How to make a strong car air freshener

Updated February 21, 2017

People are on the go in their cars more than ever, leaving odours to lurk in car interiors from food, gym gear or pets. An economic way to keep those stinky smells away is making homemade car air fresheners. With hundreds of fragrance oils and oil blends available on the craft supply market, you can make a custom air freshener in a scent to please your nose and your passengers' noses too.

Pour 2 cups of the crushed corn cob into the glass container. The container should be large enough to leave ample room for the mixture to move around when shaken.

Pour 29.6ml. of fragrance oil into the container and close the lid tightly.

Shake the jar to disperse the oil through the mixture. Shake again every few hours over the next two days. This allows the oil to soak into the crushed corn cob and helps the air freshener to cure so it will last longer when in use.

Measure a 10-inch square of fabric with a ruler and mark the measurements with a fabric marking pencil.

Cut the square out with pinking shears. The pinking shears cut a v-shaped edge that is resistant to fraying.

Cut a piece of the ribbon or yarn 12 inches long. You can use multiple ribbons together to give the sachet more colour.

Pour 1/3 to 1/2 cup of air freshener mix onto the middle of the fabric square. Gather up the fabric sides around the mixture with the ribbon until a ball is formed and no mixture can be seen.

Tie the ribbon in a bow around the sachet. Arrange the gathered fabric so it is distributed evenly around the sachet.

Cut additional ribbon and tie it to the back the sachet if you would like to hang the sachet on your car's rear view mirror. Otherwise set the sachet under a car seat or in another place where the oils will not damage plastic or stain upholstery.


You can also use commercial potpourri or dried lavender blooms in place of the crushed corn cob mixture to make a sachet for the car. Make a sachet with a cloth drawstring bag purchased in a local craft store, or sew a small bag to hold the scented material.


Some fragrance oils can damage and stain wood, plastic, painted surfaces and fabric. They also can irritate skin.
