The answer to 'my maid service is filthy' is that there could be several common causes, such as poor training, lack of supervision, or use of substandard cleaning products and equipment. Symptoms may include visible dirt, dust, and grime, unpleasant odors, and an overall sense that the cleaning is not up to par. To address this, you should first try communicating your concerns directly with the maid service and giving them an opportunity to correct the issues. If that does not resolve the problem, it may be time to consider finding a new, more reliable maid service.
When dealing with an unreliable maid service, it's generally best to avoid attempting DIY cleaning solutions, as that could lead to further issues. Instead, it's recommended to work with a professional cleaning company that has a proven track record of quality service and customer satisfaction.
