How to Clean the Owlet Smart Sock and Sensor
The Owlet Smart Sock is a vital baby monitor that tracks your infant's heart rate and oxygen levels. Because the fabric sock sits directly against your baby’s sensitive skin, dirt, sweat, diaper creams, and skin oils can build up quickly. Regular washing prevents skin irritation (which is often mistaken for electronic burns) and ensures the optical sensor can read through the fabric accurately. However, because the sensor contains highly sensitive electronics, you must clean it with extreme care. Here is how to do it safely.
What You Will Need:
- Mild, baby-safe laundry detergent (liquid is best)
- Cool to lukewarm water
- A soft microfiber cloth
- Dry cotton swabs (Q-tips)
- A clean, dry towel
Step-by-Step Instructions
Step 1: Separate the Sensor from the Fabric Sock
Before doing any cleaning, always remove the plastic sensor dome from the fabric sock. Never submerge the electronic sensor in water or place it in a washing machine, as liquid will permanently destroy the sensor.
Step 2: Hand-Wash the Fabric Sock
Fill a small bowl or sink with lukewarm water and add a few drops of mild baby laundry detergent. Submerge the fabric sock and gently rub it between your fingers to clean it. Avoid using harsh chemical stain removers or bleach, as these can irritate your baby's skin and degrade the elastic.
Step 3: Clean the Sensor Lens
Take a dry microfiber cloth and gently wipe the flat optical window (the lens) on the bottom of the electronic sensor. If there is stubborn residue (like dried lotion), lightly dampen a cotton swab with water, wipe the lens window, and immediately dry it with the dry side of the swab.
Step 4: Squeeze and Air Dry the Sock
Do not wring or twist the fabric sock, as this will stretch out the elastic and make the sensor fit incorrectly. Instead, lay the wet sock flat on a dry towel, fold the towel over, and press down to squeeze out excess water. Lay the sock flat in a dry area to air dry. Never put the sock in a clothes dryer.
Step 5: Ensure 100% Dryness Before Reassembly
Wait until both the fabric sock and the electronic sensor are 100% dry before popping the sensor back into the sock. Reassembling them while damp can trap moisture inside, causing the sensor to fail and creating a breeding ground for bacteria.
Frequently Asked Questions & Troubleshooting
Why is my baby getting a red mark from the Owlet Sock?
Red marks are almost always caused by skin irritation (contact dermatitis) from dirt, moisture, diaper cream, or soap residue trapped under the fabric, or from the sock being strapped too tightly. It is rarely an actual burn. Washing the fabric sock weekly and ensuring it is completely dry before use will prevent this.
Can I put the Owlet Sock in the washing machine?
No. Hand washing is highly recommended. The washing machine can stretch the delicate fabric, ruin the velcro, or shrink the sock, which will prevent the sensor from aligning correctly against your baby's foot.
How often should I wash the Owlet Sock?
For optimal hygiene and sensor performance, you should wash the fabric sock once a week. If your baby has naturally sweaty feet or if diaper cream is used, you may need to hand-wash it twice a week.
