Step 1: Open all the windows

To get rid of the odor of untreated sewage, open all of the windows in the house.

Step 2: Use vinegar to remove the sewer smell

To eliminate the raw sewage smell in your house, load a plastic spray bottle with concentrated white vinegar. To minimize sewage and other odors, position your spray bottle some inches away from your furnishings and sprinkle. In addition, sprinkle hard surfaces to remove sewer smells in the same manner. After a few hours, the vinegar smell dissipates.

Step 3: Use baking soda

To remove the untreated sewage odor, put baking soda on your floor, let it lie overnight, and vacuum completely using a vacuum cleaner. Baking soda, much as in your refrigerator, removes bad scents on your floor. Ensure you use the correct amount and remember to open the windows in the morning for fresh air.

Step 4: Use charcoal pieces

Cut the charcoal into smaller pieces that are recommended. Arrange the charcoal pieces in a small saucepan and place numerous bowls throughout your house. Charcoal removes odors and helps to purify the air.

Step 5: Use some scented agents such as sprays

To eliminate intense sewage gas scents, sprinkle a perfumed odor remover into the air and soft surfaces. These items come in a range of smells and can be found in most supermarkets. Ensure you use the best spray that does not increase allergic reactions, especially for those people within the house with allergy issues. If there are any, first, let them get out or choose moderate perfumed odors.

Step-by-step guide on how to clean a house with sewer smell
  • House sink smells

Sinks in both the kitchen and the bathroom can emit foul sewer smells. Water shortage in the trap, like in shower facilities and toilets, can cause sewage odors to rise via the sink drainage. These smells are most likely to be created in sinks that are rarely used, such as in the house base, sheds, or washrooms.

If organic waste is causing your sink to stink like a sewer, eliminating and properly cleaning the fragments may help eradicate the stink. The sink components such as the p-trap and pivot rod can all be removed from the sink and soaked in a solution of warm white vinegar. Pour hot down the drain after rearranging the pieces to eradicate any leftover microbial debris.

  • House toilets

Flush a medium stockpot of hot water down the toilet, then add the baking soda to the water-filled drain. Allow it to sit for a time. Allow at least 25 minutes for 2 cups of white vinegar to dissolve in one cup of boiling water. Flush more water down the drain or toilet. Because toilets link directly to a septic system, sewer odors are generally the worst in the house. 

  • House shower drains

Fortunately, all you have to do to get rid of biofilm in your shower drain is clear out your pipes. Clear drains to the p-trap with detergent, warm water, and a brush before rinsing with lukewarm water to get rid of future odors. Sewer odors are most usually caused by rarely used shower drains.

The water in the p-trap can dissipate if not used frequently enough; sewage gasses can enter without water in the trap. As a result, keep your shower clean and disinfected to avoid any unpleasant scents. This type of stink usually goes away after a few minutes of running water.
