How we tested


Our price per ounce was estimated using popular packaging sold on Amazon at the time of publication in order to compare our items equitably.

Costs for ingredients utilized in our homemade glass cleaner were also taken into account when calculating the total cost of the product. After that, we computed the price depending on how much of the product we actually utilized.

Our basic, home-cooked food Your Best Digs cleaner is the cheapest approach to clean glass surfaces (per ounce) despite the fact that it is more expensive, both in terms of time and money, in the beginning.

The cheapest commercial product is Windex, however buying large refill containers, like the 128-ounce Windex offering on, usually decreases the price regardless of the brand. Plant-based components make Seventh Generation the most expensive.


The interior and outside of the windows must be cleaned at the same time. A living room window was recreated as it was cleaned outside by smearing mud and debris and allowing it to dry. We then rubbed an olive oil-coated hand on the window to create greasy palm prints. After a few minutes of using each product, we finished cleaning the windows with the same method.

The products from Windex and Zep Streak-Free Glass Cleaner were superior in terms of both eliminating the chemicals and providing a streak-free finish. In order to remove the most stubborn spots, both of the glass cleaners clung to the pane without running. The absence of any streaks or fog made the windows appear dazzlingly bright.

Both Weiman Glass Cleaner and Stoner Invisible Glass Cleaner aerosols performed admirably in our tests. They were equally effective. Using a foamy spray, we were able to remove even the most stubborn messes. As a result, they left the windows a little smudgey. The streaks didn’t bother me or stand out much, although they could be seen from certain angles. There were also noticeable streaks left behind by the Glass Plus Glass Cleaner Trigger.

Our homemade cleaner and the Seventh Generation Surface Cleaner had a harder time getting rid of the smudges, especially the oily handprints. Even after the prints were erased, oil residue remained on the window, causing streaks that could be seen. Windows were still not as clean as they were when we tried Windex and Zep, even after extensive polishing.


If windows have the most glass surface area in the house, it’s likely that mirrors are right behind them. You can use this cleaner in different circumstances even though this is a review of window cleaning services technically. Particularly bathroom mirrors suffer from a great deal of abuse. Every day, mirrors get smeared by sprays, gels, creams, lotions, and fingerprints.

This was done by spreading toothpaste on the bathroom mirror with a fingertip in order to mimic real-world cleaning scenarios. We then applied a dime-sized amount of hair gel in the same way. Using our glass-cleaning process, we removed the smudges after 15 minutes.

Stains may be easily cleaned with several solutions, but Windex simply required moderate pressure and a minimum amount of buffing to be entirely erased. When the mirror had been cleaned using Windex solution, it looked its finest.

Glass Plus worked well, but we had to work harder and use more pressure to get all of the toothpaste out of the glass. In addition, there were a few splotches of paint on the surface.

There were noticeable streaks left behind by Weiman Glass Cleaner and Zep Streak-Free Glass Cleaner depending on the angle and distance from the glass.

The imperfections were quickly eradicated with our homemade treatment, but the mirror appeared foggy and dull. When compared to the commercially available alternatives, there was a clear distinction.

Seventh Generation did an excellent job of removing the problematic compounds, although it left behind a few stray bits of dust. These barely perceptible flaws could not be removed even after extensive buffing.

However, it took several applications of Stoner cleanser to remove the toothpaste completely from the hair gel. Second and third applications may be necessary, according to the can’s directions, to loosen and absorb trace deposits. There was still some residue even after the third application.

Exploding chili in the microwave

When it came time to put our top candidates to the test, we wanted to see how they fared when faced with a scenario that was both nasty and all-too-frequent: a microwave explosion. All of the inside surfaces of our microwave are made of plastic except for the spinning glass tray.

When we microwaved a glass bowl of chili for six minutes on high, what came out was a sloppy mess that everyone has seen before. Once the chili had dried for 30 minutes after each explosion, we used each glass cleaner to try to restore the microwave’s luster.

Best Window Cleaners - Best Window Cleaning Products

With Stoner’s Invisible Glass and Weiman’s Glass Cleaner, the two aerosol products, we were able to remove the chili considerably more effectively than our other contenders. Even the driest parts of our lunch were easily removed from the inside of the door.

Windex and Zep Commercial Glass Cleaner were the most effective liquid sprays. We were able to eliminate all traces of the chili, even though it took a little more effort and attention.

In the chili test, we found our homemade cleaner, Glass Plus, and Seventh Generation to be let down. When it came time to try and remove the caked filth, neither Glass Plus nor Seventh Generation were adequate to the task. A lot of washing and multiple spraying over the same areas were required for the DIY remedy to work, but it eventually worked.

