Jeyes Fluid is a disinfectant and cleaning product commonly used for outdoor cleaning tasks such as clearing drains, removing moss and algae, and disinfecting outdoor surfaces. It has a strong smell and is often diluted with water before use.
Disinfectants are used to kill germs on non-living surfaces, while antiseptics are used to kill germs on living tissues.
