The answer to 'why is my kitchen filthy' is that there are several common causes, including lack of regular cleaning, spills and messes not properly cleaned up, buildup of grease and grime, and improper food storage. Symptoms may include visible dirt, stains, and odors, as well as the presence of pests like insects or rodents.
To address a filthy kitchen, start by establishing a regular cleaning routine. Wipe down surfaces, sweep and mop floors, and clean the oven, stovetop, and sink on a weekly basis. Pay special attention to areas where grease and food particles accumulate, like behind the stove or under the sink. If the problem persists despite regular cleaning, it may be time to do a deep clean or call in a professional cleaning service.
