If you want to choose the best type of cleaning swab for electronics, you need to consider the item you are trying to clean. Cotton swabs are often a good choice for cleaning certain electronics, but cotton balls will typically leave too much debris behind, or generate excess static electricity. If you are working around delicate electronic components, such as inside a computer case, then you may want to consider a cleaning swab that has an anti-static foam tip. For really big jobs, such as cleaning a television cabinet or screen, you may want to choose a microfiber cloth instead of a cleaning swab.
There are many different contaminants that must be cleaned off of electronics from time to time, some of which require cleaning swabs. Dust and liquids are two common substances that can effectively be dealt with by the right type of swab. The main types of cleaning swabs for electronics are cotton and foam, though foam-covered cotton also exists. In order to choose the best type of cleaning swab, it is necessary to consider the type of device you are cleaning in addition to what you are cleaning off of it.
Dust can be a major issue with electronics of all types, and it can settle on everything from television screens to the internal components of computers. Large surfaces, such as television screens and computer monitors, are typically better suited to microfiber cloths, and electrostatic dusters, than small swabs. It is often necessary, thought, to use a cleaning swab to get into the small crevices present in these types of electronics. In that case, a cotton swab will typically do the job, though you should be careful to not poke dust deeper inside vent holes if your swab is too narrow.
Some types of swabs are very well suited to cleaning dust from the insides of computers and other electronic devices. Cotton swabs are typically good for cleaning out cases, though you may want to find a swab with an anti-static foam tip if you are doing delicate work on circuit boards. You may also want to use a blower or vacuum to remove the bulk of the dust before using swabs for the final cleanup.
Cotton swabs are typically the best choice for cleaning up spilled liquids. After any type of liquid spill, it is typically a good idea to soak up the liquid if at all possible. Cotton swabs or cotton balls can be used for this purpose, though balls may leave too much debris behind. After the liquid has dried, you may also want to consider cleaning up the residue with a little isopropyl alcohol on a cotton swab. Foam tipped swabs typically are not well suited to liquid spills, since they are not as absorbent, and may dissolve in alcohol.
