I have not had rodents in my equipment, but every few years I completely disassemble my desktop computer. I do it outdoors on very hot sunny summer days. I first remove all drives and set them aside. Then I unplug all the boards, and blast each board with water using the garden hose. I do the same with the motherboard, and I open the power supply and blast that with water (that's where most of the dirt is). Then I leave all of it sit in the hot sun all day long to completely dry. The drives should not get soaked. Those I dust off with a fine dry scrub brush, and wipe the outer case with a damp rag. I always take the CPU and CPU cooler off the motherboard too, so water dont stay below it. (I apply new heat transfer grease to the CPU when I reassemble). Than I reassemble the whole computer. It always works fine. The computer I am using right now has had this done to it several times now. The key is making 100% sure all water is gone before using it. Anyhow, if rodents were in some equipment, I'd surely wash everything with a strong blast of water. But I would not soak switches and pots. If a little water gets in, that should be ok, but dont "flood" them. I should mention that this began when I acquired several computers that were in a flood. The drives were trash, ALL OF THEM, including Hard Drives, FLoppy Drives and CD Drives. The boards were covered with mud. I opened them, hosed them very well, and after drying, I reassembled. They all worked fine, but I had to replace the drives. |

Is this something we really need to be mindful of? I worked in a factory once that did a lot of cleaning of electronic modules. Air was supplied by a central compressor. I never had a problem with static and I don't think anyone else did but how would we have known as many of the modules were already faulty.

Is this something we really need to be mindful of? I've used a 1KW handheld Martindale blower for decades, no known static problem ,just occassional physical breakage of shielding or something like that, because of the air pressure involved, blowing out tarry/greasy/hairy crud. |
