What should disinfectants never be used on?

Disinfectants are specifically formulated to eliminate bacteria, viruses, and fungi on surfaces, making them suitable for use on non-living materials. However, they should never be applied to human skin. This is because disinfectants can contain harsh chemicals that may cause irritation, burns, or allergic reactions when used on the skin.

Furthermore, using disinfectants on hair and nails can lead to damage. Hair and skin are sensitive, and applying strong chemicals could disrupt their natural balance, leading to adverse effects. Similarly, disinfectants can alter the integrity of fabrics, potentially leading to fading, weakening, or degrading the material.

In this context, it is crucial to understand that disinfectants are intended for surfaces and tools rather than for direct application to skin, hair, or fabrics, thus supporting the idea that they should never be used on any of these options.
