The Ultimate Guide to Sewing Machine Maintenance: Keep Your Machine Running Like New
A sewing machine is a powerful tool—whether you're creating custom garments, quilting, or mending clothes, it’s the heart of your sewing setup. But like any precision instrument, it needs regular maintenance to function properly. Neglecting it can lead to skipped stitches, thread jams, or even serious mechanical damage.

Why Regular Maintenance Matters
Routine sewing machine care prevents:
Mechanical failure from worn-out or dirty parts. Poor stitch quality caused by lint buildup or improper tension. Fabric damage from burrs, dull needles, or rough feed dogs. Costly repairs, which can often be avoided with preventive upkeep. A well-maintained machine not only runs better but also makes your sewing more enjoyable.

Step-by-Step Sewing Machine Maintenance Checklist
1. Always Start With the Manual
Each machine is slightly different. Your sewing machine’s manual will tell you:
Which parts to clean and oil.
How to remove covers safely.
What kind of oil or parts are compatible.
How to troubleshoot common problems.
If you lost your manual, most brands offer free downloads from their websites.
2. Unplug and Prepare Your Work Area
Before any maintenance:
Unplug your machine
Remove the needle, presser foot, bobbin, and thread
Lay down a soft towel or mat to protect your table and catch small screws or parts
Lighting is key—use a bright desk lamp to see dust and lint more clearly.
3. Deep Clean Lint and Debris
Dust and lint are your machine's worst enemies. Here’s how to clean it effectively:
Bobbin Area: Remove the needle plate and clean around the feed dogs and bobbin case using a lint brush, soft cloth, or vacuum with a small nozzle. Pipe cleaners are great for bending into small places and clinging to lint that can then be pulled out. Wipe the lint off of the pipe cleaner before inserting it again into the machine that way it will be available to pick up more lint each time it is inserted.
The area around the feed dogs will often become impacted with lint and should be cleaned often. Never use sharp metal objects such as a screwdriver or nail to dislodge packed lint. Bamboo skewers used for making shishkebabs are ideal for this purpose because they’re hard, but won’t cause burrs (small metal scrapes in the metal that create rough edges) in the metal. Don’t use toothpicks, since they may break off in the machine and be difficult to retrieve.
Tension Disks: With presser foot raised (which opens the disks), slide a piece of unwaxed dental floss or thick thread back and forth to remove lint
Thread Path and Take-Up Lever: Wipe gently with a dry cloth
Avoid: Compressed air—it can push debris deeper inside the machine.
4. Removing Burrs
Burrs are created by metal hitting metal. For instance, if you scrape or dig a machine part with a screwdriver or other metal implement, you’ll create a burr. Burrs are also created when the machine operator pulls the fabric from behind to help feed it through the machine, causing the needle to strike the throat plate. This action often results in a broken needle. Broken needles that fall into the shuttle area create burrs in the bobbin casing and race hook. If thread continues to break and runs develop in fine fabrics, check the machine parts for burrs. Run your hand lightly over suspected parts to feel for any rough edges. If burrs are found, they can usually be removed with a piece of crocus cloth. This is very fine sandpaper made from fabric impregnated with jeweler’s rouge. Never use regular sandpaper. Doing so may only add to the already damaged area.
5. Oil the Machine (Only Where Recommended)
Oiling reduces friction and prevents metal parts from seizing up. Only oil where your manual directs—some modern machines have self-lubricating bearings.
To oil:
Use only sewing machine oil (never general-purpose oils) Sewing-machine oil is thin and doesn’t congeal and become gooey over time, eventually stopping your machine.
A good way to determine which parts of the machine to oil is to put the machine on its widest zigzag and longest stitch and hand-turn the wheel forward. Any part that moves needs to be oiled. The machine should be oiled when the uptake is at its highest point to allow all of the internal workings to be in proper alignment to accept the oil.
Never oil the motor. If your machine isn’t self-lubricating, you’ll find a small oil port near the motor. Squeeze a few drops of oil into the port to oil the bearings. Unlike regular oils, machine oil evaporates over time. Parts like the race move twice as fast as other moving parts on your machine and should be oiled after six to eight hours of running time. If you hear a clatter inside the shuttle, you’ll know oil is needed.
Apply sparingly—a single drop goes a long way
After oiling, run the machine on scrap fabric to absorb excess oil
Frequency: For most home machines, every 10–20 hours of sewing. Industrial or vintage machines may need it more often.
6. Check and Replace Needles Frequently
Needles get dull or bent with use, leading to:
Snagged or skipped stitches
Fabric pulls or holes
Machine timing issues
When to change a needle:
After every major project
Every 6–10 hours of sewing
Emmediately if you hit a pin or hear a thud
Choose the right type and size for your project—universal, stretch, denim, or quilting needles all serve different purposes.

7. Check Thread and Bobbin Quality
Old, frayed, or cheap thread can cause lint build-up and tension issues. Make sure:
You’re using high-quality thread suited for your fabric
Bobbins are wound evenly and inserted correctly
Bobbin cases are free from burrs and scratches
Inspect the bobbin tension as well. If threads are bunching up, adjust as needed and test on scrap fabric.
8. Tension and Stitch Quality Check
Improper thread tension leads to uneven stitches and puckering. If your tension is off:
Rethread both top and bobbin thread completely
Clean the tension discs
Reset tension to the default setting and test
Always test new thread, fabric, and tension on scrap material before starting your actual projproject.
9. Inspect and Clean the Feed Dogs
The feed dogs move fabric through the machine. Over time, lint builds up in the grooves, and they can lose traction.
To maintain:
Remove the throat plate regularly and clean between the teeth
Check that the feed dogs are not worn down or jammed
Ensure they rise and lower smoothly when using features like darning or free-motion quilting
10. Keep It Covered
Dust can infiltrate a sewing machine even when it’s idle. Cover your machine with:
A dust cover or soft fabric case.
A hard cover if you travel or store it frequently.
Also avoid storing the machine in damp, humid areas to prevent rust and corrosion.
11. Schedule Professional Servicing
Even with regular maintenance, a sewing machine needs professional servicing every 12–18 months, especially if:
You sew daily or use heavy materials.
You notice performance issues like loud noises, uneven stitching, or inconsistent speed.
A technician will adjust the timing, calibrate sensors (for computerized machines), inspect electrical connections, and deep clean inaccessible areas.

Bonus Maintenance Tips
Use the Right Accessories: Always use the correct presser foot and needle plate for your project to avoid jams or needle breaks.
Organize Threads and Tools: Store thread spools away from sunlight and humidity. Use bobbin organizers to prevent tangles.

A sewing machine is a complex, hard-working tool that deserves attention and care. With just 10–15 minutes of regular maintenance, you’ll keep your machine purring smoothly and avoid costly repairs down the line. Make maintenance a habit—it’s one of the best investments you can make for your sewing journey.
