1. How to Wash Thermal Underwear
- Fully dissolve neutral washing powder in warm water.
- Soak the thermal underwear in water below 40 degrees Celsius and add the dissolved washing powder.
- Gently rub it with your hands, or place it in a laundry bag and wash it gently in the washing machine.
- Ensure each washing process does not exceed 20 minutes.
- Rinse off the washing powder with water, gently wring to remove moisture, and then lay it flat. If necessary, use a towel to lightly absorb water by rolling up the underwear. Finally, air-dry it; avoid baking or placing it on a radiator.
2. Precautions for Washing Thermal Underwear
-
Do not dry clean.
- Dry-cleaning may leave a significant amount of detergent, causing skin discomfort and long-term adverse effects.
-
Use neutral detergents.
- Detergents should be neutral and bleach-free. It is recommended to use special detergents like laundry soap, soap powder, or soapy water, dissolved in warm water before application. The water temperature should not exceed 40 degrees Celsius.
-
Do not dehydrate vigorously.
- After washing, avoid wringing out moisture or using a washing machine to spin dry. Instead, gently squeeze water from the underwear or lay it flat on an absorbent towel to remove excess water.
-
Do not expose to the sun.
- Smooth the underwear by hand before drying. Hang it on a hanger with sleeves to prevent deformation. Avoid exposing it to the sun or using a heater, as it can damage thermal fibers.
-
Do not iron.
- Avoid ironing thermal underwear to preserve the air static layer and enhance thermal performance.
3. How Often to Wash Thermal Underwear
Thermal underwear worn close to the body should be washed weekly to prevent bacteria growth from sweat absorption. Thermal underwear not worn close to the body can be cleaned every two weeks to preserve thermal performance. Spot cleaning is recommended for minor dirt, as frequent washing may damage the thermal layer.
