Hi there guys, I'm new to this forum and I totally ruined my Plastic Komplete Kontrol Keybed midi Keyboard thanks to my damned self.

I wanted to know if anyone has experience remove food stains off keyboards. And before you ask why I had food right next to my instrument, is because I don't live a luxury life, and have limited space. I digress. If anyone ever used Hydrogen Pyroxide to remove food stains off the keybed of a keyboard please do let me know, usually with Youtube there's guides for literally everything but this.

Please help.

hydrogen peroxide with UV light or under direct sunlight should work perfectly fine. You need to submerge the keys in the peroxide and leave them under UV or direct sunlight for a day or so. Google about it.

If you use a cream version, you need to plastic wrap it.

Hydrogen peroxide is usually 2% peroxide and 98% water. Do you want to be washing your keyboard with water? I wouldn't.

BTW ... what kind of food stains?

It's actually fruit, and it has a nasty pink tint on the key, it's just one key but its killing me.

I used Dettol wipes and water and everything I can think of but to no avail.

Also, if I isolate the treatment shouldn't it be fine?

usually vinegar or citric acid is fine for removing fruit stains from clothes and fabrics.
You could try if it works with the tint on your keyboard.
Just soak a Kleenex with vinegar (in your case probably clear vinegar, not Balsamico or another dark coloured one) or with lemon juice and put the Kleenex on the keys for a few hours.
Just make sure not to soak the Kleenex to much so that the liquid will run into the keyboard!

No MacMacMac. This is how it's done:



If the keys are wooden, then you need to cover the wooden parts and apply the cream/paste version. Something like this:

Ask your lady, she'll help you with it.

As per Abdol, you could also try toothpaste on a cloth, gently.

So, in the end there are then black keys, white keys and one extra white key that sticks out. Maybe even more than the stain. 😉

Are spare part keys available?
