u want to get rid of the weed smell in your car, there are certain ways you can achieve it. For instance, you can make use of the super odor-absorbing qualities of baking soda by sprinkling a small amount on the carpets and the seats. Leave it for good twenty-four hours and then clean it away using a vacuum cleaner. Other than that, you can also make use of activated charcoal in place of baking soda, whichever is easily accessible to you.
