Let's clean this MIDI keyboard or electronic piano. We can see that the keys are a little yellow.
As it is an electronic keyboard we should open it and separate the electronic parts from the mechanics, since circuits and liquids do not get along very well.
However, as it is not very yellow, it may not be worth the complex and "risky" task of disassembling and assembling it.
Of course, we must be very careful when applying the cleaning product. First, we do a basic clean with an alcohol-soaked, damp white cloth. Make sure it’s not wet so that no liquid enters under the keys.
With a dry brush and a vacuum cleaner we clean the spaces at the back of the keyboard.
To bleach the plastic keys we will try using an oxidizing cream 30 volumes.
We must protect our hands with gloves, since the cream can damage skin, and be careful not to use it on wooden or ivory keys.
We are going to try on a few keys like this…
It is applied key by key to only the white keys, using a cotton wool ball with a very small amount of cream while again, being very careful so that nothing gets inside the keyboard. If the cream gets into the gaps, it will probably damage the inner mechanism.
The cream we used can be found in any drugstore, it is like hydrogen peroxide in a cream format, it is used by hairdressers and it is quite cheap.
Once applied, cover it with a plastic and place it in the sun for a few hours. Although it is winter now, to avoid problems, we try to only get the sun on the area we want.
The time in the sun depends on how yellow the keys are.
After a while has passed, we proceed to clean it with a damp cloth soaked in water to remove the remains of the cream.
We can see that the keys are whiter and that still have their natural brightness, but we will repeat the process to try to bleach them even more.
Now, it’s much better!. So we will repeat the process with the rest of the keyboard!
And enjoy again.
Thank you!.
