Can sodium hypochlorite spray gun be used for disinfection in kitchens and bathrooms?

Sodium hypochlorite spray guns can be used for disinfection in kitchens and bathrooms, but attention should be paid to operating procedures and safety precautions (as explained in the following points):

1、 Applicable scenarios
Kitchen disinfection is suitable for spraying areas such as countertops, sinks, cutlery racks, and trash cans, which can effectively kill common bacteria and viruses such as E. coli. But it is necessary to avoid food processing areas (such as cutting boards and knives that need to be cleaned separately after use) to avoid residual contamination.
Toilet disinfection can be sprayed on the inner and outer walls of the toilet, washbasin, ceramic tile gaps, etc., to remove mold, dirt, and scale, and decompose odors. The effect is significant for areas prone to mold such as shower room glass and floor drains.

2、 Usage restrictions
Material compatibility issues
Not suitable for metal products (such as stainless steel faucets, aluminum doors and windows), sodium hypochlorite may corrode the surface of carbon steel and aluminum materials.
Avoid using on fabrics: may cause fading or damage to clothing or carpets.
Handle paint/plastic with caution: Strong oxidation may damage the paint layer or aged plastic.
Do not mix other cleaning agents, especially with acidic products such as toilet cleaner, as it may produce toxic chlorine gas.

3、 Operational suggestions
The recommended effective chlorine concentration for general object surfaces is 250-500mg/L (such as 1:100 dilution of 84 disinfectant), which can be increased to 1000mg/L in heavily polluted areas, with a duration of action of ≥ 10 minutes.

Spray gun adaptation requirements
A check valve is required to prevent liquid backflow from damaging the motor.
After spraying, let it stand and then wipe off any residue with clean water.
Personal protection and environmental safety
Wear rubber gloves and keep ventilation during operation to avoid inhalation of spray.
Do not aim the spray gun at people or pets to avoid irritating the mucous membrane.

4、 Alternative Proposal
If it is necessary to disinfect food contact items such as cutting boards and knives, or metal surfaces, it is recommended to use pure hypochlorous acid disinfectant (not sodium hypochlorite), which has lower corrosiveness and wider applicability.
