To avoid short circuiting, make sure that you unplug the audio equipment before starting the cleaning. By that, one does not mean turning the source off, but separating the equipment entirely from the plug-in outlet.
Make sure that you have the necessary supplies or things to clean the audio equipment. This may include an audio cleaning spray, portable vacuum, screw driver. You don’t want to waste time searching these items or rushing to the nearby store once you have begun the process. Ensure that everything is within reach.
Remove the outer cover of the audio equipment, which shields the inner area. This can easily be removed by unlocking the bolts or screws, which can be done with the help of an appropriate screw driver. Locate the screws and set them aside. Don’t lose them as they will be required later on.
You will find that the inner components are particularly dusty. Now use the can of compressed air to blow or clear away the dust. Apply it to all rusty areas. The inner part is very delicate, so do not use a cloth to wipe the dust. The resulting damage can make the device unusable for future purposes. You can further use the vacuum cleaner with the necessary attachment to vacuum away the dust.
In order to remove grease, or corrosion, apply a contact cleaner to all the internal parts. Make sure to spray it rigorously and leave it to dry for a couple of hours. Don’t try to wipe it off on your own. A contact cleaner typically comes in handy when cleaning pots or knobs. After applying it, work the knobs to ensure that the corrosion is eliminated completely. Do the same exercise when it comes to cleaning faders, push buttons etc. Ideally leave them to dry but you can further wipe any excess with a cloth.
Put on the component cases by gently screwing the bolts you had removed earlier. Now plug-in the device and test it.
