How to Remove Decomp Smells in 3 Steps


Odors caused by human decomposition often require specific steps for removal. Organic materials immediately begin to decompose after death, and while it is a completely natural process, it does cause an overwhelming concentration of malodorous compounds. This means that store-bought diluted solutions may not be powerful enough to eliminate smell. While every cadaver will emit pungent odors, the severity is exacerbated by warm climates and time of death. The longer the body sits, the worse it will smell.

It is vitally important to hire professional unattended death cleanup specialists when dealing with a human decomp situation. Some decomposition odors may signal the presence of dangerous chemicals that can be lethal when mixed with domestic cleaning products, such as chlorine and ammonia. This may be particularly true for dead animals that are decomposing in your home without your knowledge. “Animal carcasses are often hidden in crevices of the home or behind layers of sheetrock.” If this is the case, and you’re able to locate the source in your home, you may be able to tackle the decomposition odors.

Step One: Ventilate the area

It’s important to ventilate the area to help remove the odor and keep a flow of fresh air. Open all windows, doors, and other points of entry. Ceiling fans, box fans, and portable fans should be utilized inside the space to help remove the decomp smells.

Step Two: Wash the environment thoroughly

Whether you need to clean a hard surface floor, carpet, or furniture, there are a few universal measures you should follow:

  • Always wear protective garments, such as gloves, a disposable apron, and a face mask or goggles/respirator.
  • Always use a registered disinfectant product with a broad spectrum kill claim.
  • Always wipe odorous areas from the outside toward the center to avoid spreading.

You may use equal parts white vinegar and water as an additional cleaning step. Wet the area, let it sit for several minutes, and pat it dry with a lint-free rag.

Step Three: Absorb the odors

To help ensure that the decomposition odors are permanently removed, set a bowl of vinegar or baking soda near the cleaned area. This will help absorb any lingering smells. Keep in mind that the bowls should be placed well out of reach of pets and young children.
