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.

Why did you pick this product vs others?: Nice product , gave my dusty keyboard a new look with shine , I love it

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.

Easy and keeps my keyboard keys clean

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.

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

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.

Works well on fingerprints

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.
