CorySuper High Gloss Piano Polish 8 Ounce Bottle for Pianos With High Gloss Finishes

I have used this product on all my high finish pianos. It's worth the money and last a long time. Takes of streaks and finger prints like a charm and it does repel dust.I used a mixture of alcohol water and windex before and the piano store told be their formula - it's what they use to polish all their pianos. It was difficult to get the shine I wanted.

seems to work well but my Kawai piano already has quite a nice finish. I just wanted to maintain & protect it. This product goes on quickly, polishes quickly. I always wondered why Carnauba couldn't work ??? But this stuff seems to work well

Have used for almost 30 years on my Hamburg Steinway grand with a high gloss polyester finish. Although I have a lot of micro-fiber cloths, for light dusting I prefer old, well-laundered cotton cloths. If there are finger prints, such as from the piano tech, then I use the micro-fiber with the Cory spray. Always flip to a new side or section of the cloth with each pass in the same direction, never circular or you will get swirl patterns building up over the years. If that happens get a bottle of Maguire "Swirl Remover", which surprisingly will also clean off any slight "dullness" that you did not realize had appeared. You won't notice the mirror-like improvement until after you have used it, a bonus after-effect. However, I had used the Maguire just about once every 5-10 years versus once every few weeks with the Cory product.The Cory bottle I first purchased lasted at least 10-15 years. It is the best thing I know of to reduce fingerprints from opening and closing the lid and fall board, plus reducing the accumulation of dust on a black piano. Definitely avoid feather dusters, as they will slowly scratch the surface from pushing the dust around.

Great product and customer service. We have a dining table with epoxy finish and this is wonderful to clean and condition it.

I have expensive stereo/AV speakers with piano gloss finishes. This product provides a high gloss shine, after I feather dust the components. I usually spray onto the cabinets, then wipe with microfiber cloth. Protects, but tough to spray as bottle contents get low. Also a little pricey. No complaints, have made multiple purchases.

Wow! This stuff is simple THE BEST! I tried three other polishes for our glass black Kawai baby grand piano. All of them were terrible and left the finish dull, kind of gummy, etc. THIS POLISH FULLY RESTORED THE PIANO TO LIKE-NEW! I just about cried with joy! I now use this as guitar polish for my 10 electric guitars as well. Fantastic! Get it!!

My seven foot high gloss black grand piano was starting to look pretty grimy. Purchased in 1996, I don't know that it ever had a real cleaning. Various cleaning services over the years had rubbed clothes over it leaving layers of stuff. It also had a lot of fingerprints and hand prints from moving. They never showed up too much on the black surface until it arrived in its newest location. With a bright window behind it, every smudge jumps out when you walk into the room. I tried a couple of "cleaners" that claimed to work safely on any surface, and they just left more stuff and new streaks. So I searched the internet for advice, and was ready to try Windex on the recommendation of one poster who seemed to know his chemistry. However, I saw this one mentioned and decided my expensive piano was worth a $17 gamble before I ruined it with something else.This product is especially formulated for a black piano, and is everything it claims to be. It removed all the old gunk left by well intentioned house cleaning services. It removed all the fingerprints. It left my piano looking like a black mirror. Some areas took a few sessions to get clean. I used this product together with an old white cotton T shirt. I sprayed the product on the surface with the piano closed as recommended. They warn you not to spray if it might get on the strings or keys.Today, playing my piano I noticed that some of the worst spots were with the piano open. The fingerprints looked as though the last movers rebuilt an engine before moving my piano. Perhaps it is just the spot where I always put my hands when lifting the very heavy lid. Over 17 years, some serious paw prints developed:) So I sprayed the product onto the cloth so as not to get it on the strings or keys. It worked like a charm. The worst of the grime came off quickly, as long as I used enough of the product. I'm very happy to share my experience with other piano lovers. Trust me, your piano is worth a $17 bottle of cleaner and a used T shirt. (Looks like the price went up a little since I bought it, but it's still worth it.) If the manufacturer were here with me, I would buy him an expensive dinner in appreciation.

This stuff is great! It really does a good job. It even made a nasty looking scratch disappear.
