No, regular WD-40 Multi-Use Product is not recommended for locks. While it can temporarily free up a sticky lock by flushing out gunk, it acts as a penetrating solvent rather than a lasting lubricant. Over time, it leaves behind a sticky residue that attracts dust, dirt, and moisture, which will eventually make the lock jam again.
WD40 strips a lock of its natural lubricant and can make your lock stiffer or even sticky. Likewise, it can attract dust and dirt into your locking mechanism and lock which will affect how your lock works. Top Locksmith Tip: Use a lock lubricant instead of WD40 to help with stiff or sticky door locks.
No, WD-40 is not good for arthritis. It is a harsh industrial lubricant and penetrating oil, not a medical treatment.
The ideal way to fix a seized lock is to use a lubricant. WD-40 offers several solutions to maintain your locks: WD-40 Multifunctional Product, WD-40 Specialist Locks Lubricant or WD-40 Specialist PTFE Dry Lubricant. Each of them has its advantages and can therefore meet your lock maintenance needs.
When it comes to locks, never use the original blue-and-yellow WD-40 Multi-Use Product. It is a penetrating oil and solvent, not a lubricant. It will initially free a stuck lock but will eventually strip existing grease, gunk up the mechanism, and attract dust and dirt.
Polytetrafluoroethylene, or PTFE, is a Teflon-based lubricant that dries inside the lock to leave behind a non-stick, water-repellent film on all the surfaces. Since it's dry, it doesn't attract dust or dirt.
While WD-40 is a great multipurpose solvent, it is a poor long-term lubricant and should never be used on items that require specialized lubricants, come into contact with food, or are made of sensitive plastics and rubber.
The best overall lubricant for locks is a professional-grade dry lubricant like a PTFE spray (e.g., Houdini Lock Lube or Tri-Flow). Unlike standard oils or greases, these dry lubrics leave a frictionless coating that won't trap dirt, dust, or metal shavings, keeping your mechanisms smooth and corrosion-free.
Using WD-40 with the straw attached to the nozzle, spray several large doses into the lock and leave for an hour. Try inserting the key again. If the key does not enter repeat this process as we mentioned before it can take days for the WD-40 to penetrate and release the lock.
Hyaluronan, the key ingredient in Gel-One, is a natural substance found in the fluid within your joints. The body's own hyaluronan acts like a lubricant and shock absorber in the knee joint and is needed for the joint to work properly.
There is no single "best" painkiller for arthritis, as the ideal medication depends on the type of arthritis, the severity of your symptoms, and your overall health. The most common options include:
WD-40’s secret to success is its unique formulation: it is roughly 50% petroleum solvents, 25% paraffinic base oils, and specialized additives. This mix gives it a multi-purpose edge:
To unstick a stubborn door lock, insert the WD-40 straw into the keyhole and give it a short spray. Insert and remove your key several times, wiggling it gently to work the spray into the pins. Wipe excess fluid from the key and the door.
Some of the top door lock lubricant options are:
To loosen a stiff lock, apply a dry lubricant like powdered graphite or a specialized PTFE spray into the keyhole and work the key in and out to distribute it. Avoid oil-based lubricants like standard WD-40, as they attract dirt and can worsen sticking over time.
Original WD-40 is a penetrating oil, not a long-term lubricant. While it can temporarily free up a stiff lock by flushing out gunk, it eventually evaporates and leaves a sticky residue that attracts dust, making the problem worse. For lasting results, use a specialized lock lubricant instead.
There are a few different effective methods to remove rust from metal. You can either remove rust passively by letting it soak in an acid (like vinegar, citric acid, or lemon), or remove it actively by scrubbing it away with abrasive materials (like baking soda and steel wool).
Open a stuck lock by lubricating the mechanism with graphite or silicone spray, jiggling the key gently, or using a stiff plastic card to retract the spring latch. If it is a door, lift the handle while pushing or remove the hinge pins to bypass the lock.
Yes, you can use Vaseline instead of WD-40 if you need a quick substitute. However, keep in mind Vaseline may not work for all applications, including inside locks. While it can work great on door hinges, it may be too sticky for locks and end up attracting dust and dirt particles—which can cause damage to your lock.
Teflon Dry Lubricant
Teflon-based dry lubricant is preferred by some locksmiths over other options. It's a great option because, as well as lubricating your lock, it repels water and dust. Meaning that once you fix a lock with this type of lubricant, you can expect the lock to be in good shape for a long time.
To fix a door lock that is hard to turn, apply a dry, lock-specific lubricant (like graphite powder or PTFE spray) into the keyway and work your key in and out. If lubrication fails, the issue is likely door misalignment; tighten loose hinge screws or adjust the strike plate.
You should never use standard WD-40 in locks because it is a penetrating oil and solvent, not a lubricant. While it will temporarily free a sticky lock, it leaves behind a sticky residue that hardens into a gummy varnish. Over time, this traps dust, dirt, and pocket lint, permanently ruining the lock's inner mechanisms.
Spraying WD-40 in your toilet bowl dissolves stubborn hard water stains, rust, and lime deposits. Its petroleum-based formula breaks down grime and leaves behind a slick, water-repellent coating that prevents new mineral buildup and waste from sticking to the porcelain.
There is no functional or safety reason to keep WD-40 in a refrigerator. In fact, it is better stored at room temperature. However, you might hear about this because WD-40 is an excellent product for your fridge.
