Yes. Don't get it in your eye. It's probably a good disinfectant for wounds but man does it sting. That was sarcasm by the way. You don't want to get it on your skin. If you do you'll need some of this:

EPC light came on again and then the CEL......scanned it....same camshaft position sensor came on for sensor B Bank 1...
Why would it fire that code again?
Yes, as others have been mentioning, try contact cleaner. And as I found out on the W12, also don't assume the wiring itself is in order around a given connector just because it looks coherent. Some/many of the sensor wires use very fine gauge wire and are already very sensitive to what they read for slight differences in ohms, volts, etc. Meantime the wires can get stretched or break internally just with jostling of maintenance let alone abuse, connectors may not be crimped well enough to avoid internal corrosion, etc. Thus on W12 now proven fix both per TSB and one field experience is to replace connector wiring with O2 sensor issues, as opposed to the sensor itself. But very fiddling to try to actually assess electrically, so at some point you just make an educated guess and perform the surgery. But playing with contact cleaner to see if there is any improvement is a helpful pointer, even if it does not resolve fully without replacing connector or the terminal wiring in and close to it.
Need to look up the way the sensor actually functions (voltage, amps, ohms, pulse, etc.). You should be considering wiring around sensor and also the underlying function--cam adjuster--as suspects too. One other suggestion given prior confusion on which one was which is simply unplug the one you have focused on. See if it comes back instantly with a fail code for that sensor or connection, or whether it actually now flags a different one. Obviously then it will flesh out that the identification of which one it actually is needs to be revisited.
In addition, I would take that specific code and point a search engine at it and then look for posts on Audiworld, audizine and perhaps a few others. Doesn't really matter which motor generically if the sensoring set up and function are similar. You may have to tweak the search some--the P code vs. the VCDS code, whether to put the text of it in, etc. What I do when the code is not familiar or the underlying possible causes varied.
