The second one uses baking soda and salt. If the slippers only smell, but the inside is not particularly dirty, then we can put some baking soda and then some salt in the shoes, brush them evenly with a brush, and then put them in a ventilated place for one night. The next day, we will find that the smell is very small. The third kind uses white vinegar and baking soda. First, prepare a watering can, which is filled with appropriate amount of water, then add appropriate amount of white vinegar and baking soda and shake well.
Spray slippers evenly on every part of the shoes with a small watering can, then cover the shoes with clean toilet paper and press for about 15 minutes, and then take off the toilet paper, and the shoes will be clean. Spray a little more into your shoes, then put them in a ventilated place for one night and you can wear them immediately the next day. The fourth method is direct sunshine, but this method has limitations and is suitable for better weather.
Put the cotton slippers directly in the sun, preferably in a strong and ventilated place, and put the inside of the shoes facing the sun. After a few days of exposure, the odor will naturally decrease. Although dry cleaning is easy to use and convenient, for health reasons, it is suggested that cotton slippers should be washed with water once a month as much as possible, because they will be washed thoroughly. After all, slippers are not only dirty and smelly, but also may lead to bacteria and other diseases.
