Over time, airborne dust, dirt, and chemicals can settle on and in locks and create friction inside the precision locking and keying components, thus interfering with the function. Locks must be maintained to keep them functioning properly and lengthen the product life. This is the ideal lubricant formulated specifically for locks. What is PTFE? PTFE is the acronym for Polytetrafluoroethylene, which is the most slippery material known to science today. All surfaces have microscopic irregularities, which create friction when rubbed against each other. The introduction of PTFE into these irregularities smoothes out the surfaces, reducing the wear and sticking that friction causes. The most familiar name of PTFE is Teflon, which is the registered trademark for DuPont’s non-stick cookware. Where can the new lock lubricant be used? Everywhere. This formulation is ideal for padlocks, door locks, automotive, marine, and multipurpose applications. The 2300D pen oiler is convenient for consumers and can easily be applied to keyways or shackle holes. ## Features - Keep your locks operating like new in any environment andndash; snow, rain, freezing temperatures, marine, extreme heat - Ideal for padlocks, key locks, combination locks, door hardware, automotive, marine, and multipurpose applications - Prolong the life of your lock; Apply 2-3 drops in key hole and shackle openings every three to six months for trouble free operation - Provides a long lasting protective shield against dust, dirt, salt, and moisture to prevent rust, corrosion, and loosens stuck parts - Wide temperature range of -40F to 500F; Lock lubricant is non-toxic and biodegradable ## Technical Specifications | Specification | Value | |---------------|-------| | Material | Ptfe | | Brand | Master Lock | | Package Information | Syringe | | Liquid Volume | 0.25 Fluid Ounces | | Item Weight | 0.02 Kilograms | | Recommended Uses For Product | Door,Indoor,Outdoor | | Viscosity | Low viscosity, stable across wide temperature range | | Upper Temperature Rating | 5E+2 Degrees Fahrenheit | | Flash Point | 500 Degrees Fahrenheit | | Item Form | Liquid | | Global Trade Identification Number | 00071649154225 | | Manufacturer | Master Lock | | UPC | 071649154225 | | Number of Items | 1 | | Part Number | 2300D | | Item Weight | 0.704 ounces | | Product Dimensions | 0.39 x 0.39 x 0.39 inches | | Item model number | 2300D | | Is Discontinued By Manufacturer | No | | Size | 0.25 Ounces | | Color | Red | | Item Package Quantity | 1 | | Number Of Pieces | 1 | | Included Components | Lock Lubricant | | Batteries Included? | No | | Batteries Required? | No | | Warranty Description | Limited Warranty | ## Product Details - **Material:** Ptfe - **Brand:** Master Lock - **Package Information:** Syringe - **Liquid Volume:** 0.25 Fluid Ounces - **Item Weight:** 0.02 Kilograms ## Images ![Master Lock PTFE Lock Lubricant, Non-Toxic and Biodegradable Lock Lubricant, 0.25 Fluid Ounces, 2300D - Image 1](https://m.media-amazon.com/images/I/41-Pdqsui7L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: If using this for a car key to get the ignition to work better without sticking; should you apply this directly on the car key or inside the ignition?** A: The formula within this lubricant was designed to be best used with padlocks, cylinders and mechanisms within the lock. **Q: Is this product good for use with a combination padlock (lock without a key.)** A: Pamela I don't really know. I've only used it on my key locks and works fine with them. If you put a few drops in the shackle opening it should work ok. **Q: Would this be suitable for micrometers and other delicate measuring instruments?** A: Yes it should work fine on your micrometers and calipers, especially if they are kept climate controlled. **Q: Silicone based? I didn’t see where it says, only biodegradable?** A: PTFE formula, whatever that translates to. Good stuff. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Specially Made for Locks, Here to Buy Tube #2 After Four Years *by B***T on August 25, 2019* Well.I bought my little tube in 2015 (yes, almost 4 years ago), and I've been using this occasionally over the years, more as a preventative measure than anything else.Yesterday's events have encouraged me, however, to write a positive review for it.A Master lock on my property has been locked outside in the South Florida elements for at least several years, and during that time, not only did it go through Hurricane Irma, but it never got used (i.e. unlocked).Yesterday I needed to finally unlock it, and just as I feared, it was rusted shut. Although the key went in, it wouldn't turn a bit. I didn't want to wait, and I really didn't want to shell out $$$ and buy a bolt cutter, so I did some research, and went back there again with this little tube and a hammer. Greased up the holes, waited, banged the lock, jiggled key in lock. Repeated several times, and voila! it worked. The lock still isn't working buttery smooth, but who cares, I got it off.Don't know what's in this lubricant exactly, but it sure loosened up the rusty insides of my Master Lock, giving me access and saving me $.The lubricant i have is actually so old now that it's not even that runny, and the label is cracking too, but it still worked like a charm, and really proved itself too. :-DSo,I'm here to buy another tube after yesterday's events, and although $5 for this little thing sounds expensive, for me that has worked out to be $1.25 a year on 3-4 padlocks, for saving me a lot of backyard sweating and cussing (which I do enough anyway), and emergency trips to the local home improvement store, so it's worth it!Also, I don't know if regular corn oil would have worked just as well, but this lubricant specially made for locks claims it has "PTFE" so I dont want to use regular cooking oil or WD-40 and ruin perfectly good locks or make a bad situation worse.That's a picture of my old lubricant, the lock which came off with its help, and the q-tips I'm using to clean out its insides, showing all the rust.Recommend. ### ⭐⭐⭐⭐⭐ Useful! Easy. Tiny, but how much do you need? *by J***K on December 9, 2021* It is a tiny squeeze container shaped like a pen. One lock may use 10% of the lubricant. If you use it once or twice a year on a couple of locks/doors, then it may last you 3-5 years. It is for light use.That said - application is so easy. Could not be better. The applicator tip fits easily in the lock. Squeezing out a couple of drops is a piece of cake. The stiff/frozen/problematic lock now works like new. Perfect for front door locks in cold/dry climates. It even packs up well, a black plastic tip and a clear top case. No spilling. Safe to store.Great to have one around home or office. Prefect for tool box (next to plumbers tape) or kitchen junk drawer (by a multiuse screw driver).Note: We were not compensated in any way for this unbiased review. No one should be. ### ⭐⭐⭐⭐ Worked Great *by B***N on April 4, 2022* I noticed a gate padlock I put on a year ago was getting a little rusty, so after some research, and watching their video on how to use it on YouTube, I did as instructed. You basically apply a few drops at both ends (key end and hasp end) and then turn the key, work the hasp in and out, and spin the hasp around a bit, and the lock is well lubricated.What I absolutely didn't like about this was the plastic tube it comes in. It's meant to be like a pen with a pen-type clip, with a plastic tube body and cap. The problem was it wasn't easy to open or even to tell how to open it until I slide the clip and started squeezing and pulling. I was ready to just cut it open when it finally gave, but it wasn't intuitive. That could be improved, but the product worked great. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/6447065-master-lock-ptfe-lock-lubricant-non-toxic-and-biodegradable-lock](https://www.desertcart.gr/products/6447065-master-lock-ptfe-lock-lubricant-non-toxic-and-biodegradable-lock) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-25*
