Colon tubes in mineral oil

A fair number of years ago before the vast array of E toys many soaked their colon tubes in mineral oil for a few days. The advantage was they would swell up as much as three times the diameter and become exceedingly soft. The down side was they would eventually deteriorate after about 6 months. Anyone else use this technique? (The good ol' days)

#1, why would you want to use anything that ruins your equipment? And #2, if you do that you might be exposing yourself to chemicals and toxins being released by the deteriorating equipment.

Greetings everyone

I've had the same two colon tubes for 14+ years - 38 fr - 36" long - closed end with double eyelets on each side - Red. I've always used liquid vitamin E. A great lube and the products still look and work like new. Typically they get used weekly.
