How to remove sand and salt water from your car | AMPER practical guide
Returning from a day at the beach always leaves great memories… and a not-so-pleasant little "gift": sand everywhere and traces of saltwater in your car. 🏖️🚗
The most annoying part is that the sand can scratch upholstery and paint, and the salt accelerates corrosion on the bodywork and undercarriage, not to mention the damp odors that get embedded in the seats.
At AMPER, we know that your car is more than just a means of transport: it is your adventure companion. That is why we have prepared this practical guide to remove sand and saltwater easily, quickly, and safely, protecting every corner of your vehicle with professional products.

Why is it important to remove sand and saltwater from the car?
- Sand acts like fine-grit sandpaper: it gets into floor mats, seams, and surfaces, causing micro-scratches on plastic, leather, and paint, not to mention that it can lead to health issues, especially if you have allergies.
- Saltwater contains chlorides that accelerate oxidation and corrosion, especially on metal areas and screws.
Fun fact: salt can also leave white stains on fabrics and glass if allowed to dry without rinsing.
Step-by-step guide to remove sand from the car

1. Shake out floor mats and seats
- Remove floor mats and shake them out outside the car to loosen accumulated sand.
- If you use seat covers, remove them and shake them out.
2. Vacuum with a narrow nozzle
- Use a powerful vacuum with a thin attachment to reach crevices, between the seats, and under the pedals.
- Make short, repeated strokes to lift embedded sand.
3. Gently brush the upholstery
- For more stubborn sand, a soft-bristled brush helps loosen it without damaging the fibers, so you can then follow up with a cloth and tapimox to eliminate stains and remaining sand without fading the fabrics.
How to remove saltwater and prevent corrosion
1. Rinse with fresh water
- Wash the bodywork and, above all, the car's undercarriage with plenty of fresh water.
- This neutralizes the salt and stops it from continuing to affect the metal.

Fun fact: in Spain, many car wash tunnels offer programs starting from about €5, and if the establishment uses a good car shampoo like our Deter Auto , your car will come out clean and protected.
If you prefer to do it yourself at home, dilute Deter Auto according to the instructions and apply with a sponge, rinsing afterward with plenty of water.
2. Dry thoroughly
- Use microfiber cloths to dry the paint and avoid limescale marks.
- Open the doors and trunk to ventilate and dry out any moisture.
3. Clean plastics and the dashboard
- Saltwater can leave sticky residues on interior surfaces. You can apply a special plastic cleaner like Brisol, which acts as a protector and moisture repellent for future trips to the beach.
4. Treat specific stains
- If saltwater left white stains on glass or chrome, use a professional glass cleaner, which is fast-drying and leaves no streaks or prints.
At AMPER we have the perfect range of products to keep your vehicle impeccable, from upholstery cleaners to plastic polishers.
