15 Minutes in Boiling Water Eliminates Bacteria Trapped in Tea Towels

Fifteen minutes of boiling is the minimum time required to kill bacteria embedded in tea towel fibers, according to a method promoted by chef Charles Kim, known online as Chef Fatty. Kim argues that standard washing machine cycles fail to remove deep-seated odors because they do not reach the interior of the fabric where microbes thrive.

Kim states that using standard laundry detergent can exacerbate the problem. He explains that excess detergent and fabric conditioner leave a waxy residue on the fibers. This buildup traps body oils, dead skin cells, and moisture, creating an environment where odor-causing bacteria grow. Kim warns against washing stinky towels in the machine, telling viewers, "Never ever ever wash a stinky towel. Let me explain."

The recommended process involves filling a large bucket or saucepan with boiling water and adding approximately two tablespoons of washing soda. The towel is then submerged and boiled for at least 15 minutes. This method bypasses the mechanical action of a washing machine, relying instead on heat and alkalinity to break down grime.

Washing soda, chemically known as sodium carbonate, is a more potent cleaner than the baking soda (sodium bicarbonate) found in most pantries. Kim notes that washing soda can be purchased ready-made or created by heating baking soda in an oven at 180 degrees Celsius for 30 minutes. This heating process triggers a chemical reaction that removes water and releases carbon dioxide gas, increasing the pH level. The higher pH makes the solution more effective at cutting through grease and softening hard water.

For households without a large enough container for boiling, Kim offers an alternative machine method. He advises setting the washing machine to its hottest cycle and using oxygen bleach powder along with detergent. He emphasizes that fabric softener must be avoided in all cases, as its residue contributes to the waxy buildup that traps odors.

The method addresses a common household issue where towels remain damp for extended periods, allowing mildew and bacteria to breed. By eliminating the waxy film left by conditioners and using high heat, the fibers are cleared of the debris that standard washes fail to extract.

Kim’s guidance positions the boiling method as a direct counter to the conventional advice of adding more detergent when towels smell. Instead of increasing chemical load, the technique reduces additives to just water and soda, ensuring the fabric is fully rinsed and free of trapped organic matter.
