Even with the finest polycarbonate molds, sometimes things don’t go as planned. Instead of perfectly molded chocolates, you might end up with stubborn sticking ones. For your assistance, we’re here to clean up these chocolate troubles with practical solutions.

Problem 1. Chocolate Sticks to the Mold

In case your chocolate refuses to come out of the mold, the likely culprits may turn out to be insufficient tempering. Apart from that, you can also face this annoying issue due to improper cooling or residual grease in the mold.

Ways to Fix the Chocolate Sticking Within the Mold Issue

• Check Your Tempering: When you choose to temper chocolates, they usually shrink slightly as they cool. Thanks to this phenomenon, the release becomes much easier. 
• Get Your Mold Cleaned: Remove any leftover cocoa butter or grease with a lint-free cloth before use.

Problem 2. Chocolate Appears Dull or Cloudy

Sometimes, improper cleaning can lead to scratched molds, which in turn cause chocolate to appear lackluster. Besides that, professionals also face this effect when they fail to temper the batter in the best way possible.

Ways to Improve the Dull-Looking Chocolates 

• Polish Your Mold Before Use: Your molds should be spotless for that flawless shine. For this, always buff these molds with some dry cloth before pouring chocolate. 
• Inspect Mold for Scratches: As scratches create uneven surfaces, make sure polycarbonate molds are free from them to avoid dull spots. 

Problem 3. Water Spots Appear on the Mold

When your molds show signs of water spots, it means they weren't dried properly after washing. If your tap water has minerals, it can leave white streaks on your molds.

Ways to Avoid Water Spots on Your Polycarbonate Molds

• Dry Molds Immediately: After washing, wipe them without wasting any time with any microfiber cloth to prevent water stains.
• Air Dry Upside Down: Thanks to this technique, you will be able to prevent water from pooling inside the cavities and creating spots.

Problem 4. White Residue Forms on the Mold

Such a chalky white film on your molds may appear due to fat or sugar bloom. When your molds are not cleaned properly, these residues can also ruin the outlook of future batches of homemade chocolate.

Ways to Clean White Residue from Mold

• Utilize White Vinegar: Start by dampening any soft cloth with food-safe white vinegar and gently wiping the mold. Afterward, simply rinse the polycarbonate molds with warm water to avoid any smell.
• Try Some Baking Soda Paste: To remove these annoying marks, apply baking soda paste on molds using soft sponges. Doing so will enable you to break down stubborn fat or sugar bloom without any damage to molds.

Part 4. Storage Tips to Maintain Polycarbonate Chocolate Molds

After cleaning your molds to perfection, storing them correctly becomes just as important as washing them. Follow these storage tips to be ready for your next chocolate masterpiece. 

Tip 1. Store Your Molds in a Cool, Dry Place

Honestly speaking, polycarbonate molds hate humidity. Any type of moisture can lead to sugar bloom, which leaves an unwanted chalky film on your chocolates. Other than that, heat can cause chocolate release issues.

To deal with these situations, keep your molds in a room between 50 to 68°F with low humidity. Also, avoid storing your molds near ovens or dishwashers, as they can gradually deform the molds. 

Tip 2. Avoid Direct Sunlight Exposure

Like other delicate materials, UV exposure can also cause the polycarbonate to become brittle over time. Therefore, store such molds within some dark cabinet or drawer to prevent damage.

Tip 3. Stack These Molds Carefully or Store Separately

When you stack multiple molds, they get prone to scratches, which ruin their smooth surface. Simply place parchment paper or silicone mats between stacked molds. If possible, keep each mold in its own compartment to fully prevent friction damage. 

Conclusion

All in all, cleaning polycarbonate chocolate molds might seem challenging. However, this process is worth every second to make the chocolate-making task even more rewarding. With a bit of patience, you will be able to craft chocolates that come out smooth.

Hi All,
How do you get a beautiful shine on your chocolates. Do you wash the moulds in water every time you have used them, or do you just polish the moulds? Do you pre coat them with cocoa butter? Looking forward to your reply.

Thanks for your reply, much appreciated I went to a demo by Kirsten Tibbals (Masterchef Australia) the other day, and she wipes down her moulds in 100% medical alcohol each time to get perfect shine Thanks a lot, that is very helpful. The topic of cocoa butter crystallization and mold usage/prep is a long and technical one, but I hope my rambling answer helps answer some of the key points to your questions. Best of luck! ….and to follow up on the response to spraying cocoa butter, it is true that most often it is colored and used for decoration. However, sometimes it can be useful to work with plain coco butter instead. Remember that it is the cocoa butter itself, and not the pigments the contain, that is really giving you the shininess (though some formulations, i.e. jewel/ metallic do help give it a boost). So imagine a situation where you were molding in white chocolate, but wanted to add some dark chocolate stripes prior and still wanted the shine that comes from spraying. Then in that case a very thin coat of plain cocoa butter applied first will allow both the dark stripes and the white shell to be very shiny and you only have to spray once. But it is very important that plain cocoa butter be sprayed very fine. If the spray is too thick, then the final product will have a more opaque look, almost cloudy. Remember, well crystalized cocoa butter is more “yellow” than it is clear. When polishing, its advisable to use a non abrasive soft cloth like cotton balls or microfiber. If the molds have been stored well, then you can buff the cavities while they are cold and achieve great results. However, if you do need to clean them, then I always like to polish immediately after cleaning while they are still warm. If needed a small amount alcohol can help eliminate any remaining residue. Vodka works well, but I something higher Proof (i.e. Everclear) works even better and with a faster evaporation time. If using alcohol, I still like to go back with a dry cloth for a quick buff up. When we work with molds in the correct way, a thin residual film of coca butter is left inside the cavity after de-molding. In theory, this film is what sets up the shine for the next room and allows us to continue using the same mold without having to immediately clean them. If one stores them (in between rounds) in conditions that are to hot, the quality of that crystalized butter will deteriorate thus necessitating, at the least some polishing and potentially even some cleaning. The short answer to your question, is that in general it should not be necessary to wash your molds after each use, but a thorough polish every time is definitely helpful way to maintain the shine prior to reusing. That said, there are some circumstances / conditions that necessitate cleaning after each use. The most obvious would be if any contaminants get into the mold, i.e. dust, dirt, fillings etc.. Also, if one is using colored cocoa butters and any happens to be stuck inside the cavity, then it might be necessary to clean again. At the same time, one needs to consider how they are storing the molds in between usages. Hi @cookieco,
Shine and polishing….no small thing when working with molds! @cookieco –

I am assuming you are talking about bonbons and not bars?

Molds are not usually washed between each use. However, if you are looking for a high shine then polishing between each use is very common. Cotton balls (or other lint-free soft material) and alcohol. Cheap vodka works well and is, well, cheap. You don’t want to use gin (flavored) or brown spirits.

Spraying in cocoa butter is normally, in my experience, associated with decorating with colors, not as a clear coat for added shine.
