Can I Use Wd40 On My Sewing Machine

General Information

WD40 is an all-in-one lubricant, penetrant, cleaner, and corrosion inhibitor that is widely used in the maintenance and repair of a variety of items, including machines. WD-40 is a popular choice for general household and car maintenance and has been in the market for decades.
WD-40 can be used on all types of equipment that experiences friction, such as hinges, latches, and locks, but there are a few areas that it should not be used. The same goes for sewing machines. While WD-40 can be used to treat certain parts of a sewing machine, it is not recommended for use on the internal mechanisms of a machine, as it may damage delicate components or cause the machine to malfunction.

Raw Materials

WD-40 consists of mineral oil, lubricating fluids, and various other compounds. It is designed to penetrate deeply into metal surfaces, displace old lubricants, and loosen rust and corrosion. WD-40 is designed to penetrate metal surfaces and loosen the rust, dirt, and grease binding metal parts together. It can also act as a lubricant, reducing the amount of friction between two metal surfaces.
One of the main components of WD-40 is a blend of petroleum-based oils. These petroleum-based oils are designed to mix with existing oils and penetrate into small crevices and cracks in metal surfaces, as well as break down rust, dirt, and grease. Other components of WD-40 include antifreeze agents, corrosion inhibitors, and other additives.

Sewing Machine Parts

Sewing machines contain both metal and plastic parts. Plastic parts of a sewing machine can be safely treated with WD-40, as it is designed to penetrate metal surfaces, not plastic. WD-40 can be used to clean and lubricate plastic parts such as the tension dial, hook, and the presser foot.
WD-40 should not be used on metal parts of the machine, such as the hook shaft, hook race, and bobbin winder. WD-40 may break down the oil and grease used to lubricate these parts, causing them to wear down faster and eventually break.


Instead of using WD-40 as a lubricant for sewing machines, a machine-specific oil should be used. Machine-specific oils are designed for sewing machines and have a higher viscosity, which make them better at lubricating the internal parts of a machine. They are also more resistant to water and won’t break down as quickly as WD-40.
In addition to oil-based lubricants, most modern sewing machines come with grease-based lubricants. Grease is superior to oil as it is designed to remain on the surface of the metal longer, providing better lubrication and protection.


Before treating a sewing machine with WD-40 or any other lubricant, it should be thoroughly cleaned and inspected. Dirty or faulty parts should be replaced first, as using WD-40 on these parts might make the problem worse.
It is also important to make sure that the area is well ventilated as WD-40 is combustible and may release toxic fumes. WD-40 should never be used on a hot sewing machine as it may cause a fire.

Storage and Disposal

WD-40 should be stored in a cool, dry place and away from sources of heat or ignition. When disposing of WD-40, the user should consult the local hazardous waste management authority for the appropriate method of disposal.

Efficiency and Cost

WD-40 is generally a cost-effective solution for preventing rust and providing lubrication for items in general. It is also easy to find and store and is suitable for almost any type of job, including sewing machines.
However, WD-40 should not be used on all parts of a sewing machine, as it may break down existing oils or cause the machine to malfunction. In addition, it is not as durable or efficient as machine-specific oils and grease, which are designed specifically for sewing machines.


In conclusion, WD-40 is a popular product for all-around maintenance and repair. While it can be used on all types of equipment, including sewing machines, it is not recommended for use on the internal mechanisms of a machine as it may damage delicate components or cause the machine to malfunction.
When used in accordance with manufacturer’s instructions and proper safety measures, WD-40 can be an effective and cost-effective solution for removing rust and providing lubrication, but it should not be used in place of machine-specific oils and grease.
