Why Does My Artificial Tree Smell Like Plastic And How To Eliminate The Odor

Every holiday season, millions of homes welcome an artificial Christmas tree as a convenient, reusable centerpiece of festive cheer. But for many, that first whiff upon unpacking can be less “winter wonderland” and more “factory floor.” The unmistakable plastic smell clinging to synthetic trees is common—but not inevitable. Understanding where the odor comes from and how to neutralize it effectively ensures your home fills with the warmth of the holidays, not the fumes of polyvinyl chloride.

This guide dives into the science behind the scent, explores safe and practical removal strategies, and provides long-term storage solutions to prevent recurrence. Whether you're setting up a newly purchased tree or reviving one from last year’s attic stay, you’ll find actionable steps to restore freshness without compromising safety or decor quality.

The Science Behind the Plastic Smell

Artificial trees are typically made from polyvinyl chloride (PVC), a durable and flame-resistant plastic widely used in consumer products. During manufacturing, PVC is combined with softening agents called phthalates and stabilizers to improve flexibility and longevity. These chemical compounds can off-gas—release volatile organic compounds (VOCs)—especially when stored in warm, enclosed spaces or exposed to temperature changes.

The odor most people describe as “plastic-like” is actually a mixture of these VOCs, including ethyl acetate, butyl acetate, and traces of chlorine-based byproducts. While generally not toxic at low levels, prolonged exposure in poorly ventilated areas may cause headaches, eye irritation, or respiratory discomfort in sensitive individuals, particularly children and pets.

“Off-gassing from PVC products is real and measurable. Though short-term exposure isn’t typically dangerous, reducing indoor concentrations improves air quality significantly.” — Dr. Lena Torres, Environmental Health Scientist, Indoor Air Quality Institute

The intensity of the smell often depends on the tree’s age, storage conditions, and manufacturing origin. Newer trees tend to emit stronger odors due to higher residual VOC content, while older trees may still release scent after years in storage if not properly aired out.

Step-by-Step Guide to Eliminate the Odor

Removing plastic smell isn’t about masking it with overpowering fragrances—it’s about neutralizing the source and accelerating the off-gassing process safely. Follow this timeline-based approach for optimal results:

1. Unpack Early (7–10 Days Before Display): Set up your tree in a well-ventilated area such as a garage, sunroom, or covered porch. Avoid placing it near heat sources like radiators or space heaters, which can increase VOC emissions temporarily.
2. Dry Out and Air Out: Let the tree stand fully assembled for 48–72 hours with fans circulating air around it. Position oscillating fans at base and mid-level to reach hidden crevices between branches.
3. Vacuum Gently: Use the brush attachment on your vacuum cleaner to remove dust and surface residues from branch tips and trunks. Dust can trap odors and reduce cleaning effectiveness later.
4. Baking Soda Spray Treatment: Mix 1 cup of water, 1 tablespoon of baking soda, and 5 drops of essential oil (optional) in a spray bottle. Lightly mist the inner branches—avoid soaking. Baking soda neutralizes acidic VOCs, while essential oils add subtle natural fragrance.
5. Activated Charcoal Exposure: Place open containers of activated charcoal around the base of the tree during airing. Charcoal absorbs lingering gases far more effectively than baking soda alone.
6. Final Indoor Placement: Once the smell is faint or gone, move the tree indoors. Continue using a portable air purifier with a carbon filter near the tree for the first few days inside.

Tip: Never use bleach, ammonia, or strong solvents on artificial trees—they can degrade PVC, discolor foliage, and create hazardous fumes.

Effective Odor Removal Methods Compared

Not all deodorizing techniques are equally effective or safe. The table below compares popular methods based on speed, safety, cost, and long-term impact.

Method	Effectiveness	Safety	Cost	Best For
Natural Airing (Outdoors/Garage)	High	Very Safe	Free	All trees, especially new ones
Baking Soda + Water Spray	Moderate-High	Safe	Low	Targeted odor neutralization
Activated Charcoal Bags	High	Very Safe	Medium	Enclosed storage or slow off-gassing
Essential Oil Misting	Low-Moderate	Safe (if diluted)	Medium	Masking mild odors only
Ozone Generator	Very High	Risky (not pet/child-safe)	High	Severe cases (use with caution)

Note: Ozone generators can break down VOC molecules rapidly but produce ozone—a lung irritant. They should only be used in unoccupied spaces and followed by thorough ventilation before re-entry.

