Natural air fresheners for your car If you have been unable to prevent your car from smelling, there are some ways you can eliminate the smell with natural solutions. Here are some ideas: Lemon odor neutralizer: 2 cups of ionized water 1.5 teaspoon baking soda 1 tablespoon of lemon juice Simply mix these ingredients together and put into a spray bottle. The natural lemon fragrance should help freshen up the smell while the baking soda will help absorb it. Spray around the car and use it along with your cleaner when getting rid of stains. White vinegar This doesn't even need an ingredient list. Simply put some white vinegar into a spray bottle and spray it on the affected area with the odor. The vinegar will penetrate as well as the foul smell and eliminate it. Don't overuse otherwise your car will simply smell of vinegar. Once you get rid of the smell, wash the area with your usual cleaner. Coffee grounds Used coffee grounds can be used to soak up the air in the car. It won't work for major smells, but can work for minor ones. Also be careful when using coffee grounds in your car if you have white upholstery. Hydrogen peroxide While you may not think of it, hydrogen peroxide is naturally occurring. Although not usually in the amounts you get from the bottle. Still, it is a great odor eliminator and should be used if these other natural smell blasters don't work. 2 cups 3% hydrogen peroxide 1/8 cup baking soda 1 splash of natural soap Mix these ingredients together and put into a spray bottle. Use as an odor eliminating cleaner. Best advised to leave on for a couple of hours before rubbing away. NOTE: ensure to make a fresh batch of this one before you use it. It won't be effective if it has been sitting out for two long. The others should still work even after a couple of months.
