How to Clean Coffee Maker Glass Carafes?

Many people are left with a stain on their glass carafes from the coffee they make in the coffee maker. It is not always easy to remove this stain, and some people may find it necessary to replace it.

A pot of carafe tends to be used in places like restaurants and coffee shops and keeping them clean is an essential part of a cleanup procedure and maintenance. The best solution for cleaning your carafe depends on the stains and what materials the carafe is made of.

This guide will show you how to clean your carafe without damaging or scratching it. 

Cleaning Glass Carafes

Glass carafes are made of glass, which can easily be scratched and pitted. They also have an acid content that can dissolve a sludge that is present at the bottom. Cleaning the carafe is extremely important because it will prevent corrosion and other damage.  

The carafe can be easily cleaned with a soft cloth, which can be rinsed with warm water and dried. However, there are also carafes made of glass that will need more careful cleaning because they may be scratched by abrasive materials like bleach or detergent.

In this process, you can also see any cracks on the glass carafe by using a magnifying glass. 

Cleaning Glass Carafes With Vinegar and Baking Soda

Vinegar contains a cleansing action that removes unwanted substances from the surface of the glass carafe. A solution in which vinegar and baking soda are mixed is very effective in removing the stains. The best way to do this is to soak glass carafe in the solution for an hour or so. 

Some of the best coffee makers have a carafe that is made of break-resistant glass with a plastic cover. However, even the most durable carafes can be damaged by the acidic cleaner solutions used to get rid of the stains if it stays in hot water for a long time. In addition, the frequent cleaning and replacement of this type of carafe will increase its cost and maintenance in the long run. 

If you want to get rid of the discoloration on your glass carafe, you can mix four tablespoons of baking soda and 1 cup of vinegar in a spray bottle (or mix it in a bowl). Then, spray the mixture onto the stained area on the carafe. 

The method to clean glass carafes is simple. However, it is ideal to wear gloves and old clothes when you’re cleaning as the solution can cause skin irritations. 

What Makes Vinegar and Baking Soda So Good?

Vinegar has a cleansing action that removes oils from the surface of the glass carafe. The baking soda, in turn, helps remove dirt particles. In combination, these two items are very effective in removing stains from your glass carafe. 

Cleaning Glass Carafes With Table Salt and Ice Cubes

You can use a mixture of table salt and ice cubes to clean stains from the carafe. The ice cubes should be crushed because they provide an effective abrasive action while table salt is hydrophilic and combines with the ice to clear the spots and stains. However, the salt has a corrosive effect that can be minimized by using cold water. 

Using table salt and ice cubes to clean a thermal carafe is a simple yet effective method. However, it cannot remove tough stains. However, after the process, you should also rinse the thermal carafe well after using this method.

What Makes the Combination of Table Salt and Ice Cubes Strong? 

Table salt and ice cubes form a strong combination of cleaning agents that are powerful enough to remove a stain. The salt helps remove stains through its rubbing process while ice cubes provide a cool effect to the carafe and aids in cleaning. 

Using Scouring Powder

Scouring powder can be used to clean your glass carafe because it is very effective in removing stains. You can mix two tablespoons of scouring powder with one cup of warm water, then soak your glass carafe for at least fifteen minutes. After soaking, rinse off the product in hot water and dry it well with a soft cloth.

Cleaning Glass Carafes With Vinegar and Lime

Another product that can be used for this purpose is a solution made from vinegar and lemon juice. You can use the zest of the lemon to give it a fresher smell. Lemon juice is acidic and anti-bacterial which can remove any stains from your glass carafe with ease. You can also use white vinegar.

The process starts off with dipping a sponge or paper towel in the solution of vinegar and lime. Rub lightly for 15 seconds. Take care that the solution is not used excessively on the carafe as it can get damaged. If you are using a sponge, be sure to wring it out before use. 

The solution should be rinsed off thoroughly with hot water and then dried using paper towels. You should always test the solution for colorfastness as people have claimed about the reappearance of stains. It is also best to avoid white cloth towels because they can leave a light-colored residue on your carafe and may alter the taste with freshly brewed cups of coffee. 

What Makes Vinegar and Lime So Good? 

Vinegar has an affinity for pulling oils from its surface. Lemon or lime juice, on the other hand, is acidic and removes any stains from your glass carafe quite easily. Lemon juice is also anti-bacterial, and it won’t leave any residue behind when you’re finished using it.

