Cleaning and oiling your sewing machine: what the manuals say

The machine makes a new noise, the stitch comes out uneven, the thread breaks for no obvious reason. Before assuming something's broken, remove the needle plate: underneath you'll very often find a grey felt of lint and bits of thread. Cleaning is the one piece of maintenance every machine needs. Oil is a different matter, and here manufacturers disagree: some forbid oiling, others ask for it every day.

Why lint matters

With every stitch the thread passes through the fabric, and both thread and fabric shed fibres. They collect where the machine forms the stitch: around the feed dogs, the metal teeth that poke through the needle plate and move the fabric forward, and in the hook, the catch under the plate that grabs the needle thread and interlaces it with the bobbin thread.

Brother explains it on the support page for one of its computerised machines: if dust and dirt collect in the hook race or the bobbin case, the machine won't run well and the bobbin thread sensor may fail to react. Elna writes that loose threads and dust can cause puckered stitches and thread breakage, and recommends checking for lint at the end of every project.

How often to clean depends on how much you sew. Manuals give different guidance: Singer and Pfaff say to clean under the plate "after several projects, or when you notice a build-up"; Elna, every time the machine has been used for an extended period; the manual for a Janome mechanical machine with a front-loading bobbin recommends roughly every three months.

What to use, and what not to

On tools, the manuals we read agree:

• the small brush (the one supplied) and a soft, dry cloth; Brother, Janome and Elna also allow a small vacuum cleaner;
• no compressed air: Bernina says not to use spray compressed air, Brother that canned air isn't recommended, and Singer and Pfaff explain why: blowing pushes dust and lint further into the machine;
• no sharp tools near the hook (Bernina) and no solvents on the casing: Janome and Juki recommend a cloth with a little mild detergent.

Brother adds a warning about the bobbin case: if it's scratched, don't use it, because the upper thread can tangle and the needle can break. Take a look at it while you clean.

Oil: it depends on your machine

Here the instructions diverge, sometimes even within the same brand. The table below sums up the manuals we read: each row applies to the machine type stated, not to the whole brand.

There's really only one rule: follow your machine's manual, not a general rule. If the manual says oil isn't needed, don't add any: Brother writes that the machine shouldn't be oiled precisely to avoid damaging it, and Janome that oil can ruin the bobbin holder. If the manual does point to lubrication spots, on the other hand, oiling them is part of normal use.

When oiling is called for, the manuals agree on the details:

• only sewing machine oil, ideally the one the manufacturer specifies: Brother warns that another type of oil can damage the machine;
• just a few drops: Bernina reminds you that too much oil stains the fabric and the thread;
• clean first, then oil: Bernina and Juki have you remove the hook or the case before oiling;
• afterwards, sew a test piece on a scrap, which soaks up the excess oil (Janome, Juki, Bernina).

The type of hook can be recognised by where the bobbin goes in: from above in a horizontal hook, from the front in a vertical one. The difference is explained in Rotary or oscillating hook. As of 19 September 2026, of the 58 published sewing machines and sewing-and-embroidery combos in our catalogue, 19 state their hook type: 15 horizontal rotary, 3 vertical oscillating, 1 vertical rotary. This is our catalogue, not the market.

Overlockers and industrial machines

The overlocker produces more lint than a sewing machine, because its knives trim the fabric as it sews: Singer's manual says as much at the start of its maintenance chapter, and calls for frequent oiling because the machine runs at very high speed. For industrial machines the lubrication system varies from model to model: among those in our catalogue that state it, as of 19 September 2026, 6 have automatic lubrication, 6 semi-dry, 1 dry and 2 manual. The model's own manual always applies.

When you need a service centre

Cleaning and oiling don't replace a technician. Brother gives a clear signal: if the handwheel (the wheel on the right side, used to turn the machine by hand) becomes stiff, or the machine makes an unusual noise, stop using it and go to an authorised service centre. Bernina's computerised machines show a message when the scheduled maintenance interval has expired. Consumer Reports, in its buying guide (updated in 2016), suggests a service at least every two years, more often if you sew a lot.

While you clean, check the needle too: a worn needle gives symptoms similar to a dirty hook. When to change your needle explains when; if the problem is tangles of thread under the fabric, start from Thread nests and skipped stitches.

In brief

• Brush the feed dogs and hook with the small brush and a dry cloth, often. No compressed air.
• Before oiling, open the manual: many modern domestic machines shouldn't be oiled, others should, sometimes every day.
• If oiling is called for: sewing machine oil, a few drops, test on a scrap.
• A stiff handwheel or new noises: a service centre, not oil.
