A steam fumigation method for sobering up, using a 24cm aluminum pot with a steaming grid, put a measuring cup under the steaming grid, add 2.5g potassium permanganate and 5ml 40% formaldehyde (formalin) solution, put the silk thread on the steaming grid, and fumigate for 1 hour, which can achieve the purpose of disinfection, and the silk thread will not become brittle.

All metal instruments, glass, enamel, etc. Rinse with clean water after use, and pay special attention to the decontamination of ditches, grooves and shaft joints. And metal utensils should also be oiled and rusted;

Heat distilled water with high temperature fumigation machine, and then spray water vapor on the furniture surface. The principle of utilization is that formaldehyde has strong volatility, and the higher the temperature, the faster the formaldehyde volatilizes. High-temperature steam quickly heats the surface of furniture, thus accelerating the volatile decomposition of formaldehyde.