Cleaning your glass carafe with lemon juice will leave a fresh, citrus smell on your carafe. White vinegar can also be used for this process. White vinegar is typically used to clean glass carafes because it provides a clear and vivid display of the carafe. It is also easy to use in kitchens because it is non-corrosive. 

When cleaning your glass carafe with vinegar, you should rinse your carafe thoroughly and then dry it by hand to avoid damage.

Cleaning Your Carafe With Vinegar and Citrus Peels

You can also use a mixture of lemon juice, white vinegar and citrus peels. The lemon zest will render a fresh aroma to the carafe while citrus peels would aid in the cleaning process as it is composed of organic compounds and is anti-bacterial in nature. Cleaning your glass carafe with citrus and vinegar is a quick and easy method. However, you must rinse your carafe well after using this method to avoid damage.

What Makes Vinegar and Citrus Peels a Good Combination?

Citrus peel has an affinity for pulling oils from its surface. It is also anti-bacterial, so there is no need to worry about damaging your carafe or leaving behind residue. The citrus peel also contains organic substances that gives the carafe a nice aroma, and alters the flavorful sensation of freshly brewed coffee. Vinegar, on the other hand, will remove stubborn marks from your carafe and leave it sparkling clean.

Cleaning Bunn-Style Coffee Carafes With Bleach

Bleach is a biodegradable liquid chemical that can be disposed after use. It can remove stubborn stains from your carafe and acts as a disinfectant, killing microorganisms like bacteria and fungi. Bleach is safe to use but you should always wear gloves when handling it.

You can use bleach to clean your carafe if you don’t have any other kitchen products on hand. Bleach is a powerful cleaner and will remove stains from your Bunn-style coffee maker, but it can also damage it over time. Bleach can remove organic stains, but it will not work on inorganic stains. 

Furthermore, there are some commercial cleaners that claim to be effective for cleaning Bunn-style coffee carafes. These cleaners contain bleach and water which will remove dirt and impurities effectively. However, bleach has the tendency to leave yellow marks on different surfaces which keeps its use limited. 

What Makes Bleach a Good Cleaning Agent? 

One of the reasons why you’ll see bleach in carafe cleaners is that it can kill microorganisms. This is especially useful for those who drink their coffee black. Bleach kills microorganisms on contact, and it will leave your carafe fresh and clean. Bleach can also ruin your carafe if you use it too often. This is because the bleach will start to evaporate through the porous polycarbonate material and may leave behind a yellow residue on your carafe.

Cleaning Bunn-Style Coffee Carafes With Cleaning Liquids

You can also use wipes, cleaners or sponges if you don’t have one of these examples on hand. This is a simple way to get rid of stubborn stains on any specialty coffee carafe. 

Moreover, cleaning liquids are great for keeping your carafe clear and free of stains. They work by dissolving the grease that has accumulated inside your carafe. Cleaning liquids include cleaner, dish soap and mild detergent. To use them, you should take the following steps:

Step 1: You should fill the carafe with hot water. Hot water will help dissolve the dirt inside your carafe.

Step 2: Add a couple of teaspoons of cleaning liquid to the mixture and stir well. You can use any kind of cleaning liquid that you have on hand, but you should avoid using dish soap if you have hard water in your area because it will leave a residue. Dish soap can also damage the surface of your coffee maker over time. 

Step 3: Rinse your coffee maker thoroughly with hot water and allow it to air-dry. You should test the mixture before using it on your carafe and if it leaves a residue, add another teaspoon or two of liquid.

Choose the Right Cleaner

First, rinse your glass carafe under cold water several times. Then, dry it on low heat using paper towels. Use a product that has anti-bacterial and anti-odor properties so that the stain won’t return. Use one of the following products:

1) A product that has a mildly abrasive action, such as the one made by Cascade.

2) A product that has anti-odor properties such as Windex.

3) A mixture of vinegar and lemon juice, a product called Spot Shot. 

4) Another product is called Glass & Surface Cleaner. It is used to clean without damaging the carafe. 

The right cleaner can help get the stain out, but it may also scratch the surface of the carafe. It’s important not to use too much cleaning agent because you may damage this carafe’s clear plastic outer shell.
