Fog machines are a must-have for Halloween parties, theater productions, and special effects, but store-bought fog juice often contains glycerin, which you may not have on hand. The good news? You can make homemade fog juice without glycerin using a few simple household ingredients.
In this guide, you’ll learn:
✔ How to make fog juice without glycerin
✔ Alternative ingredients for thick, long-lasting fog
✔ How to use homemade fog juice in a fog machine
✔ Troubleshooting common fog machine issues
Why Avoid Glycerin in Fog Juice?
Glycerin is commonly used in fog juice because it helps create a dense, slow-dissipating fog. However, some people prefer glycerin-free alternatives because:
✔ It’s hard to find – Not everyone keeps glycerin at home.
✔ It can clog fog machines – If mixed improperly, glycerin can leave residue in the machine.
✔ It creates an oily mist – Some users find that glycerin-based fog feels sticky or heavy.

Best Homemade Fog Juice Recipes Without Glycerin
1. Dry Ice Fog Juice (Best for Thick, Low-Lying Fog)
If you want dramatic, thick fog that hugs the ground, dry ice is a great option. It doesn’t require a fog machine and works instantly.
🔹 Ingredients:
- 1 gallon hot distilled water
- 5–10 lbs dry ice (available at most grocery stores)
- A large heat-resistant bowl or bucket
🔹 Instructions:
1️⃣ Fill a large heat-resistant bowl or bucket with hot distilled water.
2️⃣ Carefully drop small chunks of dry ice into the water.
3️⃣ Watch as thick, eerie fog begins to spill over the sides.
4️⃣ Add more dry ice as needed to maintain the effect.
🔹 Best For: Halloween, haunted houses, theater productions, and spooky parties.
🔹 Pros:
✔ Creates thick, low-lying fog instantly
✔ No fog machine required
✔ Completely non-toxic
🔹 Cons:
❌ Short-lasting—fog dissipates as the dry ice melts
❌ Requires gloves & ventilation—handling dry ice can cause burns
⚠ Safety Warning: Never touch dry ice with bare hands—use gloves or tongs. Also, ensure proper ventilation to avoid CO₂ buildup in enclosed spaces.
2. Baking Soda & Vinegar Fog Juice (Best for Small Fog Effects)
If you want a simple misting effect without a fog machine, a baking soda and vinegar reaction can work.
🔹 Ingredients:
- 2 cups distilled water
- 2 tablespoons baking soda
- 1 tablespoon vinegar
🔹 Instructions:
1️⃣ In a heat-safe bowl, mix baking soda and distilled water.
2️⃣ Slowly pour in vinegar—it will start bubbling and producing a light fog-like mist.
3️⃣ Place a small fan near the mixture to help spread the fog.
🔹 Best For: Science experiments, DIY fog effects, and home party tricks.
🔹 Pros:
✔ Super easy to make
✔ Safe for indoor use
✔ No special equipment needed
🔹 Cons:
❌ Fog is very light and short-lived
❌ Not suitable for fog machines
3. Mineral Oil & Distilled Water Fog Juice (Best for Fog Machines)
If you need a fog machine-friendly alternative to glycerin-based fog juice, mineral oil is an excellent substitute. It creates a light, smooth fog effect without clogging the machine.
🔹 Ingredients:
- 2 cups distilled water
- 1 teaspoon food-grade mineral oil (or baby oil)
🔹 Instructions:
1️⃣ Mix distilled water and mineral oil in a container.
2️⃣ Pour the mixture into your fog machine’s reservoir.
3️⃣ Turn on the fog machine and let it warm up.
4️⃣ Adjust the machine settings to control fog density and output.
🔹 Best For: Fog machines used in parties, theaters, and photography.
🔹 Pros:
✔ Works with most fog machines
✔ Non-toxic and safe for indoor use
✔ Longer-lasting fog compared to water-only mixtures
🔹 Cons:
❌ Too much mineral oil can clog the machine
❌ Lighter fog compared to glycerin-based mixtures
⚠ Pro Tip: Use only food-grade mineral oil to avoid harmful fumes.
How to Use Homemade Fog Juice in a Fog Machine
✅ Step 1: Make sure your fog machine is clean before adding homemade fog juice.
✅ Step 2: Pour the mixture into the fog machine’s reservoir.
✅ Step 3: Turn on the machine and let it warm up completely.
✅ Step 4: Adjust the settings for thicker or lighter fog.
✅ Step 5: Use a fan to spread the fog throughout the space.
🔹 Pro Tip: Always test a small batch first to ensure your homemade fog juice works well with your machine.
Common Problems & Troubleshooting
🚧 Fog is too thin or disappears quickly?
✔ Add a bit more mineral oil for a denser effect.
✔ Try dry ice fog for a thicker, ground-hugging mist.

✔ Ensure the machine is fully heated up before use.
✔ Use only distilled water to prevent clogging.
🚧 Fog juice causing residue or clogging?
✔ Clean the machine after every use with a vinegar-water rinse.
