The answer to 'my house cleaning is filthy' is that there are several common causes, such as lack of regular cleaning, buildup of dirt and grime, or ineffective cleaning methods. Symptoms may include visible dirt, dust, and stains on surfaces, unpleasant odors, and an overall feeling of uncleanliness.
Some solutions include establishing a regular cleaning routine, using the right cleaning products and tools, and addressing any underlying issues like mold or pest infestations. However, if the problem is severe or you don't have the time or ability to clean thoroughly, it's best to call in a professional cleaning service.
