Protek 1406 Cleaner, Lube and Protectant, 4 oz Bottle

I had a couple of sticky piano keys, i.e., they would go down, but not return up. You can find info and videos on the Internet about how to fix this. It's a lot of work for a novice, but doable. This chemical is applied to a little pin deep in the key mechanism. Tiny amount does the trick.

This product worked soooo good! I now see why the piano repair websites recomend it. The action in my piano went from hammers sticking and slow to return to like new! I recomend getting a syringe with a needle, it lets you put a few drops right where you need. And 2 to 4 drops on each side of a hinge is all you will need.PS: I am doing this review 6 months after i used it and my piano still works incredible.

My electric piano keys started sticking after 10 years. I used this oil on the keys where they pivot and after a week of letting it soak in, the stuck keys started working.

Great for lubricating piano action parts. It also cleans as it lubricates the moving parts of the action. I would recommend this product.

Weeks great

Unlikely that this will reach anyone... but who knows? I play piano and harp. I saw my piano tech using this on the piano and got an idea. My harp strings had worn grooves in the bridge pins and started sticking. This created a problem for tuning. When I would turn the tuning wrench the tiniest bit to raise or lower the pitch *nothing* would happen... so I would turn a little more, and so on, until... PING! The pitch would either jump or fall too much because the strings were sticking in the grooves. Protek is the perfect solution because it is non-corrosive, non-reactive, and doesn't "travel." For harpists, that means it won't break down the nylon or the gut in your strings and won't slide down the strings and make them greasy and gross. It worked like a charm! What I did NOT expect was that (apparently) in freeing up the strings––releasing the strings from being stuck in the grooves––the sound improved immediately. All I did was touch a Q-tip dipped in Protek to the spot where the string meets the bridge pins. Instant results. If you're a harpist, buy the smallest container available. You'll never use it all, but absolutely worth having.

Lubrication for keys on a century old piano. Made it feel brand new.

I'm a long-time user of Protek CLP, and there is nothing on the market that compares with it. It's great for minor sticking problems in piano actions - especially on hammer knuckles. CLP does not stain wood, leather, or metal, and it does not harm the piano action in any way. At least once a year, I lube the entire action of my grand piano, and the immediate difference is apparent. I also use some on other moving parts such as damper rods to prevent squeaks and binding. I use a small "oiler" to apply it. Users should be aware that CLP does evaporate over time, so whether used or not, it will eventually "go away." Although it's a bit more expensive from Amazon, the other sources charged significantly for shipping. This made it a good buy from Amazon.
