The reason why adding two towels increases cleaning power when washing backpacks

Laundry expert manager An Hyeong has revealed specific methods to increase cleaning power by utilizing two towels when washing backpacks and to prevent the deformation of cotton T-shirts. According to the video 'In Search of a Laundry Expert' on the Setakseol YouTube channel, to remove contamination inside a bag, it must be turned inside out for washing, and the key is the 'bat effect' using towels.

Why backpacks should be turned inside out and washed with two towels

Backpacks used by students often have more contamination on the inside than on the outside. Manager An Hyeong emphasizes that when washing a bag, it must be turned inside out before being put into the washing machine. This is because if the bag is not turned inside out, the dust or foreign substances accumulated inside will not be properly removed. Additionally, all zippers should be left open so that detergent and water can penetrate well into the interior for smooth rinsing. If washed with the zippers closed, detergent and water may not enter the interior sufficiently, which can prevent proper rinsing.

The secret to maximizing washing efficiency is utilizing 'towels.' Instead of putting only the bag into the washing machine, you should put two towels in together after twisting and tying them. When towels are twisted and tied, they act like a bat inside the washing machine. When the towels absorb water, they gain weight, and this weight creates an effect of pounding every corner of the bag using gravity, thereby strengthening the cleaning power. Two towels must be used instead of one so that they move along with the bag inside the washing machine to wash without gaps. This is because if only one towel is used, it may go inside the bag or stay in one place.

For washing settings, it is recommended to select the standard course, set the water temperature to 40 degrees Celsius considering children's skin, add one extra rinse, and set the spin strength to 'medium.' Using about 70cc of detergent is appropriate.

The 'Towel Safety Belt' laundry method to prevent cotton T-shirts from stretching

The phenomenon where cotton T-shirts twist to one side or lose their shape after washing is a concern for many. Manager An Hyeong suggested a method called the 'Towel Safety Belt' to prevent this. After washing is finished, take the wet clothing and shake it with your hands to restore its original shape, then place the clothing on a wide towel and roll it up like a kimbap.

If you proceed with spinning while wrapped in a towel like this, you can prevent the clothing from shifting to one side or losing its center of gravity in the washing machine, which causes stretching. In particular, if the spin strength is set to 'strong,' the spinning occurs while the clothing wrapped in the towel is in a lightened state, which can also reduce the phenomenon where the shoulder part bulges out. If the spin is weak, a phenomenon where the clothing stretches downward 'like a trumpet' can occur due to the weight of the water, so strong spinning is the key. Additionally, during summer or the rainy season, spinning while wrapped in a towel like this is effective in quickly removing moisture and reducing laundry odors.

How to quickly dry the inside of a backpack without melting the waterproof coating

When you need to dry a backpack quickly after washing, using a dryer recklessly is dangerous. Many backpacks have a special coating for waterproofing, and if strong heat from a dryer is applied, this coating can melt, causing the bag to lose its function. If the coating melts, the waterproof function disappears, which can cause problems where books inside get wet when it rains.

Manager An Hyeong introduced a drying method using old rubber gloves. The method involves cutting off three of the finger parts of the rubber gloves, fixing them to the opening of the bag, and then pushing a hair dryer into the inside of the bag. Because the air is dispersed to every corner of the bag's interior through the cut finger holes, you can quickly dry the interior while preventing direct contact with hot heat. At this time, caution should be taken to use 'medium' wind rather than 'strong' wind from the dryer to avoid damaging the internal coating. Using this method, a significant amount of moisture inside the bag can be removed in just one minute.

Finally, to prevent the shoulder straps of a backpack from causing pilling on clothes, applying a little fabric softener to the shoulder strap area can also be helpful. This has the effect of making the straps soft and lowering the frictional resistance with clothes, preventing the fabric from being damaged when carrying the bag.
