Do you usually have a tumbler? Recently, the use of personal tumblers has spread, leading to a positive change in reducing the use of disposable cups and contributing to environmental protection... While tumblers are an effective way to maintain the temperature of beverages and reduce unnecessary waste, there are certain things to keep in mind when using them.

✅ Advantages of using a tumbler

1. Maintaining beverage temperature

Tumblers keep the temperature of your drinks for a long time through their insulation and cooling functions. You can enjoy warm coffee or tea warm, and cold drinks cold.

2. Environmental protection

You can reduce the use of disposable cups and reduce environmental pollution. By using a tumbler, you can reduce the amount of disposable cup waste that is generated daily and participate in environmental protection.

3. Economical

You can reduce the cost of buying disposable cups every day. Tumblers are economical because you can buy them once and use them for a long time.

✅ Cleaning and managing tumblers

1. Cleaning

It is not hygienic to simply rinse your tumbler with water just because it contained liquid. You should separate the lid, rubber packing, etc., and thoroughly clean the inside using detergent and a brush, then rinse it.

2. Drying

If moisture remains inside the tumbler after cleaning, it can increase the risk of bacterial growth. It is necessary to dry it completely after wiping it clean with a cloth.

3. Replacement

If there are stains or odor inside the tumbler even after repeated cleaning, it should be replaced with a new one immediately.

⚠️ Beverages that should not be put in tumblers

1. Dairy products and juices with high sugar content

Milk, soy milk, yogurt, fruit juices, etc., can promote bacterial growth inside the tumbler, leading to odor. If you don't drink it within 2 hours, bacteria growth will intensify. Dairy products can also corrode the tumbler's inner wall if they stick to it.

2. Carbonated drinks

If you put carbonated drinks in a tumbler and close the lid, the internal pressure can build up, causing the lid to pop open and you to get hurt. Be careful not to put any carbonated drinks, such as sparkling water, cola, soda, and carbonated energy drinks, in your tumbler.

3. Hot beverages

If you put hot beverages in a tumbler and close the lid, steam pressure can increase, causing burns when opening the lid. It is safe to let the steam escape for about 1 minute after putting hot water, tea, hot chocolate, etc., in a tumbler, before closing the lid.

4. Alcohol

Ethanol, the main ingredient in alcoholic beverages such as beer, soju, and whiskey, contains acid, which can corrode the stainless steel inner wall if left in for a long time.

5. Soups

Soup broth, fish cake broth, and other types of soup can corrode the inner wall of the tumbler. If you often put soup in your tumbler, it's a good idea to replace it with a new one.
