For door hinge oil, your best option is to use silicone spray or white lithium grease. Silicone is the easiest, but it does not last as long as the grease. When used properly, the mess is minimal.
White Lithium Grease
This product has been specifically designed to work on metal parts, making it ideal for door locks, latches and hinges. It's also long-lasting and will hold up under harsh conditions like rain and snow.
White lithium grease is good for metal-to- metal joints like hinge and latch mechanisms, which need a clinging grease to repel water and hold up under harsh conditions. WD-40 is for light-duty lubrication and freeing up sticking or partially rusted hinges and a car door latch.
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. If you don't have either silicon spray or lithium grease don't panic.
Silicone Spray
A popular choice that many choose to stop doors making a squeaking sound is to spray the hinge with some silicone. Available at most good hardware stores, it's free from grease and oil and is safe to use on wood, metal, plastic, and rubber.
It acts according to Newton's third law of motion. In order to perform a motion, the force applied to start the motion must be greater than the frictional force. Hence, upon applying oil on door hinges, the friction decreases.
For door hinge oil, your best option is to use silicone spray or white lithium grease. Silicone is the easiest, but it does not last as long as the grease. When used properly, the mess is minimal. Remove the hinge pins from the hinge one at a time.
There are other dry lubricants, Teflon or Polytetrafluoroethylene (PTFE), being the primary alternative to Moly and Graphite. PTFE lubricants have many great applications where being inert and non-conductive are desired characteristics.
Silicone spray is lighter than lithium grease. It's a great lubricant for car door hinges, and it can help stave off rust. It lubricates metal as well as materials such as plastic and nylon. WD-40 Specialist is a popular silicone spray.
LITHIUM GREASE
It is designed to provide long-lasting protection against oxidation, corrosion, extreme temperatures, and wear and tear. Lithium and lithium complex greases are also characterised by their excellent lubrication, good water resistance, and the ability to withstand high pressure and shock loads.
There are a number of cooking oils that can be used, such as coconut, canola and olive oil, to lubricate hinges. If your door swings relatively easily but still has a tendency to squeak, these methods are effective for curing squeaking. Even though cooking oils can work, they are magnets for grime and dust.
If we apply oil to the door hinges, the friction will decrease because lubrication always decreases friction between two surfaces; hence, applying oil will decrease the friction.
It's caused by the rubbing together of the hinge parts. Microscopic pieces of the metallic coating plus dirt and lubricating oil combine to produce that nasty residue that eventually falls to the floor.
Regular maintenance of door hinges will not only keep them functioning properly but also increase the lifespan of your doors. In general, you should lubricate your door hinges about every six months, or sooner, if the door gets a lot of use or starts squeaking.
Lithium grease offers longevity due to its durable nature. This means that the lubricant will last for extended periods of time. This not only reduces the maintenance time, but makes repeated application unnecessary, leading to cost savings. Lithium grease also has a thicker viscosity.
Petroleum jelly – Remove the pin from your hinge and cover it in petroleum jelly before reinserting. Paraffin candles – Remove the pin from your hinges and rub hot wax onto it before reinserting. Olive oil – Use a cotton swab to apply a little bit on top of your hinges.
If the doors on your car creak and groan when they're opened or closed, the hinges are dry and need lubrication. That's not just so they no longer disturb the peace. Without lubrication, hinges can eventually bind and bend, and the doors might twist off center and even stick.
Grease your hinges with vegetable oil.
If you have a squeaky door or doors, or really if you have doors with hinges that could potentially become annoyingly squeaky in the future, you should grease the hinges with vegetable oil. Add a dab or two of oil to a clean cloth and rub the oiled cloth along the hinge.
