How to Stop Rust on your Car

Your car is probably one of your most cherished possessions. However, after some time, you start noticing some rust on the edges and surfaces. This not only makes the appearance of your car less appealing but also diminishes the market value of the vehicle significantly. Over time, the rust eats up the car’s structure and causes major mechanical issues that interfere with its performance.

Removal of rust can be a nightmare for most car owners. Luckily, if you are already experiencing rust problems, there are foolproof tips that you can use to stop rust on your car. Here are is an insightful guide to prevent rust on your vehicle and save you lots of repair costs and frustrations.

Wash and Wax your Car Regularly

This may sound obvious, but it is one of the most important ways to stop rust on your vehicle. Typically, most car owners choose to wash their cars just once a month. This leaves an ample amount of time for dust as well as debris to continue causing harm to the car leading to the formation of rust.

Also, organic compounds present in bird droppings may lead to chemical reactions on the coat of the vehicle, causing further damage if not cleaned. Automatic fluids such as automatic transmission fluids are also leading causes of rust formation when they spill on the car surface.

Wash and Wax your Car Regularly


  • Wash your car thoroughly after every two weeks.
  • Wash the car once every week during the winter when roads are usually salty or if you live near the ocean.
  • Add a tablespoon of baking soda to your water and soap to help neutralize salt acidity together with other ice-melting chemicals.
  • If your car is at too much risk of being damaged by rust due to salty roads, you can spray the underside with a high-quality car lubricant.
  • Use automotive soap when cleaning.
  • Always clean the inside of the car thoroughly and dry spills on the surface immediately to prevent the accumulation of rust.
  • Use a car cover to prevent the car surface from accumulating dust, debris animal droppings, among other chemicals when you are not using.
  • Wax the car every once per month to prevent any chances of damage by water through oxidation.

Inspect thoroughly for early detection of rust

Another important way to stop rust on your car is to inspect for rust. Try to identify all the spots where rust can find its home. The exterior surfaces indicate the presence of rust when you see blisters or bubbles on the paint. The blisters and bubbles are usually an initial stage of the commencement of rust. Advanced rust, on the other hand, has a reddish-brown color and displays a flaxy texture. Advanced stubborn rust often damages the car surface at an incredibly fast rate and, if not stopped, causes irreversible damage.

The other two areas that are most susceptible to rust include the undercarriage as well as the car engine. Use a flashlight for the inspection, so it is easier for you to identify the rusty parts. Always remember to inspect the wheels, side-mirror connection points, the antennae, drain holes, and other places where body components meet. Remember that if you do not identify rusty spots early enough, it may cause irreversible damage to the affected area, and you may have to replace the whole part immediately with a custom made one.
