# formaldehyde strong odor neutralization

One of our customers used a very high dose of formaldehyde 37% solution (60 liter formaldehyde in 40 liter water) for disinfection in his chicken farm (saloon). Now he says the odor of formaldehyde is very strong and can`t start breeding season. How can I help her?

Can he neutralize formaldehyde odor with some chemical treatment? Maybe he can use sodium hypochlorite (bleach). Do you think chlorine can oxidize formaldehyde?

• Just use water and a fan. Bleach will react exothermically and may start a fire. – CoffeeIsLife Nov 19 '16 at 12:06
• No, you don't want to add more water unless you can wash it away. Dampness will "hold" the formaldehyde. This seems to be inside, so you want to use a fan and increase the temperature to dry the place out. – MaxW Nov 19 '16 at 16:44

Ammonia water, AKA ammonium hydroxide ($\ce{NH4OH}$), reacts with formaldehyde to form hexamine, a comparatively innocuous solid (though it is flammable when dry).
