Modified: May 19, 2022 · Published: May 19, 2022 by Irina Totterman · This post may contain affiliate links · Leave a Comment

Hello and welcome! Grab a cup of coffee and enjoy the recipe (or your next baking tip). Don’t forget to save it for later!

Quick summary: To clean silicone molds, wash them in hot water with a grease-cutting dish soap and a soft sponge, then rinse and let them air dry. For stuck-on residue, soak in hot soapy water first. To remove burnt marks and stains, soak with white vinegar and hot water or a baking soda paste, or warm the mold in a low oven before washing. Avoid abrasive scrubbers, solvents, and drying it inside out.

Silicone molds are like any other kitchen appliance, and you need to care for them to get the most out of them.

For starters, before using a new one, wash it thoroughly with soapy water, run hot tap water over the surface of the mold, then dry it.

Regular maintenance keeps your mold durable for years of use. Clean your molds immediately after use; don't let dirty molds sit until the next day.

The goal when cleaning silicone molds is to remove any stains, burn marks, and greasy substances. You can clean silicone bakeware by hand or in a dishwasher.

How to clean silicone molds

To clean your silicone mold by hand, use dishwashing soap that contains a grease-cutting agent. If desired, use a microfiber cloth.

But don't scrape it with a scrubby sponge! You risk damaging the material and forming micro-scratches, which might affect the pan's nonstick properties.

Another way to handwash is to soak your mold in the kitchen sink filled with hot, soapy water for one hour; the longer, the better.

Then wash it by hand in warm, soapy water (wear rubber dishwashing gloves if desired) or use a non-abrasive sponge. If the water is cold, add more hot water.

Rinse your mold with clean running water, preferably hot, and let it dry (it may take several hours). But don't use a kitchen towel to dry it, to avoid leaving fabric particles behind.

Finally, if desired, you can sterilize silicone. Just bring your silicone mold to the oven at 212°F (100°C) for 2 minutes.

If the silicone piece still feels sticky, use a dishwasher or the more aggressive cleaning steps below.

Are silicone molds dishwasher safe?

Generally speaking, almost all silicone molds are dishwasher safe, but it depends upon the quality of the silicone.

The poorer it is, the less the silicone mold will withstand the dishwasher's heat. So, once you purchase a new mold, always refer to the manufacturer's instructions.

Please read the silicone product description carefully and pay attention to the package information.

If the mold is dishwasher safe, avoid the intensive washing program. Instead, wash it with a cycle below 158°F (70°C) using a non-abrasive detergent.

Still, if you want to keep your molds in good condition for a long time, hand-washing is best.

How to remove burns, stains, and fat

From time to time, your silicone molds will need a more aggressive way to remove tough stains, marks, or residue. Here are a few different ways to handle whatever cleaning needs you have.

How to clean burnt silicone bakeware

One of the most common questions is how to clean burnt silicone bakeware. The best approach is to loosen the burnt residue first with white vinegar and hot water or a baking soda paste, or by warming the mold in a low oven, then wash it with grease-cutting soap.

If you need to remove burn marks, pour white vinegar into your silicone mold and add very hot water. Let it soak for 1 hour, then rinse with clean water.

To remove stubborn stains from silicone bakeware, the vinegar method also works.

Alternatively, you can use baking soda and hot water. Pour baking soda and hot water into a silicone mold, and let it sit for at least 1 hour.

Then rinse it thoroughly to remove the sodium bicarbonate. If left on, it may damage the silicone when you wash it with soap in the next step.

To finish, wash the mold with soap, rinse, and dry.

The best way to remove heavy stains on light-colored silicone pieces from darker foods is with hydrogen peroxide or chlorine bleach. These products will safely and effectively remove any discoloration fast.

Soak your mold in hydrogen peroxide or a mixture of 2 tablespoons of bleach per 2 cups of water for 24 hours. Then rinse very well and dry.

The easiest way to remove fat and other greasy substances is to run your molds through the dishwasher.

But how do you remove the crispy bits stuck to the silicone pan?

The solution for getting rid of those pesky bits from your bake is just as easy.

Put the pan in an oven at 350°F (175°C) for 10 to 15 minutes, then soak it in very hot, soapy water before rinsing.

