How to Clean the Owlet Smart Sock and Sensor

An Owlet fabric sock and sensor sit against a baby's skin for hours, so oils, lotion, detergent residue, and moisture can contribute to irritation and poor contact. Cleaning directions vary by generation; the steps below follow Owlet's Smart Sock 3 guidance, including turning the sensor off, washing the fabric separately, and spot-cleaning rather than submerging the sensor. Check the exact Smart Sock or Dream Sock model before starting and never put a damp sensor on a child or charging station.

What you will need

  • The Owlet instructions for the exact sock generation
  • The gentle laundry detergent already used for the baby's clothes
  • Cool to lukewarm water in a sink, basin, or bowl
  • A clean, soft-bristled toothbrush
  • A clean, dry towel

Step-by-step instructions

Step 1: Confirm the generation and turn the sensor off

Use the Owlet app or base-station sequence specified for the exact model to turn the sensor fully off. Confirm its light is off. Smart Sock 2, Smart Sock 3, Dream Sock, and newer products may not share identical wet-cleaning instructions, so do not assume one generation's method applies to another.

Step 2: Separate the sensor and fabric

Remove the sensor from the fabric sock. Set up a diluted solution of cool-to-lukewarm water and a small amount of the gentle laundry detergent already tolerated in the baby's clothing. Owlet cautions against hand soap, antibacterial soap, and dish soap because residue can be drying or irritating.

Step 3: Hand-wash the fabric sock

Submerge the fabric part only and gently work the solution through soiled areas. Rinse it under clean water until all detergent is removed. Do not use bleach, fabric softener, or harsh stain remover, and do not twist the straps or hook-and-loop fasteners out of shape.

Step 4: Spot-clean the Smart Sock 3 sensor

For Smart Sock 3, dip the soft toothbrush bristles in the diluted detergent solution and tap away excess so they are damp rather than dripping. Gently brush the sensor in small circles without submerging it. Rinse the toothbrush, tap out excess water, and repeat with clean damp bristles until dirt and every trace of detergent are removed.

Step 5: Blot and air-dry completely

Press the sensor gently into a dry towel and leave it on the towel to air-dry. Blot the fabric and lay it flat or hang it to dry. Avoid a dryer, direct sunlight, and applied heat, which can warp parts. Drying time depends on airflow and humidity; use dryness, not a fixed number of hours, as the test.

Step 6: Inspect, reassemble, and restore power

Do not use a damp sensor on a child and do not put it on the charging station. When both pieces are completely dry, inspect the fabric fit and sensor window, reinstall the sensor in the correct orientation, and restore power using Owlet's instructions. Verify normal status before the next wear.

Specific cleaning questions

Open a question for a concise answer about stains, odors, safety, frequency, and troubleshooting.

How often should I clean an Owlet Smart Sock 3?
Owlet's Smart Sock 3 instructions say to clean the fabric sock and spot-clean the sensor every two weeks. Clean sooner after lotion, visible soil, heavy sweat, or detergent contamination. Other generations may specify a different method, so check their support page.
Can the Owlet sensor be submerged?
Do not submerge the Smart Sock 3 sensor. Owlet's method uses a soft toothbrush dampened with diluted detergent solution, followed by repeated brushing with clean damp bristles. Keep the sensor off and remove excess water from the brush before contact.
Can an Owlet fabric sock go in the washing machine?
Follow the instructions for the exact generation. The Smart Sock 3 support method hand-washes the fabric in diluted detergent solution, then rinses and air-dries it. Machine agitation and heat can change fit or damage fasteners.
Which soap should I use on an Owlet sock?
Use a small amount of the gentle laundry detergent already used for the baby's clothing. Owlet cautions against hand soap, antibacterial soap, and dish soap. Rinse repeatedly because detergent left on the sensor or fabric can irritate skin.
Why is there a red mark under the Owlet sock?
Dirt, oil, trapped moisture, soap residue, pressure, or incorrect fit can contribute to irritation. Stop use and check cleaning, dryness, size, placement, and strap tension. Seek medical advice for persistent, worsening, blistered, or concerning skin changes rather than diagnosing the mark from a guide.
Can I charge an Owlet sensor while it is damp?
No. Owlet warns that placing a wet sensor on the charging station can cause failure. Blot and air-dry it completely at room temperature. Do not use a hair dryer, radiator, or direct sunlight to speed the process.
How do I remove lotion or diaper cream from the sensor?
Turn the sensor off and remove it from the fabric. Use the Smart Sock 3 damp-toothbrush method with diluted familiar laundry detergent, then repeat with clean damp bristles until no residue remains. Never scrape the optical area with a hard tool.
Why does the Owlet lose readings after cleaning?
Check that the sensor and fabric are completely dry, the sensor is seated in the correct orientation, the fabric is not stretched, and the sock fits as the model instructions show. If readings remain unreliable, use Owlet support instead of recleaning with stronger chemicals.
