Baking soda is a versatile, non-toxic cleaner you can use on your car for several specific tasks, primarily focusing on deodorizing and gentle cleaning. It's highly effective at neutralizing odors in the cabin, cleaning battery terminals, and lifting light stains from fabric and carpets. However, it's an abrasive powder and should be used with caution on delicate surfaces like painted finishes or glass, as it can cause micro-scratches.
The most common and safest use is eliminating stubborn smells. Sprinkle a generous amount on your car's upholstery and carpeting, let it sit for 15-20 minutes to absorb odors, and then vacuum it thoroughly. For a more targeted approach against smoke or food smells, you can leave an open box in the cupholder overnight.
Another great application is cleaning battery corrosion. Mix baking soda with a little water to create a paste. With the car off, apply it to the corroded battery terminals and cable connectors. The paste will fizz as it neutralizes the acidic corrosion. After scrubbing with a dedicated battery brush, rinse completely with water and dry before reconnecting. This is a crucial maintenance step for ensuring good electrical contact.
For washing the exterior, it's not recommended for the paint. Instead, you can make a paste to clean chrome accents or polished aluminum wheels. Apply the paste, gently scrub with a soft cloth, and rinse well. Always test any cleaning method on a small, inconspicuous area first to ensure it doesn't damage the surface. While baking soda is a handy household solution, it's not a substitute for professional-grade automotive cleaning products for deep cleans or paint correction.
