This comprehensive guide offers step-by-step instructions on how to clean car door sills and keep them in top condition.

I. Preparation before Cleaning

The first step in cleaning car door sills is gathering all the essential supplies.

Supplies needed:

  • Vacuum Cleaner
  • Bucket
  • Warm Water
  • Mild Soap/Detergent
  • Cleaning Brushes (Soft & Hard)
  • Microfiber Towels
  • Car Wax/Sealant

II. Vacuuming the Debris

Before you deep dive into cleaning, it’s best to vacuum away the loose dust and debris from the door sills. Use a handheld vacuum cleaner to do a preliminary clean-up.

III. Mixing the Cleaning Solution

In a bucket, mix warm water and a few drops of mild detergent or car wash soap. Ensure the soap is adequately dissolved in the water before proceeding.

IV. Cleaning the Door Sills

Dip a soft cleaning brush into the soapy water, then gently scrub the door sill surface, focusing on stained spots. Always be cautious to avoid scrubbing too hard, as it might scratch the paint.

V. Rinsing and Drying

After giving the door sills a thorough scrubbing, rinse them with clean water, ensuring not a trace of soap is left. Using a microfiber towel, pat them dry.

VI. Stubborn Stains and Grime

For stubborn stains or grime, use a hard brush for more intensive scrubbing. If this doesn’t work, a specialized car stain remover can serve as a last resort.

VII. Waxing

Almost done! Now, protect your car door sills by applying car wax or sealant. Use a clean microfiber towel, apply the product, then polish the door sills to give them a shiny new look.

VIII. Regular Maintenance

Cleaning your car door sills should be part of your regular car maintenance schedule, say once every fortnight, or as needed. Regular cleaning not only maintains the aesthetic appeal of your car but also extends its lifespan.
