Choose a spot out of direct sunlight. A shaded area prevents cleaning products from drying too fast. This keeps the seals moist and easier to clean. Avoid parking under trees to stop dirt or sap from falling on the car.
Gather Supplies
Collect all needed items before starting. You will need a soft cloth, mild soap, water, and a small brush. Having everything ready saves time and avoids interruptions. Use gentle cleaners to protect the seals from damage.
Inspect Window Seals
Look closely at the seals for cracks or dirt buildup. Check for signs of wear or damage. Identifying problems early helps prevent leaks and further damage. Clean away loose dirt before applying any cleaner.
Removing Dirt And Debris

Dust Off Loose Particles
