Smoke smell and odors typically will not go away completely on their own, especially once the particles have penetrated porous materials like walls, floors, ceilings, and furniture. While airing out affected items can help the smell subside over time, it often lingers for months or even years. To effectively remove stubborn smoke odors, you should combine several methods. Start with a thorough deep cleaning and deodorizing using substances like baking soda or activated charcoal. Air purifiers can also help capture airborne particles. In severe cases, you may need to replace heavily damaged materials. If the smell persists after repeated treatments, consider hiring a professional smoke damage restoration company for assistance.

The Centers for Disease Control and Prevention (CDC) recommends using an EPA-registered disinfectant product to disinfect a house properly. If such a product isn't handy, a strong bleach solution can disinfect high-touch surfaces. Before hiring a professional, be sure to discuss the type of chemicals and disinfectants they plan to use to ensure they’re safe for household use.

While a biohazard cleanup sounds like a scary process, knowing what to expect can help ease your concerns and set you up for success. It’s good to note that more than one professional might be needed depending on your situation, but that will be determined during the assessment. What you can expect during a home biohazard cleanup is the following:

• Assessment: The first step in this process is for a biohazard cleanup professional to assess the damage. They create a report that includes the biohazard safety level, the needed damage cleanup, and the time it should take to complete the project. 

• Setup: The cleanup professional prepares the site to prevent cross-contamination and reduce toxicity risk. This process can include tarping and creating decontamination zones. 

• Removal of surface contamination: Any contaminated materials are removed from the area, starting with large materials followed by small ones. The professional can assess any floor-related damage once everything is removed from the site. 

• Salvaging items: The biohazard cleanup professionals assess which items can be saved and which are contaminated beyond the point of saving. Those deemed unsafe will be disposed of immediately. 

• Waste disposal: The next step is carefully disposing of the hazardous waste. Your professional will place the contaminated items in specific containers to keep the contamination from spreading.   

• Disinfection: The house will be disinfected and odor-neutralized. Even more minor details, like light switches and bulbs, will be disinfected so that they do not recontaminate the area in the future. 

• Restoration: Once the decontamination is complete, the last step is to restore the home. This includes repairing the damage to flooring, walls, or even the home's foundation.  

The main difference between a general cleaning and a deep clean is that a general cleaning focuses on regular maintenance, while a deep clean hones in on the nitty gritty details of cleaning that may not impact your day-to-day life. For example, it’s important to wipe down your counter and have a clean place to cook regularly, but you may not think twice about pulling out your stove to clean behind it until it’s time for a deep cleaning.
