To get the effect you want and protect your gear, use only fog machine fluid that matches your machine and event needs.

• Water‑based fog fluid: The most common option for home, party, and stage foggers. It’s designed to vaporize cleanly in standard heaters.
• Effect type matters: Choose standard/medium density for general use, high‑density/long hang time for thicker clouds, or quick‑dissipating for short bursts and geyser-style effects.
• Check your manual: Some units specify the fluid type and viscosity. Avoid oil‑based fluids unless your machine explicitly supports them.
• Don’t improvise: Household liquids, perfumes, and plain water can cause damage.

You’ll find a range of fog, haze, and cleaning fluids on Walmart.com, so you can match fluid type to your machine and venue.

Fog machines rely on fluids formulated to create visible particles. Distilled water alone typically won’t produce a proper fog effect and can stress components.

• Performance: Water lacks the ingredients that form lasting fog, so you may see little to no effect.
• Wear and tear: Running plain water can put extra strain on the pump and heater block, potentially leading to clogs or overheating over time.
• Best practice: Stick with compatible fog fluid recommended by your machine’s manual.
• Maintenance: For upkeep, use a manufacturer‑approved fog machine cleaning solution and follow your manual for flushing or cleaning cycles.

Using the right fluid can help maintain consistent output while reducing buildup inside the machine.

If you’re out of fog juice, there isn’t a safe household substitute that’s recommended for fog machines.

• Avoid DIY stand‑ins: Mixing your own liquids or using other substances can create residue, clog heaters, or void warranties.
• Use the right category: If you want lighter atmosphere, consider haze/fazer fluid—but only in a machine designed for haze. For thick effects, look for high‑density fog fluids made for standard foggers.
• Don’t cross over: Snow or bubble fluids are for specialized machines and aren’t interchangeable with foggers.

Your best bet is to pick up a compatible fog fluid that matches your effect (standard, long‑hang, or quick‑dissipating). Walmart.com stocks multiple types for different machines and venues.

It’s understandable to be curious, but most manufacturers advise against homemade fog fluid. DIY mixes can be unpredictable and may lead to issues.

• Machine health: Improper mixtures can increase residue, clog heaters, and shorten component life.
• Output quality: Particle size and hang time vary widely with DIY blends, so effects may be inconsistent.
• Warranty and safety: Using unapproved fluids may affect warranty coverage and isn’t recommended for public venues.
• Better approach: Choose a compatible, water‑based fog fluid formulated for your machine and desired effect, and follow your manual.

If sensitivities are a concern, review product labels and usage guidelines, and run your machine in a well‑ventilated space with reasonable output levels.

Each fluid is designed for a specific machine and visual effect.

• Fog fluid: Creates visible clouds or plumes. Available in standard, high‑density (longer hang), and quick‑dissipating formulas for burst effects.
• Haze/fazer fluid: Produces a fine, even mist that enhances beams and lighting without thick clouds. It’s thinner and made for haze/fazer machines.
• Snow fluid: Used in snow machines to simulate falling flakes or foam; it won’t work in a fogger.

Compatibility matters: Don’t interchange these fluids—use the type your machine specifies. Walmart.com offers fog, haze, and snow fluids so you can match the fluid to your device and the look you’re going for.
