1. Ventilate the Garage:
- Open the garage door and windows to allow for maximum air circulation. This will help dissipate the odor and bring in fresh air.
2. Clean the Affected Area:
- If there are any fish remains or spills on the floor, clean them up thoroughly using a paper towel or a dustpan and broom.
3. Baking Soda and Vinegar Solution:
- Create a cleaning solution by mixing equal parts of baking soda and white vinegar. This mixture creates a chemical reaction that helps neutralize the odor.
- Scrub the solution onto the affected area using a scrub brush.
- Let it sit for about 30 minutes to an hour.
- Rinse the area with water and allow it to dry completely.
4. Activated Charcoal:
- Scatter activated charcoal granules over the affected area. Activated charcoal is known for its odor-absorbing properties.
- Leave it overnight or for several hours.
- Sweep up the charcoal granules and dispose of them properly.
5. Coffee Grounds:
- Similar to activated charcoal, coffee grounds can also absorb odors.
- Sprinkle coffee grounds generously over the affected area.
- Let it sit for a few hours or overnight.
- Sweep up the coffee grounds and discard them.
6. Hydrogen Peroxide Solution:
- Create a solution by mixing hydrogen peroxide (3%) with a small amount of dish soap.
- Scrub the solution onto the affected area and let it sit for about 20 minutes.
- Rinse the area with water and let it dry thoroughly.
7. Commercial Odor Eliminators:
- If the odor persists, consider using a commercial odor eliminator designed for tough smells.
- Follow the manufacturer's instructions for best results.
8. Eliminate the Source:
- Determine the source of the rotten fish odor and eliminate it. Ensure there are no fish remains or spills anywhere in the garage to prevent the odor from recurring.
9. Dehumidify the Garage:
- High humidity can trap odors. Use a dehumidifier to control moisture levels in the garage, contributing to odor reduction.
10. Regular Cleaning:
- Practice regular cleaning and sweeping of the garage to prevent future accumulation of dirt and debris that could contribute to unpleasant odors.
Remember to wear gloves and ensure adequate ventilation while using cleaning solutions. If the odor persists or is overwhelming, consider hiring a professional cleaning service that specializes in odor removal.