Glass cleaners may not be designed to perform these tasks, but it’s wonderful to know what they’re capable of. Even if we use another product to clean the windows around the workplace, we’ll have our cans of Stoner and Weiman on hand just in case.


There are several factors to consider when it comes to the smell of these cleaning products. The fragrance is a crucial and immediately obvious component when using airborne sprays to clean windows and mirrors.

Most of these cleaners have a bad odor, ranging from somewhat unpleasant (Stoner Invisible Glass) to downright noxious (Stoner Glass Cleaner) (Zep Streak-Free Cleaner). I found Zep and Windex to be the worst ammonia-based cleaners. Ammonia’s pungent odor can be nearly unbearable to breathe in. The experience of utilizing the spray is hampered by the fact that the aroma doesn’t last long.

Our own blend of vinegar, cornstarch, and essential oil was the most enticing. In our 20-ounce spray bottle, we used just 10 drops of highly concentrated peppermint essential oil, which made a huge difference in the user experience.

When you make your own cleaner, you get to choose the scent you choose. Tea tree, rosemary, lemongrass, and dozens of other smells are among the essential oils available.

The aroma of Seventh Generation is difficult to detect. If the scent of your favorite essential oil doesn’t make you smile, this won’t either, but neither will many of the other goods.

When you shouldn’t use glass/window cleaner

Using glass cleaner to clean eyeglasses is another typical mistake. Even though the word “glass” is in the name, eyeglasses have a coating that is specific to the prescription and so assures clear sight. A mild soap and warm water are ideal.

How to clean glass

  1. The nozzle should be six inches away from the surface.
  2. Spray the glass immediately.
  3. Spray in six-inch-wide horizontal rows. This will help to ensure that the sprays cover the entire surface of the window.
  4. Wipe each row from left to right using a microfiber cloth, gently to moderately pressing down on the towel.
  5. If any liquid remains in the glass after the second pass, apply additional pressure and move from the rim to the top of the glass.
  6. Using a new, clean, dry microfiber towel, vigorously polish the glass to remove any remaining blemishes.

Other uses for window/glass cleaners

  • Kitchen equipment have a variety of surfaces.
  • Doorknobs
  • Bathtubs
  • Ink-free whiteboards
  • Fabric
  • Carpet
  • Jewelry

The majority of glass and window cleaners are safe to use on surfaces other than glass, such as granite and marble. In addition to mirrors, kitchen gadgets like blenders and coffee makers can be cleaned with the same materials that are used to remove oily smudges. By using a glass cleaner, even stains on fabric or carpet can be broken up and removed with minimal effort.

Glass cleaners may also do an excellent job of cleaning jewelry. A small amount of the solution can truly bring out the glimmer and brilliance in sterling silver and diamonds in particular.

Insect repellent is the most intriguing use of glass cleaner. To keep them away from a certain location, place a small bowl of glass cleaner on the counter. Even a bee sting can be alleviated with a modest amount of lotion applied to the skin.

How to make DIY window cleaner

Because we needed an all-natural substitute, we ruled out recipes that called for ammonia in our search. Also, we didn’t buy or dilute store-bought cleaning solutions like dishwashing liquid or other produced soaps.

We experimented with a variety of combinations of the most popular elements to see what would work best. Crunchy Betty, who conducted similar testing with several natural substances and found that warm water, white vinegar, and cornstarch were the most effective, so we decided to follow her lead.

Ingredients in the Crunchy Betty DIY Solution

Finally, we wanted to incorporate essential oils into our DIY glass cleaner. Essential oils are a favorite of ours because of their clean, long-lasting scent. (For more details, see our article on essential oil diffusers.) Essential oils, like cornstarch, also inhibit hydrogen atoms in water molecules from joining together, which helps avoid streaking.

Seventh Generation Free & Clear Glass & Surface Cleaner is an option for those who don’t have the time to make their own solution but still want a more natural product.

Important features to consider


A wide range of chemicals and compounds are used by window cleaner manufacturers to generate their solutions. This information will help you make an informed judgment about the substance’s effectiveness and potential health consequences. Because glass surfaces, such as windows and mirrors, are constantly cleaned and touched, it is critical to know exactly what ingredients are contained in the cleaning chemicals used on them.

Many of these substances have a lot of information available. It can be confusing, inconsistent, alarmist, and difficult to understand at times. We strongly advise anyone with an interest in learning more to do so. Below you’ll find a quick rundown on some of the most common chemicals in window cleaners.


When it comes to chemicals in America, ammonia is one of the most commonly used. Most commonly, it’s used in fertilizer, insecticides, cleansers, plastics, and water purification goods. Zep Streak-Free Glass Cleaner contains it, as does Windex. The other five goods that we examined did not contain any ammonia.

