Why Should I Use Car Window Cleaner?
Car window cleaner is specifically formulated for use on, you guessed it, all the glass for your car. It won’t scratch or otherwise damage your windows. It also won’t streak (well, ideally, at least).
Car window cleaner is for cleaning windshields (obviously), the rearview mirror and the side mirrors. It’s not ideal for cleaning headlights; there’s a different cleaner for that, as well as headlight restoration kits. Never use window cleaner on your car’s paint, upholstery or anything besides windows and mirrors.
Along these same lines, only use car window cleaner on your car’s windows and mirrors. Never use car wash soap, dish soap, car seat cleaners, or household cleaners. They’ll likely streak or cloud the glass – and can even scratch it severely!
Household glass cleaner is an exception. It can be safe to use on your car’s glass. However, household glass cleaners (like Windex) often contain ammonia, which may or may not be what you want.
Should Window Cleaner Contain Ammonia?
Glass cleaners either have ammonia or are ammonia-free. Each has advantages and disadvantages.
Ammonia-based cleaners are the toughest type. They’ll remove built-up, caked-on grime. However, they can’t be used on all types of windows.
Never use an ammonia glass cleaner on tinted windows. It’ll dull the tint and, if used often enough, slowly remove it altogether.
Also, ammonia cleaners can dry out rubber, plastic, leather, and vinyl. Even though you won’t be spraying cleaner on any of those materials directly, be careful with overspray.
Be careful when using ammonia inside your vehicle. Ammonia fumes can burn your ears, nose, and throat even at low levels. At high levels, especially in a closed area like a car, exposure to ammonia fumes can cause respiratory distress and other serious problems.
Why is Window Cleaner Different from Other Types of Cleaners?
You’ve read all about the types of products you shouldn’t use on your windows. But what makes car window cleaner so special, anyway? It has three important features which differentiate it from other cleaners:
Many cleaners, including those used on your car’s paint, can have a coarse consistency which helps remove dirt and grime. Now, this doesn’t mean the cleaners feel like sand. It’s “coarse” on a teeny-tiny, microscopic level which won’t damage the car’s paint, upholstery, etc.
But glass is often far more sensitive to damage. Cleaners which are gentle enough for other parts of your car can scratch up your windshields and mirrors. Car window cleaners are specially formulated to avoid scratching glass even with hard scrubbing.
Long, blurry streaks can be caused by a poor-quality cleaner, lack of proper towel technique, or both. Water is probably the streakiest liquid you can use. Car window cleaner is formulated to avoid streaks (and we’ll go over cleaning techniques which help avoid streaks in just a few).
Haze is that cloudy fog which can build up on your windows. It’s often subtle but widespread. Haze is usually caused by using the wrong type of cleaner on glass. However, it’s not always intentional. Overspray from dashboard cleaners like Armor All is a common cause of front windshield haze.
Car window cleaner doesn’t only help prevent haze, but it can also remove existing haze build-up.
How Do I Clean My Car Windows?
Keeping your car windows clean involves using:
- The right cleaner
- The right techniques
We’ve covered how to select the right cleaner above. Let’s now take a look at the most efficient and effective way to clean your car windows inside and out:
Gather Your Cleaning Supplies
Here’s what you need:
Car Window Cleaner
You’ve already got this covered. Let us know your favorite in the comments.
Plastic is best. Metal buckets can corrode and release tiny bits of metal into the water. Note that you might need two buckets:
A clean water bucket
A water bucket to mix concentrated cleaner
Spray cleaners are usually the easier option, but concentrated cleaners can be an economical choice. If using a concentrated cleaner, be sure to follow the dilution instructions carefully! A formula which is too strong can damage your windows or stain your interior or exterior.
When cleaning your windows, you have two options: mitts or cloths. While mitts will work, cloths are usually considered the better choice. Windshields have tiny corners, slopes, and angles. A cloth allows you more flexibility for the sometimes-awkward surface areas.
Only use microfiber cloths. Microfiber is a man-made fiber known for its strength and small, dense weave. It captures germs, uses water and chemicals effectively, and won’t scratch glass.
At the very least, you’ll want two cloths. Use one to apply the spray then the other to wipe it away. For the best results, use a pair of clean cloths for every section of your car (front windshield, right side, left side, rear windshield). Using clean cloths helps prevent cross-contamination, streaks, and scratches.
You’ve gathered up your supplies. Now it’s time to clean your windows!
Park Your Car in the Shade
Keep your windows out of direct sunlight when washing them. Cars absorb heat fast. The cleaning agent will dry too quickly if the car is hot. Wait until your car is cool to the touch before cleaning the windows.
Generally, warmer days are ideal for cleaning your windshield. Mild, warm air helps the spray evaporate after a reasonable time. Cold temperatures are unlikely to freeze the spray, but it can increase the likelihood of streaks.
You don’t have to wash your entire car before cleaning the windows. However, if you’re doing both at the same time, wash your car first. Cleaning the windows should be the last step in the car wash. You’ll likely smudge and streak up your windows when washing the paint. Washing your windows last removes any car wash soap.
