Dettol 99% of germs wiped out (DETTOL)

Dettol products are widely marketed with the claim that they kill 99.9% of bacteria, viruses, and fungi. This, or a similar 99% figure, is a standard claim for many household disinfectants, indicating a high level of effectiveness against common germs, including E. coli, S. aureus, and various viruses, when used as directed.

Here is a breakdown of what this "99.9% germs wiped out" claim means:
Scientific Meaning (Log Reduction): The "99.9%" figure refers to a "3-log reduction" in germ population during laboratory tests. If a surface has 1 million bacteria, a 99.9% reduction means approximately 1,000 bacteria could still survive.
Not 100% Sterile: The claim means the product is effective at reducing the number of germs significantly, but it does not make a surface or hands completely sterile. The 0.1% of germs that remain can still reproduce.
Conditions Apply: The 99.9% effectiveness is achieved under specific laboratory conditions with precise "contact times" (the length of time the disinfectant stays wet on a surface). Real-world application might vary, especially if surfaces are heavily soiled or if the product is wiped off too quickly.
Targets Specific Germs: While effective against a wide spectrum, not all disinfectants kill every type of microorganism. Dettol is effective against many pathogens, including COVID-19, cold and flu viruses, and bacteria like Salmonella.
Why Not 100%? It is legally and scientifically safer to claim 99.9% because proving 100% elimination (sterilization) on all surfaces, every time, is impossible.

Key Takeaway: Dettol is highly effective at reducing the risk of infection by removing the vast majority of germs from hands and surfaces, making it a reliable choice for hygiene, but it should not be expected to remove 100% of all micro-organisms.
