Not all disinfectants are effective—choose the right ingredients and pay attention to concentration.
1. Medical Alcohol
75% concentration is most effective. If the alcohol concentration is too high, dilute it to around 75% before use, otherwise it won't effectively kill viruses.
2. Chlorine-based disinfectants
In daily life, products like 84 Disinfectant, bleaching powder, chlorine-based disinfectant powder, or chlorine effervescent tablets all fall under this category.
When using 84 Disinfectant, never use it undiluted. Wear a mask and rubber gloves. Dilute it with cool water at a ratio of 1 part undiluted solution to 100 parts water before use.
A simple dilution method recommended by experts is to add one capful of 84 Disinfectant to two bottles of 500ml cool water (pour cool water first, then add 84 Disinfectant).
Additionally, chlorine-based disinfectants should not be used simultaneously with toilet cleaners, as this can produce toxic gases. They are also not recommended for use with alcohol, as disinfection effectiveness may be reduced or toxic gases may form.
3. Peroxide-Based Disinfectants
Chlorine dioxide, hydrogen peroxide, and peracetic acid are representative substances in this category.
Chlorine dioxide disinfectants are low-toxicity and highly effective, making them suitable for household disinfection when used correctly according to instructions. Peracetic acid is flammable, explosive, and highly irritating, so it is not recommended for home use.
Note: All disinfectants possess some toxicity. They should not be used to disinfect fruits, vegetables, or tableware. Instead, they can be used to wipe down corrosion-resistant surfaces like countertops, tables, chairs, light switches, and bathrooms. After disinfection, ensure proper ventilation by opening windows. Wipe surfaces clean with water 30 minutes later.
