Yes that is true, you'll have to take it out and clean it once in a while, the lead can clog the ports and cause a wrong reading, had to do this on my srt4 when I ran 110 leaded, would just pull it and carb clean it
That detail is good to know (that they can be cleaned)
The impression I got was that cleaning would probably ruin the sensor, so it's nice to find that it probably won't.
We'll call it that it could ruin the sensor, but probably won't. :D
