Safety Precautions
Lint, dust, and other debris should be removed from the feeding device of a sewing machine regularly for optimal performance. Before cleaning the feed dog, always unplug electric machines from their power sources. This prevents accidental electric shock and other accidental damages. Mechanical machines that operate with pedal feet should have their feet turned off before cleaning the feed dogs. It is also advised to check the unit’s manual to make sure on how to remove the top of the machine, if necessary.
How to Clean
To begin, use a can of compressed air or an air blower to blow away the lint and dust from the feed dog and the spaces around it. To pick out lint and debris that won’t budge, an artist brush can be used. Dampen an old toothbrush then use it to scrub the feed dog and its hard to reach parts. If this does not work, use tweezers to pick out debris and lint from the small spaces around the feed dog. If the feed dog is still dirty, diluted dishwashing soap soap can be used on it.
Reassemble and Test
Once done cleaning, the feeding device should be reassembled and checked to ensure that everything is in its right place and correctly adjusted. Once the cleaning is done and the machine reassembled, assemble the top of the machine and plug it in. Test the machine on scrap fabric to check if the feed dog is operating correctly.
Check the Feed Dogs
To determine if the feed dogs need to be cleaned, check their surface carefully. If they are covered in lint or don’t seem to be gripping the fabric, then cleaning them is necessary. If the feed dogs have developed rust or if the fabric isn’t feeding properly, then it might be time to replace them.
Avoid Damage To feed Dogs
It is important to keep the feed dogs lubricated regularly to keep them from becoming damaged from rust, mold, or corrosion. It is also advised to keep petroleum-based oil away from the feed dog. Although it might seem easier to use a drop or two of oil for lubricating the feed dogs, it can damage the unit.
Maintenance
While cleaning and maintaining sewing machines, it is also important to check the other components too. The bobbin, presser foot, feed dogs and needle should all be regularly inspected and changed as needed. In fact, replacing the needle with a brand-new one at least every other project helps keep the unit operating correctly and prevents needle breakage.
How to Clean the Bobbin Case
To keep the bobbin case clean, remove the bobbin case and the bobbin, and inspect the area around the case and the bobbin, wiping away any dirt, lint, and debris that appears. Also, use a can of compressed air to blow away any excess lint and dirt that won’t budge with a brush or Q-tip. An old toothbrush moistened with diluted dishwashing soap can be used to scrub away tough debris.
How to Clean the Roller
The roller of the sewing machines should be cleaned by removing the housing of the machine. This part is usually located around the back of the machine. Once the casing is removed, use cotton swabs and an artist brush to clean the roller. Also, a thread cleaner can be used to remove and pick out lint, dust, and debris.
How to Clean the Bobbin Spool and Tension Disc
To clean the bobbin spool and tension disc, begin by unplugging the machine and removing the cover plate and screw. Then, use a can of compressed air to blow away lint and debris. A thread cleaner can also be used to clean these parts. Make sure to clean the spring tension disc. Lastly, replace the missed screw and cover plate before plugging the machine in and testing it.
Cleaning the Presser Foot
To clean the presser foot, begin by unclamping the screw that holds the foot. Use a lint roller to clean the presser foot and its hard to reach parts. Once cleaned, miss the screw and plug in the machine for testing.
Cleaning the Feed Dog Teeth
The feed dog teeth should be cleaned with a damp cloth. When wiping the feed dog teeth, move from the center part outward. This part of the cleaning is important to ensure that the feed dog teeth are not damaged or misshapen.
Test the Feed Dogs
To effectually test the feed dogs, set the stitch length of the machine to the longest possible length before testing. This ensures that the feed dog can move properly and effectively. Therefore, after plugging in the machine and testing it, if the fabric isn’t feeding properly, then it’s time to clean the feed dogs!
