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 a 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 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 a 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.
