A glass coffee mug can be an attractive addition to any kitchen or coffee table, but over time, it can become stained and dirty, detracting from its beauty and usability. 

Properly cleaning your glass coffee mug is essential to keeping it looking its best and ensuring that your coffee always tastes great. 

In this article, we will cover the steps involved in cleaning a glass coffee mug, including the tools and materials needed and tips for keeping your mug in good condition for years to come.

Tools and Materials Needed

Before you begin cleaning your glass coffee mug, you will need to gather a few essential tools and materials:

  • Dish soap: Choose a mild dish soap that is free from harsh chemicals and fragrances. Look for a product that is specifically designed for cleaning glassware, as these will be gentle on your mug and won’t leave any residue or streaks behind.
  • Warm water: You will need a supply of warm water to help loosen any dirt or stains that may be present on your mug. The water should be hot enough to be effective but not so hot that it damages the glass.
  • Sponge or brush: A soft sponge or brush can be used to scrub the inside and outside of your mug. Choose a tool that is gentle enough to avoid scratching the glass but firm enough to remove any stubborn stains or residue.
  • Baking soda: Baking soda is a natural cleaning agent that can be used to remove tough stains and odors from your mug. It is gentle on glass and won’t scratch or damage it.
  • Vinegar: White vinegar can be used to remove mineral deposits and hard water stains from your mug. It is a natural and safe cleaning agent that won’t harm your glassware.

Now that you have your tools and materials ready, it’s time to get started with cleaning your glass coffee mug. Follow these simple steps to get your mug looking clean and shiny once again:

1. Rinse Your Mug

The first step in cleaning your glass coffee mug is to rinse it under warm water. This will help to remove any loose dirt or debris that may be present on the surface. 

Make sure to use warm water, as hot water can cause the glass to crack or break.

2. Add Dish Soap

Next, add a small amount of dish soap to your mug. Use a mild soap that is free from harsh chemicals and fragrances, as these can leave behind residue or streaks on your glass. 

You can either apply the soap directly to the mug or add it to your sponge or brush.

3. Scrub Your Mug

Using your sponge or brush, gently scrub the inside and outside of your mug. Pay special attention to any areas that may be stained or discolored, such as the bottom or the rim. 

Use a circular motion to remove any dirt or stains, taking care not to scratch the glass.

4. Rinse Thoroughly

After you have finished scrubbing your mug, rinse it thoroughly under warm water. Make sure to remove all traces of soap, as any residue can affect the taste of your coffee. You can also use a clean cloth or paper towel to wipe the mug dry.

5. Use Baking Soda (Optional)

If your mug has stubborn stains or odors that won’t come out with dish soap alone, you can use baking soda to give it an extra boost. 

Mix a small amount of baking soda with warm water to create a paste, and then use your sponge or brush to apply it to the stained areas. Scrub gently, and then rinse thoroughly with warm water. 

I found that baking soda works just as well as Bar Keepers Friend.

This Bar Keepers Friend kit contains a microfiber towel and scrubbing sponge paired with the cleanser and polish degreaser. It’s perfect for gentle cleaning and polishing on all kinds of surfaces, including ceramic, glass, and steel.


6. Use Vinegar (Optional)

If your mug has mineral deposits or hard water stains that won’t come out with dish soap or baking soda, you can use vinegar to remove them. 

Fill your mug with a 50/50 mixture of white vinegar and water, and let it sit for a few hours or overnight. 

The acid in the vinegar will help to dissolve the mineral buildup, making it easier to clean. After soaking, rinse your mug thoroughly under warm water and dry with a clean cloth.

Tips for Keeping Your Glass Coffee Mug Clean and Shiny

Now that you know how to clean your glass coffee mug, it’s important to take steps to keep it looking its best over time. Here are a few tips to help you maintain your mug’s appearance and quality:

  • Rinse your mug after each use: Rinse your mug thoroughly under warm water after each use to remove any coffee residue or oils. This will prevent stains and odors from building up over time.
  • Avoid abrasive cleaners: Avoid using abrasive cleaners, such as steel wool or harsh chemicals, as these can scratch or damage your glass mug. Stick to gentle cleaners like dish soap, baking soda, and vinegar.
  • Store your mug properly: Store your mug in a dry, dust-free area to prevent dust and debris from settling on the surface. Avoid stacking your mugs, as this can cause scratches or chips.
  • Use a coaster: Use a coaster under your mug to protect the surface of your coffee table or countertop from scratches or stains. This will also help to prevent condensation from forming on the bottom of the mug.
  • Replace your mug if it becomes chipped or cracked: If your mug becomes chipped or cracked, it is best to replace it. A damaged mug can be dangerous to use, as it may break or shatter during use.
