Battery Corrosion and DIY Tips for a Clean Start

Battery corrosion is a common issue that many car owners encounter when popping open their hood. This phenomenon occurs when sulfuric acid in the battery reacts with lead on the terminals, forming a corrosive compound known as lead sulfate. While this reaction is a natural part of a battery's aging process, several factors can accelerate the corrosion, turning it into a nuisance for car owners.

Why Do Batteries Corrode

Climate and temperature fluctuations, especially heat, can expedite the chemical reactions leading to battery corrosion. If you live in an area with frequent temperature fluctuations, your battery may be more susceptible. Continuous overcharging of the battery can accelerate the production of hydrogen gas, contributing to terminal corrosion. Ensure that your vehicle's charging system is functioning correctly to avoid overcharging.

Old age is another factor that makes a battery more prone to corrosion. Regular maintenance and timely replacement can help mitigate the effects of aging on your battery. Improperly installed or excessively tightened terminals can disrupt the integrity of the battery connection, leading to corrosion.

How to Tackle Car Battery Corrosion with this DIY Method

When tackling battery corrosion, safety should be the top priority. Before attempting any cleaning, wear protective gear, including gloves and safety glasses, and disconnect the battery cables, starting with the negative terminal.

Baking Soda and Water

One effective method for cleaning corrosion is to create a solution by mixing baking soda with water to form a paste. Apply this paste to the corroded areas using an old toothbrush or a dedicated battery cleaning brush. For stubborn corrosion, a vinegar solution can be effective. Soak a cloth in vinegar and gently wipe away the corrosion.

After cleaning, please remember to use a wire brush to scrub away the remaining corrosion on the battery terminals. Ensure that the brush is specifically designed for battery cleaning to avoid damage. To prevent future corrosion, apply an anti-corrosion spray or petroleum jelly on the terminals.

Once the terminals are clean and dry, reconnect them starting with the positive terminal followed by the negative terminal. Ensure a snug but not over-tightened connection.

By understanding the factors contributing to battery corrosion and implementing these simple DIY tips, you can bid farewell to the pesky white powder on your battery terminals. Regular maintenance, coupled with these cleaning techniques, will not only extend your battery's life but also ensure a start every time you turn the key.

What’s Causing That Grinding Noise When I Brake?

August 29, 2025

Brakes are one of the most important safety features on your vehicle, and any unusual noise when braking should be taken seriously. A grinding sound is especially concerning because it often points to worn parts that could compromise your stopping ability. Ignoring it can lead to more expensive repairs and reduced safety on the road. Knowing what causes brake grinding and acting quickly can help you avoid bigger problems. Worn Brake Pads The most common reason for grinding brakes is worn brake pads. Brake pads have a friction material that wears down with use. Once this material is gone, the metal backing plate makes contact with the brake rotor every time you press the pedal. This metal-on-metal contact creates a loud grinding sound and can quickly damage the rotors. Replacing pads before they wear down completely not only prevents grinding but also protects the rotors from costly damage. Damaged or Worn Rotors If you’ve been driving with worn pads for too long, your rotors may have deep grooves or scoring. This damage can also create a grinding sound, even after new pads are installed. Warped rotors from excessive heat can cause vibrations along with noise, making braking less smooth and less effective. In some cases, rotors can be resurfaced, but often they need to be replaced to restore safe, quiet braking. Debris Caught in the Brakes Small stones, rust flakes, or other debris can get lodged between the rotor and the brake pad. This creates a constant grinding or scraping noise when you brake or even when driving without braking. While this is less common, it’s still important to address it immediately since the debris can score the rotor’s surface and reduce braking performance. Caliper or Hardware Problems Brake calipers hold the pads in place and press them against the rotors when you brake. If a caliper is sticking or if the hardware is damaged, it can cause uneven pad wear, overheating, and grinding noises. A sticking caliper can also make the vehicle pull to one side while braking and can quickly overheat the brakes. Lack of Lubrication in Brake Components The moving parts of the braking system, such as caliper slides and contact points, need to be properly lubricated to operate quietly. Without lubrication, these parts can seize or wear unevenly, leading to noise and reduced braking efficiency. Why You Shouldn’t Ignore Grinding Brakes Driving with grinding brakes can cause serious damage to your braking system. Metal-on-metal contact wears down components quickly, increasing repair costs and making your car unsafe to drive. In extreme cases, you may lose braking ability altogether. Even if the grinding turns out to be caused by something minor, it’s better to have it checked early than to risk major brake failure. Diagnosing the Problem A professional brake inspection will include checking the thickness of the pads, the condition of the rotors, and the operation of the calipers. The technician will also look for debris, damage, and signs of overheating. From there, they can recommend the right repair—whether that’s replacing pads and rotors, cleaning out debris, or servicing calipers and hardware . Preventing Brake Grinding Routine brake maintenance is the best way to prevent grinding. Have your brakes inspected regularly, especially if you drive in heavy traffic, tow, or travel in hilly areas where brakes work harder. Replacing pads before they wear down completely keeps the rest of the braking system in better shape. Also, pay attention to early warning signs like squealing or squeaking when braking. These sounds often mean the pads are getting thin and need replacement soon.
