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.

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.

Works. Very well

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.

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.

This product surprisingly leaves an undesirable film on my piano keys. I was not expecting that and used it only once. I've gone back to using a clean rag barely spritzed with water with a little vinegar.

This cleaned my ivory keys beautifully. But the packing job was pretty flimsy and the spray bottle apparatus broken; to use the cleaner, you must pour some of the liquid into a cloth. I 'm too busy to return it....but the next time they ship USPS, they need to put more bubble wrap around the nozzle. Otherwise everything is perfect. ann p

Used it seamlessly on ivorite and polyester finish.

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
