Brilio.net – Stainless steel glasses are a mainstay because of their extraordinary durability. Apart from being durable for years of use, this glass is also very flexible as a container for hot coffee or fresh iced drinks.

However, this material has one weakness: it can easily dent if hit by a hard object. Many people think that if it is dented, its shape will not return to its original shape. Apparently, there is a simple trick shared by a YouTuber named Brice Kelly to solve this problem.

Interestingly, you don’t need complicated carpentry tools. Just use one item that you definitely have in your kitchen.

Steps to Repair Stainless Glass

Here is a practical guide that you can follow at home BrilioFood from YouTube Brice Kelly, Wednesday (4/2/2026).

“To restore dented stainless steel glasses, you only need the help of one kitchen tool,” he said in the video narration.

1. Prepare the main tools

The only tool you need is a tablespoon. Make sure the spoon you use is also made of sturdy stainless steel so that it can provide the right pressure.

2. Identify the Damaged Area

Look for dents, either on the bottom or sides of the glass. Make sure the glass is stable when you start fixing it.

3. Do a light tap

Tap the back of the spoon against the area around the dent. This technique relies on pressure from metal taps to push the dented surface back into its original position.

4. Repeat until even

In his uploaded video, Brice Kelly only needed about 8 taps until the glass surface was smooth again.

Why Does This Work?

The tapping of the metal spoon against the surface of the glass creates vibrations and mechanical stress that forces the flexible stainless material to return to its original shape. As a result, your favorite glass can look normal again without leaving any noticeable marks.

FAQ How to Repair a Dented Stainless Steel Cup

1. Can this method be used for all types of dents?

This trick is very effective for light or moderate dents. If the dent is too deep or the metal has been bent sharply, the result may not be 100% smooth, but it can still reduce the damage.

2. Will the tapping of the spoon not damage the coating of the glass?

As long as you tap with measured force and use a stainless spoon, the risk is very small. Avoid hitting too hard so as not to create new depressions.

3. Can I use a small hammer instead of a spoon?

Yes, but you have to cover it with a cloth so that it doesn’t damage the surface texture of the glass or leave permanent scratches.

4. Is this method safe for vacuum flasks (thermos)?

For glasses that have two layers (vacuum insulation), this method must be done more carefully so as not to damage the airtight seal inside.

5. What if the dent is in a hard-to-reach interior?

You can use a longer spoon handle or other blunt instrument to push in the opposite direction, but the external tapping technique is usually easier to level the surface.
