I just got a new milwaukee ph controller, but the electrode is dried out it says to use a special soaking solution that you have to buy from them. I'm just woundering if there is any home maid concocktions, I can use instead.

I found this information:

The glass pH sensing membrane may also require service in some applications. This membrane can become dehydrated or coated with a thin layer of deposits. The best procedure for cleaning or rehydrating the glass is to soak the probe in a pH buffer of 4.0 for several hours. If this does not work then immersing the probe in hot buffer 4.0 solution will usually work.

I don't know how far you can push that "dehydrated" part :razz:

Personally I always thought once they get dry (ie. more then a couple minutes out of liquid, they were dead.
