Baking soda is cheap, easy to find, and extremely versatile.

Although it is best known for its uses in the kitchen and household cleaning, it also has surprising functions in the automotive sector.

Many mechanics and enthusiasts use the product safely and conveniently in various situations. Here are the main uses for car care.

Cleaning Parts and Engines

One of the most popular uses of baking soda in automobiles is cleaning metal parts. It can be mixed with water to form a light abrasive paste, capable of removing grease, dirt, and even superficial rust.

Additionally, it is common to use baking soda in blasting, especially to clean components such as:

Cylinder heads
Engine blocks
Carburetors
Intake manifolds

This method cleans without damaging the original surfaces.

Odor Elimination Inside the Car

Baking soda is also effective at neutralizing bad smells in the car, such as:

Cigarette
Food
Mold

The process is simple: sprinkle baking soda over the seats and carpets, let it sit for a few hours, and vacuum. The result is a more pleasant interior environment, without the use of expensive products.

Headlight Restoration and Glass Cleaning

Another use frequently mentioned by mechanics and content creators is in restoring yellowed headlights. Just mix baking soda with water or vinegar to form a slightly abrasive paste. The application helps to remove the cloudiness from plastic lenses.

On the glass, baking soda can also be used to efficiently remove grease and stains.

Do Not Use in the Radiator

Some videos suggest using baking soda to clean the cooling system. However, this use is not recommended.

Although it helps remove residue, baking soda can react with aluminum and rubber components.

Baking soda can facilitate many car care tasks.

If used correctly, it helps keep the vehicle clean, functional, and smelling good—all at a very low cost.

It is one of the simplest but most effective secrets in the automotive mechanics industry.

Other Curious Uses of Baking Soda in Daily Life

Besides the automotive sector, baking soda also stands out in other practical situations at home.

Odor Neutralizer in the Refrigerator

Just place a cup of baking soda in the back of the refrigerator. It acts directly on the odor molecules, eliminating the smell without masking it. Replace the cup every three months to maintain its effectiveness.

Stain Remover for Carpets

To remove stains from carpets, the process is simple:

Sprinkle baking soda over the stain.
Spray a mixture of water and vinegar (1:1 ratio).
Wait for it to dry for up to an hour.
Scrub with a brush and vacuum.
Finish with a damp cloth, if necessary.

This combination produces carbonic acid, responsible for the effervescence that helps in stain removal.

Engineers want to carve through Africa with a giant canal to bring water from the world’s second-largest river to a dying lake on the edge of the Sahara Desert that has already lost 90% of its water.

Brazil filled the Northeast with wind turbines but now faces the side effect of 705 giant blades reaching the end of their lifespan by 2032 just in Rio Grande do Norte, while the world projects 43 million tons of waste by 2050.

India approved the country’s first submerged road-rail tunnel, 15.8 kilometers dug under the bed of the Brahmaputra River.

Instead of burning or burying old tires, an American city is transforming about 2,000 of them into the street itself, paving its first sections with a quieter and more durable rubber asphalt.

In just one cast, fishermen are surprised to capture 14,096 mullets in Bombinhas and close a historic season with 58,000 fish; scene recorded in the Santa Catarina paradise marks the last day of the 2026 season.

10 giant tortoises are reintroduced and, in just 6 months, trigger changes that lead scientists to investigate a phenomenon absent for 180 years; the numbers recorded on the island impress researchers from around the world.

Greek island offers free housing for volunteers, but there’s a condition: you need to take care of rescued cats.

What many people consider a weed has become a bicycle in the hands of a Chilean. José Tomás transforms coligüe, a native bamboo that grows up to five times faster than pine, into bikes, canes, and cutlery.

Only 28% of the ocean floor has been accurately mapped, less than what is already known about the surface of Mars and the Moon, and scientists consider the topic strategic for Brazil, with a global goal to map everything by 2030.

Japan wants to bury a 500 km “cargo conveyor” between Tokyo and Osaka to replace up to 25,000 trucks per day, move goods through tunnels and automated driverless corridors, and avoid a logistical collapse in an increasingly aging country.

GAC launches “Chinese hybrid Kombi” with 7 seats cheaper than Tiggo 8 Pro Plug-in Hybrid in Brazil; for around R$ 177,000 in conversion without taxes, the Trumpchi E8 PHEV has a 2.0 engine, DHT transmission, an electric range of 150 km, and a premium family cabin for those living in China.

Electric and hybrid cars receive flood warnings: brands limit crossing to 20 or 30 cm, recommend up to 10 km/h, and warn that water on the floor can contaminate batteries, render systems unusable, and void the warranty.

Suzuki sells a “family 4×4 SUV” with 5 doors, 1.5 engine, ladder frame chassis, 4×4 traction with reduction gear, and a price equivalent to about R$ 66,000 without taxes, below the Jeep Renegade sold in Brazil: meet the Jimny 5-Door in India.

Stellantis sells the “French family van” with up to 7 seats, a 100 hp diesel engine, a trunk of up to 775 liters, and a price equivalent to about R$ 153,000 without taxes, below the Tiggo 7 Pro Max Drive sold in Brazil: meet the Rifter.

Forget Kwid or BYD Dolphin! The cheapest popular electric car in Brazil costs R$ 69,000, exceeds 200 km of range, and arrives costing up to R$ 56,000 less than well-known rivals.
