--- Quote from: uc on September 21, 2018, 03:21:29 pm ---Dear all thanks for your support. Some feedback for you guys, I have not power up my equipment, agin, as your advice. I have contact my insuring company and that road could be another chapter. But I have open up the FLUKE 79iii and clean the board with alcohol. I did find some deposit that must be old and not related to my water problem. Now it works fine. I learn a lot I am “chicken out” to do the same action with my RIGOL DS1054X. And especial the more sensitive SIGLENT SDM3065X, refer to our Mr. tautech commet. I think I will await the reply from my insurance company. Take care. //uc --- End quote --- I would be careful mentioning your equipment starting and seemingly working to the insurance company. They may easily mistake the equipment for non defective, "mistake" meaning it's the cheapest route for them. It really isn't unreasonable to claim cleaning and calibration costs for everything that has been wet and that means most of it is written off. It turning on isn't any guarantee it still functions as intended short or long term. Of course, any self respecting insurance company will try to convince you that drying the equipment and using it as is is just fine and that they really won't and don't cover more than that. Most will try anything to avoid a payout. |

Be cautious in what you discuss with the insurance company. They may well claim that any damage to your instruments was due to improper post damage care, such as turning on prior to proper cleaning and drying. As to the arguments on how to clean that have come in this forum I will add a vote to the it varies and you have to know what you are working with. Vacuum tube gear. No, not necessarily good for dishwashing/spray cleaning. Paper capacitor packages. Bakelite junction strips and sockets. Many open switches. Many moisture traps. 60s transistor gear. Possibly a golden age for power cleaning, but there are many traps here too. I think we can all agree that residues from cleaning are possibly evil, that dried salts can collect moisture from the air and lead to corrosion and/or leakage paths. Many of us can tell many stories of successful cleaning of boards by the Pease method (I have even cleaned boards along with the dishes on occasion), and many of us can tell horror stories of cleanings that went wrong. Like one of mine where schmutz left between layers of a multi-layer board at manufacturer collected moisture during a cleaning that then survived more than one bake out cycle. Made a battery that played hob with circuit operation. Many of the differences in experience may result from the vast differences in water quality around the world. Where I currently live dissolved salts in my domestic water are a few dozen parts per million. At my previous location they were measured in parts per thousand. Tektronix location in Portland probably had some of the better water around. But I would have guessed that Pease location in the Bay area would have been closer to the other end of the scale. |

I frequently wash dirty boards out in the sink with dish soap and warm water. I normally let it dry for several days by a heat register though, or if I'm in a hurry I go over it with a hair dryer or put it in the oven on warm for a while. |

Will the insurer cover it? I can assure you they won't. |

Insurance is a different matter. If I were going to deal with insurance I would want the gear to be professionally refurbished, or declared a total loss and then buy it back from the insurance company for salvage value and repair it myself. |
