Shopping guide

Don’t let glass grime get so far that you only see islands of dust and fingerprints through your windows. With this guide to buying the best glass cleaner, you will be able to choose the most suitable one so that cleaning the glass in your home can be a simple and frequent task that keeps surfaces impeccable and shiny all the time. 


To start the evaluation of aspects that will define your purchase, you must start the comparison of window cleaners with the four types of presentation formats of this product. At the time of purchase, you can find it in liquid form, foam, as pills or wipes. 

Liquid glass cleaner is one of the most familiar formats. However, it also offers variations within its same type. You should look at the description of how to apply it and you will know if it is ready to be used or if it is concentrated and has to be diluted first. 

In the same way, within the forms that require previous preparations, there are effervescent tablets. These are nothing more than solid concentrated detergent that will only need water to dilute. They do not take up storage space and only take a few seconds to dissolve. 

Foam window cleaners usually come in an aerosol form. When activated, an extra strong foamy substance is produced that does not drip and helps to remove the most difficult deposits. Although today there is a production of CFC-free aerosols, care must always be taken that it is a product contained under extreme pressure. 

Finally, glass cleaning wipes are a very convenient option for quick touch-ups. There are even some that work perfectly for cleaning the lenses of glasses. If you take care to close your packaging very well, they will not dry as quickly. 


Another important characteristic to consider is the ingredients or active principles of its composition. Not only do they influence how much the window cleaner costs, but they must be taken into account depending on how allergic you are or want to take care of the environment. 

From there, those who use chemical products or compounds as a base for both cleaning and flavoring and those who opt for vinegar or other natural elements. Opinions differ as to their effectiveness, so it will be a matter of weighing the pros and cons of each formula. 

Ammonia is one of the most used ingredients for its power to remove dirt and odors, as well as its rapid evaporation. However, its possible incidence in respiratory or allergic skin reactions is undeniable. 

For their part, alcohol and glycol ethers are also very effective against grease stains and germs. To avoid eye irritation or possible poisoning with these ingredients, ensure proper ventilation and use. 

Although there are those who say that its effectiveness is not comparable to that of chemical formulas, the use of eco-surfactants, white vinegar and plants such as eucalyptus, pine and mint in natural glass cleaners can achieve cleaning with a very good smell and free of allergies.. Even its containers can be biodegradable made with vegetable ingredients.


Another aspect that you cannot let surprise you is the price of the glass cleaner. The variation in costs is quite wide and we will explain the reasons for you to take them into account at the time of your choice. The first thing that influences is the amount, especially when you want to buy it in liquid form.

Being clear on this will avoid frustrations about how much you’re buying and what price you’re paying. For example, a liter of glass cleaner you choose can mean literally a liter to use or it could turn into many more liters of use if it is concentrated and has to be diluted. 

On the other hand, you may think that a liter that is already diluted is cheaper, but it will last less time than a concentrated one that yields preparation after preparation. Similarly, the value varies when choosing between containers with spray guns or not and containing 500 ml, 1, 2, 5 or up to 20 liters. 

Likewise, the use for which the window cleaner has been formulated is decisive. Products are offered for various purposes with a multi-use function, only for mirrors and windows or those intended as windshield wipers for the best visibility when driving.

Specialized glass cleaners are usually a little more expensive, as are the ecological ones, and it will be up to you to want to make the investment. In addition to taking care of the environment, the latter can prevent the damage that ammonia and alcohol could cause in televisions, monitors and other electronic devices.

Frequently asked questions


Q1: How to use the glass cleaner? 

Glass cleaner is a detergent that, if not used correctly, could leave soapy stains and marks in its wake. When too much is applied, the liquid or foam can drip and leave streaks, so only spray or pour on the cloth as necessary. After you rub it in and remove the dirt, you can buff it up with another dry cloth. 

Try as much as possible that the cloth you use is microfiber and avoid paper towels, as they could leave lint. Squeegees are also ideal for removing glass cleaner. Another tip is not to clean at times when the sun shines directly on the windows, as this could cause the glass to dry out very quickly and leave stains. 

Q2: How to make a homemade glass cleaner? 

One of the most popular and simple homemade recipes to leave your windows impeccable is by combining water and white vinegar in equal parts. Three drops of dishwashing liquid are added to this solution and the mixture is ready to start grease and germs. 

There are those who, to reinforce the cleaning effect of vinegar, prefer to mix it with the power of lemon. Two cups of water, two tablespoons of vinegar and ten drops of lemon essential oil create a great formula that, in addition to being effective, will have a pleasant citrus aroma. 

Q3: What happens if you drink glass cleaner?

If keeping the window cleaner out of the reach of children did not work and you suspect or are sure that the child drank it, it is best to call your treating doctor for immediate instructions or take him to the nearest health center.

If it is an ammonia or alcohol-based product, you should not try to induce vomiting or give the child anything to eat or drink. 

Q4: How does the water repellent glass cleaner work? 

The 2-in-1 products that are window cleaner and rain repellent make up one of the best options when you know that you are going to drive on a rainy day, likely to hail or snow. The action of the repellent together with the breeze causes the water or hail to slip and not adhere to the glass. They are widely recommended when you do not want to take risks due to poor visibility in a very humid climate.

Q5: Which is better, alcohol-based or vinegar-based glass cleaner? 

This decision is largely based on sensitivity to respiratory reactions. Alcohol is an effective cleaner of dirt and grease, but without proper ventilation it could affect breathing or irritate the eyes. Also, you have to be very careful to keep it away from small children. 

For its part, vinegar is not an irritant or an allergy agent. Although good at cutting through grease and killing germs, the action of a window cleaner with vinegar as an active ingredient is not considered as powerful as an alcohol-based one.
