Key-Brite Piano Key Cleaner 4 oz by Cory, Distributed by A Fully Authorized Cory Products Dealer

.

it works nicely.

These products are awesome at getting the finger prints off my shiny black piano. It makes my piano look so beautiful.

This was pretty good at cleaning the keys. Do not use this on the black keys as it will take some of the color off.

If your piano keys have gotten grimy, this is a good polish. Mine are pretty clean (I play with clean hands but if you have kids, they don't.) So this clear spray will take off that dark grime and make the keys feel and play better. I used to use Yamaha's key cleaner which was a white cream but this is a lighter, clear spray and easier to use. The keys felt good after I cleaned them, no residue or greasiness.

It doesn't help stains or discretion but leaves a residue

My new piano tech recommended this product and it was amazing. My keys look the best they've looked in the 30 years I've owned the piano. Easy to use.

I don't know why I gave it a three-star because it did not work. But maybe it didn't work for my piano because it was older or something I don't know but it may work for someone else.

dans le descriptif il était noté kit avec chiffon polisseur et je n ai reçu que le flacon de plus à l 'utilisation pas très efficace je ne sais pas en quoi il y a brillance

Nice and non sticky cleans the keys lovely.

Used it seamlessly on ivorite and polyester finish.

Made my Moog shine
