Cleaning Stereo Equipment, TV's and Computers
Dusting verses Washing
Dry dusting the top of a stereo receiver, cable boxes, modems or the back of TV's and other electrical components is not a good thing to be doing. Like with a feather duster. There are many open air vents at the top of them or on the sides of for the unit to stay cool and to allow air to move through them for this very reason. Besides the static electricity it creates, dusting with a dry cloth or with a feather duster will cause much of that dust and dirt to be pushed into those open air vents, falling into the unit.
Using a very damp, completely wrung out, soapy soft cloth will capture most of that dust, preventing that very thing from happening. With slow cautionary cleanings of. Wiping the dust up and away from the unit, rather than applying pressure down onto it, as most wiping entails. Bringing the dust up with shorter wipings of, not pushing it across and eventually down into those air vents. Then causing that dust to be falling onto the electrical components inside of the system. Which acts as an insulator, making it harder for them to stay cool and not overheat.
Or washing down, not dusting a TV screen. Especially with the newer smart TV's that are commonplace in homes these days. Using the right solutions to be doing so with. They are not only very sensitive to most types of detergents, but also to the pressure that's being applied to them when cleaning/washing them, being easily damaged or scratched.
