What is the best way to clean the pins of tubes. I have some nice vintage tubes that got flooded and the pins now are coated by some crud. Would it be ok to use a sharp object to take off what seems to be baked soil on the pins?

1. I just wiped mine with a lint free microfiber cloth this morning - they were getting dusty. Is occasional dusting ok or a no-no?
2. I am told that the glass envelopes should NOT be touched with bare hands. Yet, my personal tube guru - Ambel, grabs them with sweaty hands and stuffs them in his trouser pockets! Is there consensus on how tubes should be handled?
3. Warm up - not for listening. But for those in storage or on unplayed gear. How long can we keep the tubes unused without having to pass some current through them? Jac of Jacmusic prescribes passing some current on tubes every ten years or so. What do you guys do?
4. Loose bases - can they be re-glued safely?
5. Maximum power on usage - is there a time limit on how long you can keep tubes powered up? Some SS gears have to be powered up 24x7. Are tubes the same?
6. How to store tubes - in dry boxes? Lock and lock with silica gel? Are they affected by humidity?

Most/If not all off your gear are SET, so the tubes are always biased to a high IDLE CURRENT, so even at idle this is the hardest time your tubes will be working, even at the loudest passages or usage the tubes are still at the same (or even less) as when idle. SOme say it is better to keep them on a 24-7, the thermal/electrical shock can be worst (keeping them on results in electric consumption). Tube life? Just luck! Some last forever...some last seconds!

All of my tubes were submerged by Ondoy and under water for more than 48 hours. Some of my peanut tubes suddenly became microphonic and un-usable. Would this be the result of the tubes being subjected to elements like water and dirt?

some possible scenarios.
1. Could the microphonic tubes been microphonic before the onset of Ondoy ?
2. Since the tubes were cleaned after Ondoy, some of the tubes could have dropped, bumped, shaken etc...I know you would handle them with care, I just don't know if someone else help you in the cleanup or in the collection of the tubes.
You could experiment with some cheap tubes
