When cleaning tools, what must be thoroughly removed before disinfecting?

Thoroughly removing debris and dirt before disinfecting is essential in ensuring that the disinfection process is effective. Disinfectants are designed to kill or inactivate pathogens and microbes, and if surfaces are contaminated with dirt or organic material, it can create a barrier that prevents the disinfectant from coming into full contact with those pathogens. This can significantly reduce the efficacy of the disinfection process, leading to potential health risks. By removing any visible debris or dirt first, you can ensure that the disinfectant can work effectively on the surfaces, helping to maintain a safe and hygienic environment for eyelash extension services.

The other options refer to important steps in the cleaning process, but they do not address the critical initial step of removing physical contaminants—debris and dirt—that must be cleared away to ensure effective disinfection.
