How do you clean a decanter?

Cleaning a decanter is trickier than cleaning a regular bottle or wine glass. Its wide base and narrow neck make it impossible to reach the inside with a standard sponge. Nevertheless, a decanter can be cleaned thoroughly, even without special equipment. The right method depends on how dirty the decanter is and how long wine residues have had to dry.

Immediately after use: quick rinse

The easiest way to keep a decanter clean is to rinse it with lukewarm water immediately after use. Fresh wine residues come off easily. Fill the decanter one-third full with lukewarm water, close the opening with your hand, and shake the decanter vigorously back and forth a few times. Pour out the water and repeat two to three times until the water remains clear.

Do not use hot water immediately after use if the decanter is still cold. Too great a temperature difference can cause the glass to crack, especially with thin-walled glass decanters. Lukewarm water is always sufficient to remove fresh wine residues.

Method 1: salt and ice cubes

For stains that don't disappear with water alone, the combination of coarse sea salt and ice cubes is a proven method. Put a generous tablespoon of coarse sea salt into the decanter, add a handful of ice cubes and a splash of cold water. Close the opening with your hand and shake the decanter vigorously back and forth in all directions for a minute.

The salt acts as an abrasive that loosens the stains from the glass. The ice cubes agitate the mixture and ensure the salt reaches the wide base and the side walls. Afterward, rinse thoroughly with lukewarm water until no salt residues are visible or tasted. This method is safe for both regular glass decanters and crystal decanters and leaves no odor or taste.

Method 2: white vinegar or citric acid

Tartar deposits consist partly of acid but also dissolve in acid. White vinegar and citric acid both work well to remove deposits in a decanter. Pour a splash of white vinegar into the decanter and fill with lukewarm water until the decanter is one-third full. Rotate and tilt the decanter regularly so that the vinegar mixture touches all walls. Let it stand for an hour for light deposits, overnight for stubborn deposits.

Citric acid works in the same way. Dissolve a teaspoon of citric acid powder in lukewarm water and pour the mixture into the decanter. Citric acid is odorless and tasteless after proper rinsing, which is an advantage over vinegar if you want to avoid the smell of vinegar. After soaking, always rinse thoroughly several times with clean water.

Method 3: cleaning beads

Decanter cleaning beads are small stainless steel balls that you put into the decanter with water. By shaking and rotating the decanter, the beads scrub the inner wall clean. They also reach areas that are difficult to clean with other methods, such as the transition between the wide base and the narrow neck.

Cleaning beads are reusable and long-lasting. After use, rinse them off and store them dry. They are particularly suitable for regular use if you want to clean the decanter after each use without having to use salt or vinegar every time.

Method 4: effervescent tablets

Effervescent tablets for dental prostheses contain active cleaning agents that also dissolve wine residues and deposits. Put one tablet in the decanter, fill with lukewarm water, and let it effervesce. After half an hour to an hour, rinse the decanter thoroughly. This method works surprisingly well for stubborn deposits that do not completely disappear with salt or vinegar and is little known but effective.

What you should avoid doing

Abrasives and steel wool damage the glass and leave microscopic scratches where new deposits adhere more easily. Strongly scented soap permeates the glass and affects the taste of the next wine. Dishwashers are not recommended for most decanters: high temperatures and aggressive cleaning agents can dull the glass and affect its shape. For thin-walled crystal decanters, the risk of breakage in the dishwasher is also greater due to the vibrations of the program.

Also avoid hot water if the decanter is cold or cold water if the decanter is warm. Thermal shock is one of the most common causes of cracking in glass decanters.

How to dry a decanter without streaks?

After cleaning and rinsing, drying is the next challenge. A decanter with a narrow neck cannot be dried from the inside with a cloth. Water droplets that dry leave lime streaks on the inside that are visible when you hold the decanter up to the light.

The most convenient solution is a drying rack on which you place the decanter upside down. This allows the water to drain and the decanter to air dry without streaks. Mémoire offers a decanter drying rack specifically designed to safely and stably dry decanters upside down. The drying rack fits all common decanters and prevents the decanter from tipping over during drying.

How often should you clean a decanter?

Rinse the decanter immediately after each use with lukewarm water. This is sufficient for regular use if the decanter has not been left with wine residues for too long. A more thorough cleaning with salt and ice cubes or vinegar should be done when you see deposits inside or if the decanter has not been used for a while and has developed a stale odor.

Store a clean, dry decanter upright with the opening facing up to allow for air circulation. Storing it upside down on a rack is also fine, provided the rack is stable enough. More about removing deposits can be found in how to remove wine deposits from a decanter.

Which decanter is easy to clean?

A decanter with a wider neck is easier to clean than a decanter with a very narrow neck. A wider neck allows for a decanter brush or easier insertion of cleaning beads. The shape of the base also plays a role: a flat base is easier to reach with cleaning beads than a base with a complex round shape.
