    To maintain the integrity of the o-rings, I use the Commando charging dock 99.9% of the time. I also take the phone in my PFD when kayak fishing in saltwater. Over time, the contacts have become tarnished at times (green buildup), where I can't get it to charge. The only solution I've found is to use a metal dental pick to scrape it off, but I'm not really keen on scraping metal to metal over a long term.

    Does anyone know of any cleansers that would be effective without damaging the plastic case? This is such a small, recessed area, that it's hard to get anything in there to "buff it it out". Thanks.

    I've done this too, but these are pretty small recessed contacts. I've ordered something from Amazon. I'll post a follow-up.

    I got this in today:
    Amazon.com: DeoxIT, 25cc Precision Dispenser

    It works extremely well, and has solved this problem. You apply, wipe off the oxidation, then repeat as necessary. It's slightly oily, so it's supposed to leave a protective coating. Not sure how well that will last, but you use so little that the the bottle should last half a lifetime.

    I used a q-tip and wiped it a few times with tap water. Have to do it every month or so, depending on how dirty I get it.
