The Science and Practice of Dishwashing
Dishwashing, also known as dish cleaning or washing dishes, is the process of removing food residue, grease, and dirt from plates, utensils, cookware, and other kitchenware. It is an essential household task performed either manually using hands or through an automated dishwasher. Dishwashing helps maintain hygiene by preventing the buildup of bacteria and foodborne contaminants. Proper dishwashing techniques ensure cleanliness and prolong the life of kitchen items.
1. What you`ll need:
Proper dishwashing involves the use of specialized cleaning agents, such as detergents or soaps, along with mechanical action provided by tools like sponges, brushes, or scrubbers, rather than relying solely on water. These agents and tools effectively break down grease, remove food particles, and eliminate bacteria, ensuring a higher standard of cleanliness and hygiene. The following is a list of essential tools and materials required for optimal dishwashing efficacy:
1.1. Dish soap
Dish soap is a powerful warrior in the fight against stubborn grease and grime commonly found on dishes. It's engineered to combat oils and fats, ensuring that your dishes come out free from any lingering residue that could compromise food safety.(Can you use… n.d.)
Examples of what not to use as a dish soap:
1.2. Sponge or a scrubber
Using a sponge or scrubber is necessary for effective dishwashing because these tools provide the mechanical action required to remove food particles, grease, and biofilms from surfaces. While detergents break down oils and fats, the physical scrubbing action dislodges debris and ensures thorough cleaning. Sponges and scrubbers also increase friction, helping to reach crevices and textured surfaces that water or detergent alone cannot clean. This combination of mechanical action and chemical cleaning ensures higher hygiene standards, reducing the risk of contamination from bacteria and food residues.
Optimal utilization of a sponge includes periodic disinfection by placing it in a microwave for 30-40 seconds after use. This method effectively reduces microbial load by exposing the sponge to high temperatures, which destroy bacteria and other microorganisms that can proliferate in the moist environment of the sponge. Regular microwave treatment helps mitigate the risk of cross-contamination and ensures that the sponge remains hygienic for future use.

1.3. Dish towel or drying rack
After washing, it is crucial to thoroughly dry dishes to inhibit bacterial growth, as moisture provides an ideal environment for microbial proliferation. Proper drying—either by air-drying or using a clean towel—ensures that dishes remain sanitary for future use. Additionally, drying eliminates residual water spots and improves the overall aesthetic and tactile experience for subsequent users, enhancing both hygiene and user satisfaction.
After you have washed dishes in hot, soapy water, you can use a dish towel to dry them. In general, it’s okay to dry your dishes with a towel as long as the towel you use is clean. The advantage of using a towel is that you can dry dishes thoroughly and quickly, then put them away. TIf you decide to air dry your dishes, consider letting them dry on a clean dish towel or a cleaned dish rack. Always check your dish rack to ensure no mold or mildew is starting to grow on it.