How to clean silicone bakeware

Silicone baking molds are durable, nonstick, and easy to clean, which is part of what makes baking with silicone molds so convenient. So it makes perfect sense why you want one for your next cupcake or muffin recipe.

One of the most important things to remember about preserving your bakeware is that it needs regular cleaning.

But is there any difference in cleaning silicone baking mats, silicone cookware, and silicone chocolate molds?

Not really. Clean silicone mats, silicone baking sheets, baking cups, and muffin cups using the common methods listed in this post. Just remember that your silicone bakeware must be impeccable before storing.

Avoid these common mistakes.

Keeping your silicone molds like new is not complicated, but there are a few things to avoid.

  • Avoid using abrasive sponges, scouring pads, and other rough tools, such as a toothbrush, a stiff-bristled brush, or harsh detergents, to clean your resin silicone molds. They can damage the molds and leave permanent micro-scratches. Instead, wash your molds by hand with a soft sponge and non-abrasive detergent or mild soap.
  • Never use solvents to clean molds. This can damage them and degrade your products more quickly than you would expect.
  • Don't use boiling water to wash your molds. Instead, use warm water or hot water to remove burn marks and stains.
  • Also, never wipe silicone molds with a kitchen towel, as this can leave fabric particles behind and increase the chance of sticking before use. Instead, let your molds air dry thoroughly before storing them.
  • Here is a quick tip for drying the molds after washing. Don't reverse them inside out! Instead, let them dry, keeping their original shape. Preserving the mold's integrity is essential.
  • Never place your silicone mold directly on the flame of your gas stove or any hot surface to dry out. Also, avoid UV light, which can dry out and damage the silicone. Instead, let it air-dry at room temperature, away from direct sunlight.
  • Don't use cooking sprays, or at least limit their use. Whether you like it or not, cooking sprays lead to a greasy buildup in the silicone molds. Instead, don't grease your molds. You don't really need this extra step since they are naturally nonstick.

FAQ

Why does your silicone mold stick?
A "cheap" silicone mold may stick if you wipe it after washing, which is why it is best to air dry it. To keep your bake from sticking, place the empty mold in cold water, then pour in your batter. After baking, let the cake rest for at least 10 to 15 minutes before unmolding.

Why has my silicone mold turned white?
Grease builds up and white residue forms on a silicone mold when it is not cleaned properly. The good news is that white spots are not a sign of wear. Fill the mold with water and place it in the freezer to lift them, then pop out the ice cube with the trapped fat, and the mold will look like new.

How do you get mold out of silicone?
Mold and mildew are usually caused by a lack of proper drying after cleaning, so always let the mold air dry completely before storing it. To remove mildew, wash the mold with soapy water and soak it in a mix of hot water and white vinegar for about an hour, then rinse well and air dry. If it persists, throw the mold away.

How do you remove baked-on grease from silicone bakeware?
Soak the bakeware in hot water with a grease-cutting dish soap for up to an hour to soften the grease, then scrub gently with a soft sponge or brush. For stubborn buildup, warm the mold in a 350°F (175°C) oven for 10 to 15 minutes, then wash it in very hot soapy water.

Can you use Dawn dish soap to clean silicone?
Yes, a grease-cutting dish soap such as Dawn is one of the best cleaners for silicone. Combine it with hot water and a soft sponge, and avoid abrasive scrubbers that can scratch the surface.

What kills bacteria on silicone?
Hot, soapy water removes most bacteria, and you can sanitize a mold further by boiling it for a few minutes or soaking it in a diluted white vinegar solution, as long as the manufacturer allows it.

Why does a silicone mold give food a plastic taste?
Poor-quality silicone and baking above the temperature the maker recommends can give food a plastic taste. If this happens, the mold has likely released chemicals into the dish, so discard the mold. To avoid it, buy high-quality silicone products and follow the recommended temperatures.

Can you boil silicone?
It depends on the silicone's quality. Check the manufacturer's instructions to see whether you can boil your silicone mold.

How long do silicone molds last?
With proper care, silicone molds can last for many years. To get the most out of them, clean and store them correctly after every use.
