Alcohol: The Quick-Evaporating Cleaning King
75% alcohol has strong sterilizing power, rapidly absorbing moisture from bacterial proteins and killing bacteria. It is stable, evaporates quickly, and is easy to carry, making it a must-have for many people. Suitable for personal hygiene and household disinfection, alcohol works well on phones, doorknobs, and public spaces. However, alcohol may dry out the skin, so moisturizing after use is recommended.

Bleach: An Effective Household Cleaning Assistant
Sodium hypochlorite, the main ingredient in bleach, has powerful sterilizing effects. Mixing 5% bleach with 100 parts water creates a 500 ppm disinfectant, perfect for wiping doorknobs, tables, and mopping floors. However, bleach has a strong odor and may irritate the skin, so gloves and good ventilation are necessary for safe use.

Natural Antibacterial Solutions: The Safest Option for All Ages
For households with children, elderly, or pets, natural antibacterial agents such as grapefruit seed extract are ideal. Free of harmful chemicals, they are highly effective, safe for food-grade use, and can even be used as antioxidants in beverages. This multipurpose solution is safe and non-toxic for the whole family.

Hypochlorous Acid Water: Effective but Requires Proper Use
At 100-300 ppm concentrations, hypochlorous acid water is highly effective in killing bacteria. After spraying, it needs to sit for at least 5 seconds before wiping for best results. Although it has a mild odor, homemade versions may lose potency quickly, so proper storage is important.

Chlorine Dioxide: Strong Sterilizer, Not Recommended for Home Use
Chlorine dioxide, a man-made gas, is highly effective at eliminating bacteria and viruses in water treatment, swimming pools, and wound care. While effective, its safety for regular household use remains debated, so frequent home use is not advised.

Nano Silver: Powerful Physical Antibacterial Agent with Hidden Risks
Nano silver physically disrupts bacterial cell structures and blocks virus reproduction, killing over 600 types of bacteria and viruses, even enteroviruses. However, as a heavy metal, its long-term health effects remain uncertain, raising concerns among parents. It’s effective but should be used cautiously.

Choose the Right Antibacterial Solution for Safer Homes
When selecting disinfectants, natural options like grapefruit seed extract are recommended for their safety, simplicity, and long shelf life. In addition to choosing the right product, proper usage is crucial. Only by maintaining a clean environment can we protect our families during a pandemic. Let’s practice good prevention habits and make our homes safe havens!
