100% Pure PTFE Dry Lubricant Powder in 2.5oz, Ultra Fine Powder with 1.5 Micron

The media could not be loaded.  My original purpose for this product was to lubricate pieces called "knuckles" in piano actions.Knuckles look something like a human knuckle and are a little felt pad covered with a very fine grade of suede. A tiny piece of wood called the "jack" knocks and rubs against the knuckle directly transferring all of the force and energy of the keypress to the hammer.Amazingly this incredibly complex mechanism filled with many moving parts for each and every key is only lubricated in one place--and it is technically "permanent."The ends and one side of the jacks are lubricated with graphite--pencil "lead" essentially--by burnishing it onto the wood in a rather painstaking process. While impervious and nearly permanent it can be "touched up."Traditionally the knuckles received no lubrication because there was no lubrication to use. That was then. This is now. Now we have this stuff. It says "WAX" on the bottle but when you read a little further down it gives you the chemical abbreviation PFTE (the common trade name is "Teflon") but in powder form. This is a fine (as in small) grade approximately 1.5 microns in average size.I am not a piano "professional" but was working to clean the action of my piano. Information is somewhat difficult to find about anything to do with this but I found that some used this type of product for this purpose so I ordered some.I applied it with an ordinary quality artist's sable brush to clean--thoroughly clean--knuckles. Cleaned with softish bristle brush, canned air, soft brass brush and insanely soft brass (fine garment) brush. Methyl-ethyl-ketone (if you can get it in your area still) to clean the brass brushes too. Apply all the way around the knuckle! You must work from both sides and it takes considerable time.Do consider getting a COVID face mask out when using this stuff. It's not filled with warnings but thee is the little red triangle with "inhalation alert" written next to it. When you use you'll understand why. You may think you began, are, or in my case resumed smoking. Things this small are not particularly good to inhale even if they're not inherently harmful. And I'm sure you don't want to eat the stuff even if there's no "poison" alerts or anything like that on the packaging.The video has a purpose. It features two of the very same songs played on the very same piano for a review of automotive wax I used when restoring the case:https://www.amazon.com/Mothers-05550-California-Brazilian-Carnauba/dp/B0002U2V1O/ref=sr_1_3?crid=27AL5K27Y9HAG&keywords=mother%27s+pure+carnauba+wax&qid=1688497177&sprefix=mother%27s+pure+carnauba+wax%2Caps%2C131&sr=8-3While the action received a thorough cleaning and I did touch up the graphite burnish on the jacks and make use of a carefully masked spray lubricant also containing PTFE power (not available Amazon) I believe a significant amount of the improved delicacy of the performance is due to this "wax." The hammers have also been improved somewhat but that's another review perhaps.I'm also using it to lubricate so-called "tipper drawers" in quality (if older) solid wood furniture as well as the remaining contractor-built cabinetry with their still excellent if never "silky" drawers. While I've kept those cabinet drawers waxed with paraffin over the years this "wax" that I applied to a couple of the heaviest a couple weeks ago now has noticeably improved the smoothness of 50 year-old drawers used almost daily.While I couldn't get it into good focus (or trick the camera) the product is visible and highlighted in the upper-right corner of the video :)

Exactly what I needed as an additive for hot waxing my MTB chain. I chose this one because it is a very fine 1.5 micron powder, and others on Amazon are 2-3 micron or larger. The only reason I am giving it 4 stars instead of 5 is because it is significantly more expensive than other PTFE powders. Worth it I guess, but more expensive than it needs to be.

I combine this 1 part to 10 parts paraffin, heat it , and use it to coat my bicycle chain. The Teflon and paraffin are white so you never end up with black grease on your hands, handlebars, and clothing. Seems to have my bike riding very smoothly and quietly.

I add this to melted paraffin wax as a bicycle chain lubricant and it works very well.
