in fact, I have used formalin & KMnO4 for disinfecting a tissue culture lab & growth room, but the smell have not removed after 4 days, how can I get ride of it? any practical method to recomand?
You could try either white vinegar or baking soda but don't try both at the same time.
you keep on all of the ventilators of your lab open for 4 to 5 hours continuously. Hope it will be cleared. It depends on your lab structure
It is super easy. You can purchase both of items. Heinz distilled white vinegar and ARM and HAMMER baking soda is the exact name of those items.
I ment that, I should spray the liquid around or I should put it somewhere to absorb the smell?
Please swipe the floor with it. There is an indication on container, how to use it.
Where I stay, I have cheap wild lime available in plenty. Lime juice can be another choice in place of white vinegar . But only when it suits your conditions. Dilute the juice with 2 times the water for spraying. I put a bowl full of it 1 feet from the ducts of air inlet for my growth room and we got somewhat relieved from the smell. For large spaces i agree with what prosanta suggested
Provide ample air circulation over-night followed by spray of any lime/vinegar solution.
Dear Dr. Pazuki
I'm totally agree with you about source of contamination, but when a commercial lab face infection, it becomes a different story than research lab scale works. Despite my unwillingness for using toxic chemical, only this way, I could make sure about disinfection.
