostly water/soap deposits.

I thought maybe using bleach in cleaning the bag might have been what caused the silicon to turn yellow; but I would rather have it yellow than not good and clean. Since it has done so evenly, it must be just a natural part of the silicon in the open air.
