Keeping your car's interior clean improves its appearance, driving comfort, and the durability of its materials. However, many people make simple mistakes that can lead to stains, premature wear, or permanent damage.

## Mistake 1: Using Household Products in the Car Interior

One of the most frequent mistakes. Automotive plastics, vinyl, leather, and fabrics have specific finishes that can be damaged by aggressive chemicals — even products that seem mild can have an incorrect pH for these materials.

Always use products specifically designed for car interior cleaning that remove dirt without compromising the materials.

## Mistake 2: Using Too Much Water

Applying too much water or product to seats and carpets can:
- Cause unpleasant odors due to accumulated moisture in the foam
- Create difficult-to-remove stains
- Damage nearby electronic components

Interior cleaning should always be controlled and moderate. Use slightly damp microfiber cloths instead of applying product directly to surfaces.

## Mistake 3: Using Abrasive Cloths or Sponges

Rough sponges or unsuitable cloths can scratch interior plastics and create visible marks on the dashboard and door panels. These scratches are permanent and difficult to correct.

Always use microfiber towels for car detailing — they are safe for all delicate surfaces and do not leave loose fibers.

## Mistake 4: Not Cleaning Contact Areas

The dirtiest areas of the interior are also the most overlooked:
- Steering wheel: accumulates hand grease and bacteria
- Gear shift knob
- Dashboard buttons and controls
- Door handles

These areas require regular cleaning with an appropriate product and a detailing brush for corners and crevices.

## Mistake 5: Ignoring Plastic Protection

After cleaning, many people forget to protect interior plastics. This is especially important in Portugal and Spain, where intense sun exposure degrades plastics quickly.

Interior protection products:
- Prevent discoloration and fading caused by the sun
- Reduce dust accumulation
- Maintain a refreshed look for longer

## Mistake 6: Not Vacuuming Before Cleaning

Applying products to dusty or sandy surfaces can cause microscopic scratches and spread dirt. The correct process always begins by:

1. Vacuuming the entire interior — seats, carpets, console, and doors
2. Removing all loose debris
3. Only then starting cleaning with wet products

## Mistake 7: Cleaning Everything with the Same Product

Each material requires specific care. Using the wrong product can damage finishes, discolor surfaces, or leave residues.

- Plastics and vinyl: mild APC or specific interior cleaner
- Fabric seats: dedicated upholstery cleaner
- Leather: pH-balanced cleaner followed by conditioner
- Glass: alcohol-free automotive glass cleaner for windows with tint film
