No, house cleaners or cleaning services do not need to be certified or licensed. Each state has its own requirements for licensing and certifications for companies, but most states don't require any special training to clean a home. Be sure to check our state licensing tool to review the local guidelines for house cleaners and cleaning services.

To hire a professional house cleaner, start by searching for local services online and asking friends or colleagues for recommendations. Review company websites, social media accounts, and online customer reviews to understand their business and reputation. Contact prospective cleaners to ask about their services and charges. It's also a good idea to meet with them in your home so they can see the scope of the job, allowing you to discuss expectations and negotiate a price. Always do thorough research before choosing a cleaning service to ensure it’s the right fit for you.

One of the best ways to prepare for a home biohazard cleanup is not to touch anything. Do not remove belongings, even if they are of value or importance, from the area as they are likely contaminated. It’s essential not to use any cleaning products of your own, as the cleaning company will be using chemicals that could interact with your products. 

One thing you can do to prepare is take pictures of your space and belongings that need to be cleaned, especially if you plan on filing a claim with your insurance company. In addition, take time to make a list of items that are valuable, sentimental, or otherwise important. The cleanup company must evaluate these belongings to make sure they are safe. 

To clean an old dishwasher without a filter, start by removing the bottom rack to access the drain area. Use a damp cloth or sponge to wipe down the interior, paying special attention to the corners and crevices where food particles and debris can build up. Pour a cup of white vinegar into a dishwasher-safe bowl and place it on the top rack, then run a hot water cycle to help break down grease and grime. After the cycle, sprinkle a cup of baking soda across the bottom of the dishwasher and run a short hot water cycle to deodorize and further clean the interior.
