Key ONE - All Purpose Cleaner

I was a bit sceptical on whether or not this product would work or not, since there where no online reviews, but I choose to give it a try anyway. I first used this product on an old used keyboard that I used when I first started playing 6 years ago. The instrument was very dusty, but when I used Key One it manged to remove all the dust from it, It even manged to remove a smudge that the keyboard had since the day i bought it and was never able to remove it using home cleaning solutions. Impressed with this result I proceeded to use it on my other two keyboards. After giving my two keyboards the full works, they were left looking like the day I got them . Granted scratches will still stay, but they are only visible under bright lights and from an angle, so they are not really noticeable The solution does not leave the keys feeling sticky or greasy. It also has a nice aroma that I can only describe as that smell you smell when you go to a music store that has a piano room. The smell is not strong though and it's not permanent. Overall Key One is a really great product that works and I will definitely buy it again when I need more of it.

The spray mechanism allows it to spread out or spray close to concentrate it.

A little pricey, but works well. I use it very sparingly and rub lightly on the keyboard. So far, the board-printed info hasn't rubbed off and this cleans effectively. On the other hand, plain old water seems to work well, too, although I seem to have to scrub a little harder to get it clean with water than I do with this product.

I recently bought a so called "Like New, Mint, Never Gigged" Keyboard Synth from Ebay. Opened it up & nearly puked!!! It was stained with Soda, Coffee, what looked like permanet smudges & God knows what else, the Seller didn't even clean or detailed it. I looked up Keyboard Cleaners & found this brand not many reviews, but the whole marketing / look of this product looked very legit, so I bought it spent 20 minutes detailing my Synth & when done I was blown away the Synth looks totally brand new!!! also this is safe for people with Chemical Sensativies+++ This Works - Buy it -

Easy and keeps my keyboard keys clean

Don't bother with the other brands. This is the best. I have been a piano teacher for 36 years. This is the best product for polishing and cleaning.

From now on I won't use anything else to clean my keyboards. This product is absolutely the best. Used it on all of my digital boards and synths then tried it on the keys on my acoustic piano. One of my older boards is a Yamaha MOXF8 which has a Matt finish. Sprayed some on a microfiber cloth and wiped the keyboard and it looks brand new. From now on I won't use anything else.

I left my keyboard unused and without a cover for much too long and using a regular microfiber cloth wasn't cutting it. This spray got the dust off in one go and didn't leave any residue. Couldn't even tell I'd left it abandoned for so long! It looked brand new after.

Puede ser muy buen producto pero el vendedor le ha pegado una etiqueta en alemán y las instrucciones en inglés son inaccesibles. El vendedor no piensa mucho si lo pone a la venta en el mercado internacional.

It cleaned up my keyboard and digital piano keys giving them a glossy feeling. Time will tell how well it works as a protectant.

Sehr gutes Reinigungsspray für Klaviertasten. Ich nutze es in regelmäßigen Abständen zur Reinigung der Tasten meines Yamaha E-Pianos. Es eignet sich hierfür sehr gut und hinterlässt ohne großen Aufwand sehr saubere Tasten, die sich nach der Reinigung auch noch sehr gut anfühlen. Das Spray schadet der Oberfläche der Tasten nicht. Das Spray ist ergiebig. Die Flasche wird also eine ganze Weile halten. Sollte sie irgendwann aufgebraucht sein, werde ich wieder dieses Spray kaufen.

Really works well, claleaned and made my piano keys look so much better.

El producto es increíble, cumple con la función de limpieza segura, mantiene el brillo del teclado y no deja ninguna textura porque es de rápido secado, yo lo uso en un Arturia Keylab Essentials
