Box is damaged when arrived. Package seems to be in a small plastic shipping bag. But overall it works as it should.

I’m here because I’m using it to clean the lead screws on my Bambu X1C printers. I purchased the 3 pack for around $17 which after this post I believe that was a steal. Works great! Better than anything else on the market. Sales I’m sure blew up due to the viral video. The ease of using this product is mind blow something that was marketed for bikes is now going to change with the growing community of 3D printing.

I can just imagine a shoe lace manufacturer looking at a bad lot of shoe laces. “They’re too short and loose, no-one will buy these. What are we going to do?” (for some reason they have an Italian accent in my head).
“I know, we’ll sell them to cyclists to clean their cassettes”
“You’re a genius, Giuseppe, that’sa what we’ll do”
So that’s what they did and this is the best way to clean a cassette without removing it. Seriously, I know they were carefully designed for their purpose.
You could probably clean them and reuse them but I’m not sure it’s worth it. One of them can clean a cassette especially as I have a bucket of hot soapy water with me because I’m cleaning my bike. Get it wet and soapy and the grime comes right off. Rinse it every few sprockets.
One other nice thing is that, unlike a brush, they don’t spray greasy water all over the place. You can use them indoors without fouling the floor and walls and other parts of the bike. I totally recommend them.

This product has made the cleaning of my 3D Printer Z Rods much easier and more thorogh. It gets right into the smallest of threads and cleans out all debris and grease. I probably wouldn’t try to clean them but the box says it should be possible.

Ho sempre pulito i pignoni smontando interamente la cassetta, ma senza esagerare, con questi “fili” si fa un ottimo lavoro, migliore di quello che si fa normalmente con gli stracci.
Sembrano usa e getta ma in realtà sono in microfibra lavabile.

This Finish Line Gear Floss has become my go-to tool for cleaning those hard-to-reach places. I originally bought it for my 3D printer, and it does an absolutely amazing job of removing any dust or debris that accumulates on the Z-rods. I just wrap the floss around the rod and slide it up and down a few times, and it comes out perfectly clean. This helps keep my printer running smoothly and prevents any issues caused by dust buildup.
But I’ve since discovered that this floss is incredibly versatile. It’s great for cleaning all sorts of things with intricate parts or tight spaces. I’ve used it on electronics, small appliances, and even jewelry, and it’s worked wonders.
The microfiber floss grabs onto the dirt and pulls it out way better than brushes or rags ever could. It’s surprisingly strong and doesn’t tear easily, even when you’re really working it into those tight spaces. And the best part is, it’s washable, so you can use it over and over again.
If you’re looking for a simple but effective way to clean those tricky spots that are usually a pain to reach, this Finish Line Gear Floss is a must-have. It’s a brilliant little tool that I highly recommend.

Convenient, inexpensive assist for cleaning bicycle cassette (gears).
This is for cleaning grit between gears and on gear faces. This is not for very heavy dirt, as a mountain bike in mud may get, where you’d likely want to first do a preliminary wash down.
Using it dry I did not have a good time as it tended to stick too easily.
I spray some WD40 onto the floss and find it helps clean better, picks up better, and also allows it to slid in between the gears better.
When cassette stationary, I’ll slide the floss repeatedly back and forth to clean areas of the gears.
With the slight pulling motion, I can get the cassette to ‘roll’ or index on certain pulls, so that your cleaning various areas around the full 360 degree rotation.
A single floss will clean the full cassette – provided that you consistently clean between rides and prewash heavy dirt first.
I also carry one in my bag on rides, in the event I need to clean ‘on the go’.
Happy with this product

Save a video of these online where someone was using them to clean the lead screws on their bambu lab 3d printers. Works perfectly. Makes cleaning super fast and easy.

Not exactly the intended use case, but these clean threaded like a champ. Use these to remove the lube from my 3D printer rods quickly. A quick wash and they are good as new.

Diese Reinigungschnüre sind genau das, was ich gesucht habe! Ich benutze sie, um die Z-Spindeln meines BambuLab sauber zu halten, und bin absolut begeistert. Die Reinigung geht super einfach und vor allem schnell – in wenigen Minuten ist alles erledigt. Ein weiterer großer Pluspunkt: Die Schnüre lassen sich problemlos waschen und mehrfach wiederverwenden, was sie sehr nachhaltig macht. Absolute Empfehlung für alle, die ihr Gerät pflegen wollen!
