Driving with dirty car windows is not only unsightly, but also dangerous. It may impair your ability to see, especially during sunny days and at night. That’s why it’s essential to keep your car’s windows clean and clear of debris.
But it can be confusing to know which cleaning method is best with so many options available. In this blog, we’ll share some of the best automotive products to use, as well as some tips and tricks to make the job easier and more effective.

Why clean car windows are essential
Having clean car windows is essential for many reasons, including health and safety. Firstly, dirt and grime on the windows can reflect sunlight and glare, making it difficult to see while driving. This is why cleaning your windows is important for improving your visibility on the road.
Secondly, having clean car windows can help prevent fogging, which usually happens when moisture builds up on the glass. Foggy windows can be a serious safety hazard because they can impair your vision while driving, increasing your chances of getting into an accident or injuring someone.
Thirdly, they can improve the overall look of your vehicle. A car with dirty, streaky windows can appear unkempt and neglected, whereas one with clean windows looks well-maintained and cared for.

Products to use
There are many car cleaning products available for cleaning car windows. Some people prefer to use traditional glass cleaners, while others use more specialised products designed specifically for car windows. Below are some of the most common products used:
Glass cleaner
Glass cleaners are one of the most popular products for cleaning car windows. When choosing one, look for a glass cleaner that is eco-friendly and ammonia-free, as ammonia is known to damage the interior of your car as well as create unpleasant odours.
Waterless car wash
A waterless car wash is another popular option for cleaning cars without using water. These products typically come in a spray bottle and already contain a cleaning solution designed to lift dirt and grime from the surface of your car.
Clay bar
A clay bar is a type of detailing product used to remove contaminants from the surface of your vehicle. It can help remove stubborn dirt and grime and is safe to use on car windows. Simply spray the window with matching lubricant and rub the clay bar over the surface to use it on your car’s windows and windscreen.

Step-by-step guide
Below are step-by-step instructions for achieving crystal-clear windows:
- Begin by washing your car with a car wash or shampoo. This will help to remove any loose dirt and grime from the surface of your car, including windows and windshield.
- Use a microfibre cloth to wipe off any excess water from your car to prevent water streaks and allow it to air dry.
- Spray the cleaning solution (or lubricant if you’re using a clay bar) onto the window of your car. Be sure to apply it evenly.
- Use a clean, lint-free cloth to wipe away the cleaner. Start at the top of the window and work your way down in a circular motion. Apply the same technique when using a clay bar, but with light pressure.
- Flip the cloth over and use the dry side to buff the window. This will help to remove any remaining streaks.
- Repeat steps 3-5 on the other windows and windscreen of your car. If you’re using a clay bar, you’ll need to rinse it to remove the lubricant as well as dirt and contaminants.
Common mistakes to avoid
Even though washing car windows and windscreens may seem like a straightforward task, many car owners continue to make the same mistakes. Here are some of them, along with a few tips:
- Using the wrong cleaning product: This may damage your car’s windows, especially if it contains ammonia. It’s always a good idea to choose products that are designed for cars or that are safe for use on car windows.
- Using too much cleaning solution or water: It can leave streaks and make it difficult to achieve a clear, streak-free finish. Water can also seep through window seal gaps, leading to mould growth over time.
- Using a dirty cloth to clean car windows can leave dirt and grime behind. Therefore, it’s always better to use a clean, lint-free cloth to achieve a streak-free finish. Also, consider using rain-repellent products that can help to prevent water droplets from sticking to your window surfaces, making them easier to clean.
- Avoid cleaning on sunny days because the cleaning solution will evaporate too quickly, leaving streaks and marks on the window.
- Not cleaning your windows regularly. This is important to prevent dirt and grime from building up on the surface of your car windows and body.
All in all, keeping your car’s windows clean is essential for maintaining its appearance and performance, as well as ensuring safe driving. By following the steps outlined in this blog and avoiding common blunders, you can keep your car looking its best.
