As a common detergent ingredient, sodium hypochlorite plays an important role in household cleaning with its powerful disinfection and cleaning capabilities. However, its irritation and corrosiveness also require users to master the correct method of use to ensure safety and effectiveness.Sodium hypochlorite is irritating and corrosive. Direct contact with the skin or eyes may cause discomfort such as redness, swelling, and pain. Inhalation of its volatile gas may also irritate the respiratory tract. Therefore, protective measures must be taken before use: wear rubber gloves to avoid skin contact, wear protective glasses to prevent liquid splashing into the eyes, and wear a mask to reduce gas inhalation.The cleaning effect of sodium hypochlorite is closely related to its concentration, but too high a concentration may corrode the surface of objects or endanger human health. The concentration of commercially available bleach is usually 5%-6%, and it needs to be diluted according to cleaning needs. For example, when cleaning kitchen countertops, 10 ml of stock solution can be mixed with 990 ml of water to make a 0.05% dilution; when dealing with stubborn stains, the concentration can be appropriately increased to 0.1%-0.2%. Use a clean container when diluting to avoid cross contamination.Different cleaning objects require different operation methods. When cleaning kitchen countertops, stoves and other areas, you can wipe them with the diluted solution, let them stand for 5-10 minutes and then rinse with clean water; when cleaning toilets and floors, you can directly pour an appropriate amount of solution and rinse after 30 minutes; when cleaning floors, you can add the solution to the mopping water, wipe and ventilate to dry. Experiments show that 5% concentration of diluted solution combined with a hard brush to clean the gaps between tiles can remove more than 90% of mildew. Be careful to avoid spraying to prevent the solution from splashing.Sodium hypochlorite needs to be sealed and stored in a cool, ventilated place, away from fire, heat sources and acidic substances to avoid decomposition and failure or causing danger. Unused solution should be discarded within 24 hours. Before discarding, it needs to be diluted with a large amount of water (the dilution multiple is not less than 100 times), or sealed and stored until it is automatically oxidized and decomposed. It is forbidden to pour sodium hypochlorite solution into the sewer and mix it with acidic cleaners such as toilet cleaners to avoid the production of toxic chlorine gas.When using sodium hypochlorite, avoid mixing it with acidic cleaners to prevent chemical reactions from generating chlorine gas; when cleaning home appliances, ensure that the solution does not enter the interior to avoid damaging the equipment; wipe the surface of furniture with clean water to prevent residues from corroding the surface. If it accidentally comes into contact with the skin or eyes, rinse immediately with plenty of clean water for more than 15 minutes and seek medical help; when inhaling volatile gases, move quickly to fresh air, and seek medical attention in time if symptoms such as difficulty breathing occur.As a highly efficient cleaning agent, sodium hypochlorite has significant advantages in household cleaning, but its safe use requires strict compliance with operating specifications. By wearing protective equipment, controlling concentration, standardizing operating procedures, and properly storing and disposing of waste, its cleaning effect can be maximized while protecting the health of users.
