Hey there! As a glass tumbler supplier, I get a ton of questions from customers about how to keep their glass tumblers in tip - top shape, especially those narrow - mouthed ones. Cleaning the inside of a narrow - mouthed glass tumbler can be a real pain, but don't worry, I've got some tried - and - true methods to share with you.
First off, let's talk about why it's so important to clean these tumblers properly. Narrow - mouthed glass tumblers are great for keeping your drinks fresh and can be really stylish. But because of their design, it's easy for dirt, grime, and bacteria to build up inside. If you don't clean them regularly, you might end up with a funky smell or even an unappetizing taste in your drinks.
One of the simplest ways to start the cleaning process is with warm, soapy water. Grab a mild dish soap and fill your sink or a large bowl with warm water. Stir the soap around until it's nice and sudsy. Then, submerge your narrow - mouthed glass tumbler in the soapy water. Let it soak for about 15 - 20 minutes. This will help loosen up any stuck - on gunk.
While it's soaking, you can look around for a cleaning brush that fits through the narrow opening. You can find some really handy ones at your local hardware or kitchen supply store. These brushes usually have long handles and small, bristly heads that can reach deep into the tumbler. Once the soaking time is up, take the tumbler out of the soapy water and gently scrub the inside with the brush. Pay extra attention to the bottom and the corners where dirt likes to hide.
If you don't have a specialized brush, don't fret! You can make a DIY cleaning tool. Take a chopstick or a long, thin stick and wrap a piece of clean cloth around one end. Secure it with a rubber band. This makeshift tool can work just as well to scrub the inside of the tumbler.
For those stubborn stains that just won't come off with soapy water and a brush, you can try using vinegar. Vinegar is a natural cleaner that can break down tough stains and remove odors. Mix equal parts of white vinegar and water in a container. Pour the mixture into the narrow - mouthed glass tumbler until it's about half - full. Let it sit for an hour or two. The acidic properties of the vinegar will start to eat away at the stains. After that, pour out the vinegar mixture and rinse the tumbler thoroughly with warm water. You might notice a slight vinegar smell at first, but that will go away once the tumbler dries.
Another great option for tough stains is baking soda. Baking soda is a mild abrasive that can help scrub away stains without scratching the glass. Make a paste by mixing baking soda with a little bit of water. The paste should be thick enough to stick to the spoon. Use a spoon to apply the baking soda paste to the inside of the tumbler. Then, use your brush or the DIY cleaning tool to scrub the paste into the stains. Let it sit for a few minutes before rinsing it off with warm water.
Now, if you're dealing with a narrow - mouthed glass tumbler that has a lot of crevices or hard - to - reach areas, you might want to consider using a Rotary Rock Tumbler. These tumblers are designed to agitate small objects and can be used to clean your glass tumbler as well. Just add some cleaning solution, like the vinegar - water mixture or soapy water, along with a few small, smooth stones. The tumbling action will help dislodge dirt and stains from all the nooks and crannies.


Once you've cleaned the inside of the narrow - mouthed glass tumbler, it's important to dry it properly. You can use a clean, lint - free cloth to dry the inside and outside of the tumbler. Make sure to get all the moisture out, especially from the bottom and the inside where water can pool. If you want to be extra careful, you can let the tumbler air - dry upside down on a clean dish rack.
