Gold is a precious metal that has been a valuable commodity for centuries. People have been using gold as an investment and a form of currency for millennia. Gold is also a popular item to collect, and it can be used to make beautiful jewelry. While it’s easy to spot a gold item by its color, it can be hard to tell the difference between real gold and fake gold. To make sure a gold item is genuine, it’s important to test it.

Fortunately, there are ways to test gold at home without having to take it to a professional or a lab. One of the most popular methods is to use bleach. This method is known for being simple, effective, and relatively inexpensive. Here’s a step-by-step guide to testing gold with bleach at home.

Step 1: Make Sure It’s Real Gold

Before you start testing gold with bleach, it’s important to make sure that the item you’re testing is actually gold. There are several ways to do this. You can use a magnifying glass to check for markings on the item that indicate it is real gold. These can include a hallmark, a karat rating, or a serial number. You can also use a gold testing kit, which will tell you if the item is real gold or not.

Step 2: Gather Your Supplies

Once you’ve determined that the item you’re testing is real gold, you’ll need to gather your supplies. The supplies you’ll need are:

  • Bleach
  • A small container
  • Q-tips or cotton swabs
  • A pair of tongs or tweezers
  • Gloves
  • Safety glasses

It’s important to use caution when dealing with bleach. Make sure you wear gloves, safety glasses, and other protective gear when handling the bleach.

Step 3: Prepare the Bleach Solution

Once you have all your supplies, you’ll need to prepare the bleach solution. Start by pouring the bleach into the container. Fill the container with enough bleach so that the gold item you’re testing will be completely submerged. Make sure the container is large enough so that you can safely handle it.

Step 4: Test the Gold Item

Once you’ve prepared the bleach solution, it’s time to test the gold item. Start by using the tongs or tweezers to carefully lower the gold item into the bleach. Make sure it is completely submerged. Allow the gold item to sit in the bleach for up to 15 minutes. As you wait, you’ll notice that the color of the bleach will change. This is a sign that the gold item is being affected by the bleach.

Step 5: Remove the Gold Item

After the gold item has been in the bleach for 15 minutes, you can remove it using the tongs or tweezers. Make sure to wear gloves while handling the item, as it will be covered in bleach. Place the gold item on a paper towel to dry.

Step 6: Check the Color

Once the gold item is dry, take a look at the color. If the gold item has turned green, it is likely fake. Genuine gold will not change color when exposed to bleach. If the item has not changed color, it is likely real gold. You can also use a Q-tip or cotton swab to dab a small amount of bleach on the gold item. If it does not change color, it is likely real gold.


Testing gold at home with bleach is a simple and effective way to determine if a gold item is real or fake. However, it is important to use caution when handling the bleach, as it can be dangerous. If you are ever in doubt, it is always best to take the gold item to a professional or a lab for further testing.
