Why do I keep ruining probes

    Ok I keep buying the cheap white probe battery thermometers. I'm sure you all know the 14.99 jobs at any walmart/ hardware store. I've about had it with them and am getting ready to buy a more expensive hopefully better lasting/ working one. Before I buy one though my question is am I ruining these cheapos somehow by washing them or are they just junk. I also got a thermopen for xmas I'm afraid to use. Its ok to wash the probes gently with soapy water isn't it? I think I made the mistake of ruining one by scrubbing the probe too hard but it's ok to get them wet right? Or should I just use alcohol pads? Thanks Guys ben

    Don't wash them, just use the alcohol wipes. Water wrecks the electric bits.

    Same for the thermopen then too? Perfectly safe to if the probe has been used in a longer cook, just use a pad or 2 then put away? Last question, which temp probes should I be looking into?

    As long as you don't get the junction where the wire enters the probe wet, you should be fine. I use my Thermapen every day, and alcohol swabs aren't free. I just wipe it with a soapy sponge and then rinse under the tap. Again, JUST the probe. My Maverick gets the same treatment.
     
  6. I use the Walmart cheepos on occasion, wash the probes with soap and water, dry thoroughly and have had no problems with them...Just be gentle and they should function fine.

    Good Luck,

    Same here. The probe on my MAV 732 only goes in the meat to the bend, so that is as far as water ever touches the probe. Nowhere near where the wires enters the probe jacket...JJ

    I scrub mine with Mrs Bear's scrub sponges & rinse them off.

    Just NEVER get water in the junction of the cable & the probe.

    Then I only wipe the meat probe with an alcohol wipe just before inserting it into any meat.

    Just plain rubbing alcohol on a paper towel, or in some cases a scrubbie is needed. Like the others said the critical point is where the wire goes into the probe. That can't get wet.

    I only wash with a soapy sponge and warm water the probe part that go into the meat. I stay away from where the wire connects. I also wash the probe I use to monitor the smoker temp since that gets covered with smoke soot. I own a Maverick ET-733 and have been using its original probes for about 2 years.

    Should I say it again?  No water near the wire?

    I have a bad habit of leaving my Maverick smoke pit temp probe out with the smoker.  This time of year, IF we get any rain, we have humid and foggy weather.  I might have to bring the pit temp probe and in for an hour or so in a 200 degree oven to dry it out.  Also, for those that don't?  It is a good idea to clean the pit temp probe occasionally to avoid faulty temp readings. A good cleaning of the jack that enters the control unit is also helpful. My Maverick is very finicky about the jack being inserted fully as there is no familiar "snap" feel that I am accustomed to.

    I should add that in my years of using Mavericks, I have only had one faulty meat temp probe.  I have also had cheapie Acu-Rite therms for years, and have never had a probe problem with them.

    Good luck and good smoking.

    The probe tip sits in the water of the meat without harm, but it's where the leads go into the probe I'd worry about getting moisture into.  (And mechanical stresses too.)  The metal braiding gives some strength and thermal insulation to the leads inside but it's not water-proof.  

    And I've had some appear toast (read way too low or too high) and then have them come back into calibration after a couple more uses or thermal cycles.  So I don't just throw the bad ones away like I used to but give them a few extra chances and just label the read-out as NG until I trust them again.  

    And the $8 Ikea ones seem to be just as reliable as anything else, and they have a F/C switch which most of the cheap ebay ones don't.  

    Hopefully that last statement won't hi-jack the thread too much.

    You can add about a 1 1/2" of shrink wrap at the joint to help protect it from incidental water contact. But do make every effort to keep them dry.
