Best Ingredients for a Homemade Car Air Freshener
What You’ll Need
- Baking soda (odor absorber)
- Essential oils (natural fragrance)
- Small mason jar or container with lid
- Fabric or breathable paper
- Rubber band or jar ring
- Push pin or nail
Optional alternatives:
- Activated charcoal (for strong odors)

How to Make a DIY Car Air Freshener (Step-by-Step)
Step 1: Prepare the Container
Use a push pin or nail to poke small holes in the jar lid. This allows the scent to slowly release into your car.
Step 2: Add Baking Soda
Fill the jar halfway with baking soda. Baking soda naturally absorbs odors, making it ideal for car interiors.
Step 3: Add Essential Oils
Add 15–25 drops of your favorite essential oil or blend. Adjust the amount depending on how strong you want the scent.
Step 4: Seal the Jar
Cover the opening with fabric or paper and secure it using the jar ring or a rubber band.
Step 5: Place in Your Car
Put the jar in a cup holder, under a seat, or in the trunk for consistent freshness.

Popular Essential Oil Blends
- Clean & Fresh: Lemon + Eucalyptus
- Relaxing: Lavender + Vanilla
- Crisp & Masculine: Cedarwood + Bergamot
- Energizing: Orange + Peppermint
- Earthy & Natural: Pine + Tea Tree
These blends work well for eliminating odors from food, pets, smoke, and moisture.
Hanging DIY Car Air Freshener Option
If you prefer a hanging air freshener:
- Add 5–10 drops of essential oil to felt, cardboard, or wooden beads
- Let the oil absorb fully
- Tie with string or twine
- Hang from the rearview mirror (avoid obstructing view)
This method is perfect for smaller spaces and quick scent refreshes.
How Long Does a DIY Car Air Freshener Last?
A homemade car air freshener typically lasts 2–4 weeks, depending on:
- Amount of essential oil used

- Air circulation
To refresh, simply add a few more drops of essential oil.
