Keep your locks in tip-top shape with 3-IN-ONE® Lock Dry Lube, formulated to keep lock mechanisms running smoothly and prevent lock rust and corrosion. Our lock lubricant dries quickly and leaves no oily residue, which prevents dirt and dust from collecting in your locks.
Graphite powder is the preferred lubricant for locks. You should be able to get it at any hardware store in a squeeze bottle that is half air, allowing you to blow it right into the keyway. You are going to have to wait a while before putting it on, as the residual WD-40 will gum it up.
Graphite-free, 3-IN-ONE Lock Dry Lube is ideal for automotive, marine, home, and commercial locks and padlocks, and is safe to use on metal, wood, and most plastic surfaces (except clear polycarbonate and polystyrene).
3in1 oil is an extremely good product. Essentially it was used to lube machine parts (sewing machines, typewriters, clocks, etc.). It was also used as a penetrating oil untill the advent of liquid wrench, WD-40, and others.
3-IN-ONE oil can be used to lubricate tools, hinges, nuts and bolts, bicycles, wheels, fans and many other moving parts.
This silicone oil is safe to use on multiple surfaces, including plastic, metal, and rubber.
WD-40 and 3-In-One Oil work well for drilling bits because they are low-viscosity and high-quality oils that reduce friction between the drill bit and the surface it is going into. Both have a long history of success, so there really isn't anything negative to say about them in terms of performance.
Penetrants, like Kroil, are flammable and should never be used around an open flame. Similarly, do not apply heat immediately after an item has been sprayed with Kroil or any other chemical.
Oil might assist the moving parts of the motor in your car, but it is never a good idea to squirt it in a stiff lock. The oil will just combine with any grime already in the mechanism and compound the situation. Remove dust. If you have access to an air compressor – blow pressurised air through the lock to remove dust.
Penetrating Oil (WD-40)
One of the most common uses for penetrating oil like WD-40 is lubricating light-duty parts, such as the hinges and locks on car doors. These parts do not encounter harsh operating conditions like the engine or transmission.
To my eye (and nose!), it's not as clean and light as the Wahl Hair Clipper Oil, which is why I prefer that product. But 3-in-One is easy to find almost anywhere. In addition to lubrication it will penetrate rust, clean and protect tools, and just do the job.
Should I use WD40 to lubricate door locks? The simple answer is you should not use WD40 to lubricate locks. WD-40 is one of the solvent-based lubricants and does not contain any lubricant and over time can make your lock even stickier by gumming the lock up.
Common Causes of Sticky Door Locks
If a door lock is rusted or corroded, it can become hard to get the key into the lock, difficult to turn full, and also sticky and difficult to get out of the lock. If your lock is worn out, lubricant may be a temporary fix, but it's not going to resolve the problem.
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.
When you have bolts, nuts, threads, or other small parts stuck or rusted together, free them up quickly with 3-IN-ONE Fast-Acting Penetrant. This penetrating oil quickly breaks apart tough bonds, and is better than the competition in preventing new rust from forming.
3-IN-ONE ® Professional Grade Pneumatic Tool Oil
By removing calcium build-up while minimising rust formation, the 3-IN-ONE Professional Grade Pneumatic Tool Oil helps improve tool performance, so you tackle the project at hand with confidence.
And you must know where to place the oil (and where not to!). Don't use 3-in-One or even worse, WD40.
What Is the Best Lubricant for Door Hinges? The best lubricant for squeaky door hinges would be either a silicone spray or lithium grease. Silicon spray is cheaper, easier to apply and potentially less messy than lithium grease, which makes it the winner for us.
The oil may be called 3-in-1 oil or sewing machine oil. With a small rag or paper towel handy, place few drops of oil atop the tight horizontal pin joint at the hinge. The oil will be drawn into the joints, and you can catch any excessive oil with the rag by wiping the hinge. Repeat on all hinges.
3-IN-ONE is a specially formulated lubricating, penetrating, and cleaning oil.
3-IN-ONE is famous for how long it's been around… it's been solving problems & making people smile since 1884. And that's why the WD-40 Company officially acquired the 3-IN-ONE Oil business in 1995 and has been innovating ever since to produce the best product with the best delivery systems around.
A white lubricant, lithium grease is considered an all-purpose lubrication solution. It can be used to lubricate in applications involving metal-on-metal, or even metal-on-plastic. It effectively helps reduce unwanted friction and encourages components to move far more smoothly.