Before using the spray, use a clean cloth to wipe away any dry debris such as leaves or pollen which may have gathered on your windshield.
Clean the Interior First
Truthfully, this isn’t the most important car care rule in the world, but cleaning the interior windows before the exterior is usually the best order.
When you clean the exterior windows, your car doors are closed. Spray can’t enter your car. But when cleaning the interior, your doors should be open, to avoid excessive exposure to fumes. However, with the doors open, spray can splatter out onto the top of the exterior windshields.
Sit in the passenger seat to clean the inside front windshield. Otherwise, you have to work around the steering wheel.
Clean the Glass
When cleaning interior windows, spray the cleaner directly onto a cloth. Generally, you want to dampen the rag but not oversaturate it.
When cleaning exterior windows, spray the cleaner directly onto the glass. You can apply spray far more liberally outside as any excess will evaporate. However, avoid spraying the cleaner onto the car’s paint (although minor overspray usually isn’t harmful).
Place the towel in the back of your hand. It allows you to apply steady pressure to help prevent streaks naturally. It might feel a bit weird at first – and you can still hold the cloth normally when you want – but the backhand method cleans large areas quickly.
Clean in different directions. For example, wipe the interior glass up and down and wipe the exterior glass side to side. The cross-section strategy makes smudges and missed spots easy to see.
Give each window at least two passes. First, wipe the glass with spray using one cloth. Then use a second, clean cloth to wipe up any cleaner.
Remember: there’s no need to rush. For some reason, people often think they need to clean glass as fast as possible. But rushing the job increases the chances of streaks.
Clean the Front and Rear Windows
Their unique shape and large size make the front and rear windshields usually the hardest to clean. Don’t spray too much cleanser at one time. You’ll end up racing to wipe it all up before it evaporates. Instead, divide your windshield into four and clean it one quadrant at a time.
Clean the Tops of the Windows
Almost nobody cleans the tops of their side windows – but they should! If you’ve never done this before, the amount of gunk you remove can be substantial.
Roll your side windows down. Spray the top of the window with cleaner then wipe with your clean cloth. Naturally, dirt will likely run down the sides of the window, so clean the top part first.
Roll the window up and then back down. It’ll likely pick up dirt from inside the frame. You can repeat this a few times if the window top continues to be dirty.
When you’ve finished cleaning the side windows, finish up by spraying and wiping your side mirrors. Clean every part of the mirror. If you have an electronic mirror, turn your car on and use the inside controls to adjust the mirror. Moving it manually is usually fine, but there can be a slight risk of damage.
Clean the Wiper Blades
Don’t forget about your wiper blades. They can be cleaned with window cleaner. Spray some cleaner onto the wipers then run a clean cloth down the length of the blade.
Buildup on your wipers can cause streaks. Plus, it can wear down the rubber on the blades. After cleaning, apply a wiper treatment to help keep the blades in great condition.
How Do I Remove Dead Bugs?
Bug guts are one of the most common and stubborn types of grime. If regular cleaning can’t remove dried-on bug splatter, there are a few tricks you can try.
First, soak the bug in cleaner. Then soak a cloth in cleaner. Press the cloth against the stain for a minute or two.
If that doesn’t loosen the bug, try sprinkling a bit of baking soda. After letting it sit for a minute or so, try to remove the stain with your cloth. Repeat as necessary.
Never use a removal method involving extreme temperatures. You can find “advice” on the internet explaining how fire or ice can remove stubborn stains from your windshield. However, these methods are far more likely to damage the glass than help keep it clean.
How Do I Remove Hard Water Buildup?
Hard water buildup is another common problem. Hard water is water with a large number of minerals such as calcium, lime, and magnesium. Also called limescale, hard water spots are the crusty buildup left behind when hard water dries.
Hard water can fall from the ground or spray from your garden hose. Some areas are more susceptible to it than others. Removing hard water buildup typically requires an acidic cleaner. Look for cleaners with phosphoric, sulfuric and hydrochloric acid. Keep in mind these cleaners are toxic so you’ll want to work in an open area while wearing gloves and eye protection.
How Often Should I Clean My Windshield?
Windshields can be deceptively dirty. Road grime builds up slowly over time, which makes it hard to notice. You might be driving around with a filthy windshield and not even realize it.
Generally, you want to clean your car and windshield every two weeks or so. Keeping your windows clean improves visibility, which improves your overall safety on the road.
However, avoid cleaning your windshield with the squeegees at your local gas station. They’re used constantly all day long. Both the squeegee and water are normally filled with dirt, rocks, and grime. Cleaning your windshield at home, with your own gear, delivers the best results.
Aside from regular windshield cleanings, you’ll also want to clean your windshield before any road trips or other long rides. Bring along cleaning spray and rags so you can keep all the windows clean without having to use the gear at the gas station.
It’s tempting to just rinse your windows off with car soap and consider them clean. But for the best results, you want to only use car window cleaner. It’s specially formulated for maximum visibility. Plus, window cleaner helps prevent streaks and haze.
