why are winters so bad for vehicles? salty roads, cold morning starts, and damp weather that makes your car rust are certainly not good for your vehicle.

is there anything that can be done to prevent damage to your car? well, that is why we are here. in this article, we will talk about how to prevent winter damage and rust.

the best way to protect your car from rust during the winter and prevent rust is to wash the car at least once a month. you can also apply wax to the paint and add extra rust protection to the underbody.

here’s a more detailed list of how to protect your car from rust during winter:

1. regular car washes

car wash

snow in winter covers all roads and paths and makes it difficult for you to drive your vehicle. the city authorities use salt to melt the ice and clear the road.

using salt is good for the road, but it is terrible for vehicles. if you drive on salted roads, the salt will stick to your vehicle everywhere and increase the risk of corrosion and rust.

to prevent this from happening too much, it is a good idea to have your vehicle washed regularly.

try to wash your car at least 1-2 times per month during the winter to keep the rust and salt away. you often have to use special products to get rid of all rust and salt in the paint job.

we do never recommend going to automatic car washes because they are often damaging the paint. however, we also understand that many people do not have their own garage to wash their car.

you can often find car washing companies that are washing your car manually, and we strongly recommend this.

2. apply wax to the paint job

you want to prevent dirt and salt from accumulating on the body of your vehicle. this can be easily prevented by applying an extra layer of wax to the paintwork after your car washes.

the wax does not allow dirt to stick to the car and prevents the formation of rust. the areas where the car is most exposed, such as the chassis and the area near the wheels, require special care in winter. so don’t forget to get your car in shape just before the onset of winter.

3. rust protection

today there are many rust protection products on the market that can be applied to your car’s chassis. the underbody is most exposed to salt, water, and snow and is, therefore, most susceptible to rust damage. a single layer of rust protection can extend the life of your car.

you can either do this yourself or let an auto body shop do this for you. doing it yourself can be quite time-consuming if you do not have the right tools for it.

many newer cars have either a lot of plastic covers under the car protecting them for this. however, it can get dirt stuck under these covers, which will cause rust, and it is recommended to remove these plastic covers to check for rust sometimes when you have your car raised.

4. clean the drains

all cars have drains in certain areas that prevent water from stagnating in one place. there are drains in the doors and parts of the fender. these drains can be blocked by dirt or leaves that prevent water from escaping.

in such cases, instead of draining water from the body, they block the vehicle’s water and promote rust.

you will also found a few of these under the car’s rocker panels and in other places underneath the car. check under the cars for any holes that look blocked. you often have a hose from under the front windshield going under the car, which needs to be drained and clean.

the interior of the car must also be protected from moisture. when you get into your car, you often bring some snow or salt with you. this snow or salt may not be present in large quantities, but even a small amount can be lethal. there may come the point where the floor of your car gets rusted, and then your chassis becomes weak.

you have to prevent this from happening, and all you need to do is buy all-weather mats. these mats do not allow water, dirt, or other materials to get onto the carpet. in this way, they protect the floor and at the same time allow you to remove the harmful contents from the car without damaging anything else.

6. undercoating with oil

undercoating oil

we talked about rust protection products and how they prevent corrosion under the car. but we did not mention that these products are a bit expensive. some of you may not be able to afford rust protection.

fortunately, there’s a hack for that. we can borrow the expertise of old farmers who undercoated their trucks and tractors with used oil to prevent rust. the waste oil serves no other purpose and cannot be reused in a vehicle, which is used as underbody rust protection.

the oil absorbs all the dirt and salt from the roads and does not allow any of it to pass onto the metal. as long as the metal is protected from harmful materials, it stays in good shape.
