Protek 1406 Cleaner, Lube and Protectant, 4 oz Bottle

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.

Great for Piano and gun lube!

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.

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

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.

Keys were sticking but my piano repairman used this product I purchased and now my piano functions perfectly.

Weeks great

I saw our piano tuner guy fix some stuck keys once with a liquid. I didn't want to depend on him, did a little research and found this. Now I can fix keys without having to call him. Rarely do I need it, but it's immediate and comparatively inexpensive. I also had a nice recliner that got to grunting and groaning just from siting in it and shifting weight. I figured it was wood on wood rubbing. Tried this stuff. Yay! No more squeaky chair.

Excellent center pin lubricant for acoustic pianos when used sparingly with a syringe.

Produit de haute qualité. J’ai lubrifier toutes les articulations en bois mécaniques de mon piano des années 50. Très bon résultat !!!!

I use this product all the time
