At one point a few months ago I was in a pinch for a few days, and I just used one hydrophilic catheter per day (speedecath by coloplast) and my "sanitation" technique was to just run it under scalding faucet water for a minute or so, let it just cool down and then stick it in...

Obviously not ideal, but I didn't get a UTI from that little experiment and still got all of the luxuriously slick treatment that makes a hydrophilic catheter such a treat. I can feel down there, so this is very important to me.

Anyhoo, I just wanted to compare notes and see if anyone makes a habit of re-using hydrophilic catheters on a regular basis and if they have any techniques to share.
