How to Stop Rust on Cars

Rust can ruin the paint on your car, particularly if it forms in exposed areas where metal is exposed. Rust also consumes metal over time, creating holes or other problems; to stop rust from starting, it’s best to stop it before it begins forming! To prevent further issues with corrosion on your vehicle.

It is also necessary to remove chips, scratches, and dents in the paint and store your vehicle in an area without salt. Furthermore, check undercarriage areas and less visible spots for any sign of corrosion.


Washing your car regularly is crucial. Doing so will remove dirt and grit that may lead to scratches in the paint that expose metal surfaces to oxygen, leading to rusting. Furthermore, any scratches or chips should be addressed soon as they appear so rust doesn’t spread further.

Untreated, even small patches of rust will eventually spread as their surface erodes, chipping away to reveal more and more metal that can become exposed and oxidized – this process is known as scale rusting and, once started, can be pretty hard to eradicate.

To prevent scaling rust, using high-quality car wax regularly to protect its paintwork from weather-induced corrosion and rusting is essential. Rust penetrants like WD-40 may temporarily slow the rate of corrosion and rusting; however, their effectiveness eventually wears off and will need a replacement; for longer-term results, consider investing in KBS Rust Converter, which will convert rust into an inert primer layer protecting from weather exposure or paint over for improved appearance.

Cleaning the Undercarriage

Keep the undercarriage of your car clean to reduce corrosion. A wash with an anticorrosive undercoat or applying an atomized spray directly under it will be an extra barrier against air, moisture, and corrosive salt infiltration.

Inspecting the undercarriage regularly will help identify any signs of rust in and around the wheel wells, door panels, fenders behind tires, and drain holes that could become blocked with debris. Also, ensure drain holes don’t become blocked, as this will ensure the proper functioning of drain holes in these areas.

Once a spot of rust has appeared, it must be treated quickly to stop its spread. Surface rust can easily be removed with a wire brush or sandpaper; be careful only to brush affected areas, wearing a mask as appropriate to avoid breathing in dust from surface rust particles. If left untreated, surface rust may progress into scale-stage rust, penetrating deeper into metal structures and needing further treatment.

Cleaning Drain Holes

Your car’s drain holes help direct excess water away from body parts. Still, over time, they can become clogged with debris, leading to moisture gathering in wheel wells and other details of your vehicle – hastening its corrosion process. If this happens, moisture could accumulate quickly in wheel wells and other places on your car, speeding up corrosion development.

Rust on your car can dramatically lower its value and make life difficult for its next owner, so taking steps to prevent rust is both money- and hassle-saving.

Spraying WD-40 onto an area of rusted metal can quickly dissolve oxidation and expose bare metal, acting as an effective stopgap measure that must be repeated regularly for effective results. Another easy method of dissolving rust is with lemon juice; however, this approach can be messy and may damage paintwork.


Once surface rust has taken root and formed a bubble or hole in the paint, it must be addressed immediately. KBS Klean offers excellent rust remover solutions, followed by an abrasion device until all layers of rust and color have been stripped away, leaving just bright metal exposed before priming and painting.

Of course, the ideal way to prevent rust is to wash your car regularly to remove corrosive debris such as salt and dirt from its body. But for those unable to do this regularly, regular inspection of the car’s body for signs of early rust development, such as bubbling paint or discoloration, should still be an essential task in its own right. Once started, rust quickly spreads uncontrollably unless stopped immediately; for this reason, rust converters may also help stem its spread by converting iron oxide rust to an inert compound that can then be painted over.


In summary, preventing rust in cars involves regular maintenance, protective coatings, and swift action. Addressing rust early and adopting preventive measures can prolong your vehicle’s lifespan and maintain its aesthetic appeal.
