How to Get Wax Out of Silicone Molds Without Breaking?

Silicone molds are widely used in many different industries, from casting resin and metal to making candles and soaps. However, when used to make wax products, the molds can become coated with a layer of wax that can be difficult to remove.

This buildup can affect the quality of the final product and create a sticky film on the surface of the mold, making it hard to use it again. Removing wax from silicone molds can be a challenging task, but with the right methods and tools, it can be easily done.

In this article, we will discuss four different methods to remove wax from silicone molds: the vinegar method, the baking soda method, the oven method, and the freezer method.

We will also compare the cost, effectiveness, and ease of use of each method, and provide tips and precautions to ensure the safe and successful removal of wax from silicone molds.

4 Methods to Get Wax Out of Silicone Molds Without Breaking?

1. Vinegar

The vinegar method is an effective and easy way to remove wax from silicone molds. It uses the natural cleaning properties of vinegar to break down and dissolve the wax, making it easy to wipe away. Here is a step-by-step guide on how to use the vinegar method, along with the tools you will need:

Tools needed:

• White vinegar
• Boiling water
• Bowl or container big enough to hold the mold
• Scrub brush or sponge
• Clearwater

Step-by-step guide:

• In a bowl or container, mix equal parts white vinegar and boiling water.
• Place the silicone mold in the vinegar and water mixture and make sure it is fully submerged.
• Let the mold soak in the vinegar and water mixture for at least 1 hour.
• After soaking, use a scrub brush or sponge to gently scrub the surface of the mold to remove any remaining wax.
• Rinse the mold thoroughly with clear water.
• Repeat steps 2-5 if necessary until all the wax is removed.
• Once the mold is clean, dry it thoroughly before using it again.

Note: It is important to use white vinegar only and avoid using any other type of vinegar as it may damage the mold. Also, make sure to use the mold only for the intended purpose after cleaning as it may affect the outcome of your product.

2. Baking Soda

The baking soda method is another effective way to remove wax from silicone molds. Baking soda is a natural abrasive that can break down and remove the wax without damaging the mold. Here is a step-by-step guide on how to use the baking soda method, along with the tools you will need:

Tools needed:

• Baking soda
• Hot water
• Bowl or container
• Scrub brush or sponge
• Clearwater
• Soap

Step-by-step guide:

• In a bowl or container, mix baking soda with hot water to form a paste.
• Apply the baking soda paste to the surface of the silicone mold, making sure to cover all areas where there is wax buildup.
• Use a scrub brush or sponge to gently scrub the surface of the mold, focusing on areas where there is wax buildup.
• Rinse the mold thoroughly with clear water to remove any remaining baking soda paste.
• Wash the mold with soap and clear water to remove any remaining residue.
• Repeat steps 2-5 if necessary until all the wax is removed.
• Once the mold is clean, dry it thoroughly before using it again.

Note: Be careful not to use too much baking soda as it may cause damage to the mold. If the baking soda paste is too thick, you can add more hot water to make it a less abrasive consistency. Also, make sure to use the mold only for the intended purpose after cleaning as it may affect the outcome of your product.

3. Oven

The oven method is a quick and effective way to remove wax from silicone molds. The heat from the oven will soften the wax, making it easy to wipe away. However, this method must be done with caution as it may damage the mold if the temperature is too high or it’s left in the oven for too long. Here is a step-by-step guide on how to use the oven method, along with the tools you will need:

Tools needed:

• Oven
• Denatured Alcohol
• Sponge or cloth

Step-by-step guide:

• Preheat your oven to a low temperature, around 150-200 degrees Fahrenheit.
• Place the silicone mold in the oven and let it warm for about 5-10 minutes.
• Carefully remove the mold from the oven using oven mitts.
• Wipe the surface of the mold with a sponge or cloth dipped in denatured alcohol. The heat from the oven will have softened the wax, making it easy to wipe away.
• Repeat steps 2-4 if necessary until all the wax is removed.
• Once the mold is clean, dry it thoroughly before using it again.

Note: It is important to keep an eye on the mold while it’s in the oven, as the mold may become too hot and lose its shape. Also, make sure to use the mold only for the intended purpose after cleaning as it may affect the outcome of your product.

4. Freezer

The freezer method is another effective way to remove wax from silicone molds. The low temperature of the freezer will cause the wax to freeze and become brittle, making it easy to remove with a plastic scraper or butter knife. Here is a step-by-step guide on how to use the freezer method, along with the tools you will need:

Tools needed:

• Freezer
• Plastic scraper or butter knife
• Clearwater
• Soap (optional)

Step-by-step guide:

• Place the silicone mold in the freezer and let it sit for at least 2-3 hours.
• Carefully remove the mold from the freezer using oven mitts.
• Use a plastic scraper or butter knife to gently scrape away the frozen wax. The low temperature of the freezer will have caused the wax to freeze and become brittle, making it easy to remove.
• Rinse the mold thoroughly with clear water to remove any remaining wax or debris.
• (optional) Wash the mold with soap and clear water to remove any remaining residue.
• Repeat steps 2-5 if necessary until all the wax is removed.
• Once the mold is clean, dry it thoroughly before using it again.

Note: Be careful not to apply too much pressure when scraping the wax as it may damage the mold. Also, make sure to use the mold only for the intended purpose after cleaning as it may affect the outcome of your product.
