Bleach is a powerful cleaning agent commonly used for disinfecting and whitening surfaces. It typically contains sodium hypochlorite, which helps kill bacteria, viruses, and fungi. Bleach is effective on various materials, including fabrics, countertops, and bathroom surfaces, making it a popular choice for household cleaning. When using bleach, it is essential to dilute it with water to ensure safety and effectiveness. Always follow the manufacturer's instructions and wear protective gear, such as gloves and masks, to avoid skin irritation and respiratory issues. Proper ventilation is also crucial when using bleach to minimize exposure to harmful fumes.
