The simplest way to make a hot towel without a microwave is to soak it in hot water from your kettle, stovetop, or faucet, then wring it out. But depending on what you have available and how long you need the towel to stay warm, several methods work well. Here’s how to do each one properly.
The Hot Water Method
This is the fastest approach and the one barbers have used for generations. Boil water in a kettle or heat it on the stove, place a dry towel in a bowl or basin, and pour the hot water over it until the entire towel is saturated. Let it sit for 30 seconds to a minute so the fabric absorbs heat evenly, then wring it out thoroughly.
One important caution: freshly boiled water will make the towel too hot to handle immediately. Either wait two to three minutes before wringing, or use tongs to lift and twist the towel. You can also mix boiling water with a small splash of cold water in the bowl before soaking the towel, bringing it to a comfortable range faster. The goal is a towel that feels pleasantly hot against your skin without burning.
If you’re making a hot towel for shaving, hold it against your face for 30 to 60 seconds. The heat opens pores and softens facial hair, which is exactly why barbershops have made this a ritual for over a century. Once the towel starts cooling, rub it gently against the grain of your beard to lift hairs before you shave.
The Stovetop Steamer Method
If you want a towel that’s evenly heated and extra steamy, use a pot with a lid. Fill the pot with a few inches of water and bring it to a simmer. Roll or fold your towel, place it in the pot (or drape it over a steamer basket if you have one), and cover with the lid for two to three minutes. The steam penetrates the fabric more uniformly than soaking alone, and you get a towel that holds its heat a bit longer.
Use tongs or heat-resistant gloves to remove the towel. Hold it by two corners and let it hang for a few seconds so excess water drips off, then wring. This method works especially well when you need multiple towels in a row, since you can keep the pot simmering and rotate towels through it.
The Slow Cooker Method
A slow cooker is the best option when you need towels to stay warm over a longer period, like during a home spa session or massage. Run your towels under hot tap water, wring them out so they’re damp but not dripping, and place them inside the slow cooker. Set it to high for about 15 to 30 minutes to get them fully heated, then turn it down to low or warm to maintain the temperature.
Massage therapists who use this method in their practice recommend keeping tongs nearby, because towels left on the high setting for more than 30 minutes can become uncomfortably hot to grab with bare hands. Don’t leave damp towels in a slow cooker overnight. One common cautionary tale from professionals: a towel left on the auto setting overnight turned brown and dried out completely. Use this method only while you’re actively monitoring it.
The Hot Faucet Method
The lowest-effort option is simply running your towel under the hottest water your tap produces. Most home water heaters are set between 120°F and 140°F (49°C to 60°C), which is warm enough to make a decent hot towel. Fold the towel into the size you want, hold it under the running water until it’s fully saturated and hot throughout, then wring it out.
The trade-off is that tap water typically isn’t as hot as boiled water, so the towel will cool down faster. This method works fine for a quick facial compress or post-shave towel, but if you need sustained heat for sore muscles or a longer treatment, one of the other methods will serve you better.
Choosing the Right Towel
Cotton holds heat longer and handles high temperatures better than synthetic materials. Thin cotton washcloths and hand towels heat up quickly and are easy to wring out, making them ideal for facial applications. Thicker cotton towels retain warmth longer, which is better for body wraps or muscle relief, but they take more effort to wring and can feel heavy.
Microfiber towels absorb water well but can degrade at very high temperatures. If you’re pouring boiling water over a towel, stick with cotton. For the faucet or slow cooker methods where temperatures are lower, microfiber works fine.
How to Keep a Hot Towel Warm Longer
A hot towel starts losing heat the moment you pull it from the water. A few tricks extend that window:
- Double up. Fold the towel into multiple layers. The inner layers insulate the outer ones, slowing heat loss.
- Seal it in a bag. Place the wrung-out towel in a zip-top plastic bag. This traps steam and prevents evaporative cooling, which is the main reason towels cool down fast.
- Wrap it in a dry towel. Layering a dry towel over the hot one acts as insulation, keeping heat in for several extra minutes.
- Pre-warm your bowl. Rinse your bowl or basin with hot water before placing the towel in it. A cold bowl pulls heat out of the water before it reaches the fabric.
Why Hot Towels Feel So Good
Heat applied to the skin causes blood vessels near the surface to widen, increasing blood flow to that area. This is why a hot towel on sore muscles feels relieving: more blood flow means more oxygen and nutrients reaching the tissue, which helps reduce stiffness and ease minor pain. On the face, the warmth softens skin and hair while the moisture helps loosen dirt and oil from pores.
Keeping Your Towels Clean
Warm, damp fabric is an ideal environment for bacteria. Towels stored in humid areas not only accumulate more bacteria but can develop specific types, including fecal coliform bacteria, that thrive in moisture. After using a hot towel, hang it somewhere with good airflow to dry completely. Drying towels in direct sunlight is especially effective at reducing bacterial growth and preventing odor.
Wash towels you use for hot compresses every three to four uses. Soap and water alone isn’t particularly effective at killing bacteria on fabric, so use the hot cycle on your washing machine and add a disinfecting laundry product when possible. If you’re using towels on your face or on broken skin, a fresh towel each time is the safest approach.