Because it evaporates quickly and prevents stains, ammonia is commonly found in household cleaners. Many people believe that the risks to health from this substance are negligible because it evaporates so quickly. However, ammonia is exceedingly hazardous and can induce respiratory and skin irritation, as well as asthmatic and allergic reactions, if overexposed to high concentrations. If ammonia is accidentally inhaled or ingested, you should seek immediate medical attention.

Aside from its flammability, ammonia has the potential to cause a deadly chemical reaction when it’s used in combination with bleach. Chloramines are poisonous gasses formed when bleach and ammonia are combined together in a closed container. Sickness and fluid buildup in the lungs are possible side effects of exposure to these chloramines. Both of these compounds should be kept out of the reach of children and out of reach of each other.

Glycol ethers

Water-based paint and cleaning products often contain a common type of solvent known as glycol ether. In addition to causing a sore throat when inhaled, glycol ethers can contribute to narcosis, pulmonary edema, and severe liver and kidney damage when inhaled in significant quantities, according to the EPA. 2-Butoxyethanol (found in Weiman Glass Cleaner and Zep Streak-Free Glass Cleaner) and propylene glycol (found in Windex) are just a few of the chemicals that fall within the glycol ether umbrella (an ingredient in Glass Plus Glass Cleaner Trigger).

It is a group of solvents that can be found in a variety of cleaning products, degreasers, and paints. When inhaled, glycol ethers can cause narcosis, edema of the lungs, and serious liver and kidney damage, according to the Environmental Protection Agency (EPA). Weiman and Zep glass cleaners have 2-Butoxyethanol as an ingredient, as does Windex, while Zep Streak-Free glass cleaners contain propylene glycol as an ingredient (an ingredient in Glass Plus Glass Cleaner Trigger).

The endocrine system is also disrupted by phthalates, which has a negative impact on male sperm count and reproductive health. For the same reason that corporations aren’t obligated to declare the ingredients of their fragrances, it’s impossible to know which ones include phthalates and in what amounts.

Other ingredients

Our top six items contain a wide variety of additional components. It’s safe to say that some people have expressed greater anxiety than others. The ingredients of these items are not needed to be listed on the bottle, and most manufacturers do not comply with this rule. There is no certainty that internet ingredient lists provided by some companies are complete.

State and federal initiatives have recently been made to demand the direct disclosure of all constituents in home chemicals on the package, with mixed results. We advise you to conduct some of your own research into these and other things you frequently use at home in order to make informed comparisons and prudent purchases.

No matter what product you buy, there are a few general safety principles you should follow to keep yourself and your family as safe as possible from potentially harmful substances.

Rules for Safe Cleaning

  1. Maximize the amount of fresh air being drawn in. Open the windows and turn on the air conditioning.
  2. Dishware, kitchen utensils, and children’s toys should never be cleaned using glass cleaners.
  3. Keep a safe distance from open flames and other sources of high temperature.
  4. Keep it out of the hands of youngsters at all times.
  5. Contact a doctor if you notice any unusual effects while using this medication.

Spray bottles and aerosol cans are the two delivery options for the liquids we examined. However, both Stoner and Weiman are selling aerosols, but none contains CFSs, which have been shown to degrade the ozone layer over time.

These cans are made of metal, and their contents are subjected to a lot of pressure. The cans can be deadly if they are exposed to high temperatures or punctured by accident.

When sprayed on a surface, aerosols produce more foam than other methods. More comprehensive coverage and saturation as well as the breakdown of hard-to remove fats and silt are achieved by using foaming agents such as this one

Spray bottles are used to apply all of the other products, including the one we made. Child-resistant nozzles are a standard feature of the Seventh Generation Free & Clear Glass and Surface Cleaner. Since children are more likely to accidentally consume Seventh Generation products than other brands, this safety element is especially welcome.

Tips to help avoid streaks on your window

Streaks on windows are one of the most difficult aspects of glass cleaning. But if you follow these steps, you can finally get rid of those pesky annoyances:

  • If the filth on the window is too tough to remove with a vinegar solution, use dishwashing soap on the surface first. So that the vinegar solution can do its job properly, you should first remove any persistent stains with a stiff brush.
  • Vinegar on its own is quite acidic, so always dilute it before using it. You may make a safe mixture that is mild and effective on glass and other household surfaces by diluting it with equal parts water. Streak-free outcomes are ensured this way!
  • To avoid streaks, make sure the glass is totally dry before attempting another cleaning. The best way to remove streaks from a window is to wipe it down with a squeegee, a paper towel, or a microfiber cloth.