Storage Mistakes That Bring Back the Smell

Even after successfully removing the odor, improper storage can cause it to return each year. Heat, humidity, and poor airflow trap residual chemicals and encourage continued off-gassing. Many people store their trees in sealed plastic bags or damp basements, creating ideal conditions for odor buildup.

• Storing in attics or garages without climate control exposes trees to temperature swings that accelerate chemical breakdown.
• Compressing the tree too tightly prevents air circulation and traps stale gases within folds.
• Using non-breathable containers like heavy-duty trash bags suffocates the material and promotes musty overtones alongside plastic notes.

Tip: Store your tree disassembled in breathable fabric bags or cardboard boxes in a cool, dry closet—not in sealed plastic bins.

Mini Case Study: The Johnson Family Tree Revival

The Johnsons in Minneapolis bought a pre-lit artificial tree in 2021. Each November, they dreaded unpacking it—the sharp plastic smell filled their living room for nearly a week. In 2023, after their youngest child developed sensitivity-related headaches, they decided to act.

They set up the tree in their attached garage two weeks before decorating. Using two box fans and three open bowls of activated charcoal placed around the base, they circulated air continuously. Every other day, they lightly sprayed inner branches with a baking soda solution. After five days, the odor was barely noticeable. When moved indoors, they ran a HEPA + carbon-filter air purifier nearby for three days.

Result: No plastic smell during display, and no recurrence of symptoms. They now follow this routine annually, cutting initial airing time to just 72 hours.

Checklist: How to Keep Your Artificial Tree Fresh Year-Round

Use this checklist each season to ensure your tree stays clean, odor-free, and ready for display:

• ☑ Unpack and inspect the tree early—don’t wait until December 20th.
• ☑ Set up in a ventilated, temperate space (garage, shed, sunroom).
• ☑ Run fans to circulate air around all sections of the tree.
• ☑ Vacuum branches gently to remove dust and residue.
• ☑ Apply a light baking soda mist to inner foliage (avoid lights and electrical parts).
• ☑ Place activated charcoal bags near the trunk and under lower branches.
• ☑ Allow 3–7 days of airing before moving indoors.
• ☑ Use a carbon-filter air purifier near the tree for the first few days inside.
• ☑ Clean and dry the tree before storing.
• ☑ Store in a breathable container in a climate-stable location.

Frequently Asked Questions

Is the plastic smell from artificial trees harmful?

Short-term exposure to the off-gassed VOCs from most artificial trees is unlikely to cause serious health effects in healthy adults. However, individuals with asthma, chemical sensitivities, or young children may experience irritation. Reducing exposure through ventilation and odor removal minimizes any risk.

Can I wash my artificial tree to remove the smell?

No—submerging or heavily wetting an artificial tree can damage wiring in pre-lit models and promote mold growth in stored materials. Instead, use dry methods like vacuuming and targeted sprays with minimal moisture. Always disconnect lights before any treatment.

Will the plastic smell go away on its own?

Yes, given enough time and airflow, most artificial trees will off-gas completely within a few weeks. However, proactive measures like airing, baking soda, and charcoal dramatically shorten this period—from weeks to days.

Long-Term Prevention: Building a Scent-Free Tradition

Eliminating the plastic smell once is helpful; preventing it every year is transformative. Consider upgrading to newer trees labeled “low-odor” or “phthalate-free,” increasingly available from eco-conscious brands. Some manufacturers now use polyethylene (PE) foliage, which has a more natural texture and emits fewer VOCs than traditional PVC.

If replacing isn’t feasible, commit to a yearly refresh ritual: unpack, air, treat, and purify. Treat your artificial tree like any high-use household item that needs seasonal maintenance—like a patio umbrella or winter coat. Over time, off-gassing diminishes naturally, and with proper care, even older trees can become virtually odorless.

“The key is consistency. One deep airing won’t fix years of trapped gases. But a disciplined annual routine transforms problem trees into cherished centerpieces.” — Mark Renaldi, Home Appliance & Décor Technician
