Tools/raw materials: white vinegar, green tea
1, white vinegar in addition to formaldehyde is not suitable. Liquid white vinegar has no effect on free formaldehyde in the air.
2. Prepare a cup or bowl, pour a proper amount of green tea, soak it in a proper amount of white vinegar, and seal it with plastic wrap.
3, sealing is to prevent white vinegar from volatilizing and affecting the effect. Poke some holes in the plastic wrap with a toothpick and put it in the room, in addition to formaldehyde.
note:
Formaldehyde is insoluble in water or vinegar, but soluble in water vapor. If vinegar is boiled, the steam of vinegar can dissolve some formaldehyde, but the problem is that this solution is unstable.
If this solution can't be moved outdoors in time, then formaldehyde will be released from this solution at any time. At first, vinegar can only temporarily cover up the formaldehyde smell in the house with a strong vinegar smell.
