It’s also a useful chemical for a plethora of laboratory tasks ranging from basic sterilization to removing labels from old pieces of hardware.Ĭleaning electronics with ethanol requires a different reagent grade than for the ethanol intended for routine laboratory use, however, so the ethanol purchased for cleaning electronics will probably be a different item in the lab’s inventory regardless of what else is on hand. While ethanol isn’t a strong solvent, it is typically sufficiently powerful to clean sensitive electronics which may have accumulated light layers of corrosion or dirt. However, when exposed to the wrong cleaning solution, even the hard plastic of PCBs can corrode-and manufacturers are rarely willing to replacing a damaged PCB as cheaply as they might replace a sensor or semiconductor component.Įthyl alcohol is a great choice for cleaning electronics in the laboratory because it’s inexpensive, mineral-free, and evaporates quickly.

The printed circuit board plastics of electronic components are typically the hardiest part of any laboratory hardware. While sensors tend to be slightly more hardy because they are exposed to a partially uncontrolled environment to fulfill their core purpose, most pieces of laboratory hardware have sensors which are highly sensitive, making even minor disruptions to their functioning relatively hazardous to their output of clean data. If water bearing minute quantities of dissolved minerals splashes onto an exposed semiconductor, it will be nearly impossible to remove the trace minerals which will disrupt electron flow. Of these components, it is typically sensors and exposed semiconductor materials which are the most vulnerable to damage by using the incorrect cleaning solution.
