Streaky car windows usually happen because cleaning product is left on the glass and dries too quickly, or because your towels are pushing around a layer of grease and dirt.
You can prevent streaks from appearing on the windows by parking your car in the garage before cleaning the windows. Also, you can consider cleaning windows when the climate is cool like in the evening when the sun is not shining directly on your head.
To achieve a streak-free shine with Windex, avoid cleaning on hot, sunny days to prevent premature evaporation. Dust first, apply Windex generously, and wipe with a clean, lint-free microfiber cloth or crumpled newspaper, never paper towels. Buff dry immediately.
To get rid of streaks on your windshield, always clean the glass out of direct sunlight using a two-towel method (one to apply the cleaner, one to buff dry). Use vertical strokes on the outside and horizontal strokes on the inside, allowing you to quickly isolate which side any remaining streaks are on.
To easily remove dried, baked-on soap or soap scum from car windows, start by mixing a 1:1 solution of distilled white vinegar and water (or use 70% rubbing alcohol). Spray it onto the glass, let it sit for 1–2 minutes, and wipe it away vigorously with a microfiber cloth.
Pro Tips and Common Mistakes
Ditch the paper towels—they're scratchy and leave fibers behind. Waffle weave microfiber towels are your streak-free, dirt-trapping best friends. Stick with ammonia-free, glass-specific cleaners. They're safe for tints and won't damage your car's interior finishes.

Paper Products and Old Towels
Paper towels and old towels are staples in most home car washing kits. If you're using these items to clean your auto glass, now is the time to stop. Paper towels are dangerous for glass, as the rough texture of the paper towels can leave behind scratches.

Dish soap is expected to effectively remove WD40 stains!
"WD-40 can degrade rubber, such as the rubber seals used around windows and doors. The degradation of these seals can result in air infiltration and thus lower energy efficiency." Using lubricating spray on hinges can increase the risk of attracting dust and dirt, causing them to further stiffen up over time.
Achieve a flawless, streak-free shine by mixing 2 cups of distilled water, 14one-fourth𝟏𝟒 cup of white vinegar, and a 12one-half𝟏𝟐 teaspoon of Dawn dish soap in a spray bottle. Alternatively, use professional ammonia-free cleaners like [Meguiar's Perfect Clarity Glass Cleaner](walmart.com Clarity-Glass-Cleaner-Streak-Free-Pro-Strength-24-Oz/36636772) or Sprayway Glass Cleaner.
Let it sit for 10-20 minutes. The vinegar will help loosen the residue, so you can wipe it away more easily. Bird droppings or other tough grime: pre-soak the area with a vinegar solution and allow it to soften before scrubbing with a damp microfiber cloth.
