Preventing corrosion (Mazda 3 BK)

You can prevent corrosion. The best way is to keep your car clean. Pay special attention to the underside of your car.

If you live in a region (country) where your car is regularly exposed to corrosive factors – roads are salted, near the sea, in regions with heavy industrial pollution, acid rain, etc. – you should take special measures to prevent corrosion. In winter, spray the bottom of your car with a jet of water at least once a month and rinse it thoroughly after the winter period.

When washing the underside of your car, pay special attention to under-wing and other hidden parts. Do the job thoroughly. Simply washing rather than thoroughly cleaning away accumulated dirt can accelerate corrosion rather than prevent it. Pressurized water and steam are quite effective in removing accumulated dirt and corrosive materials.

When cleaning lower door panels, reinforcements and frame parts, make sure the drainage holes are clear so that moisture can evaporate rather than collect inside and accelerate corrosion.

To avoid corrosion, do not leave your car in a damp, poorly ventilated garage. This also applies if you wash your car inside the garage or drive your car into the garage when it is wet, snowy or muddy. Even keeping your car in a heated garage can promote corrosion if the garage is poorly ventilated and moisture does not evaporate.

Keep paint and trim in good condition. Scratches or chips in paint should be touched up with a touch-up paint as soon as possible to reduce the risk of corrosion. If you find bare metal, take it to a paint shop.

Don't forget about the interior of your car. Moisture can collect under floor mats and carpeting and can also cause corrosion. Be especially careful if you are transporting fertilizers, cleaning materials or chemicals in your car. Transport such materials in special containers and rinse off any spills or stains with clean water and dry thoroughly.
