Is wood stain toxic? It’s a valid concern, especially if you’re using it in a space where you and your family spend a lot of time.
After all, you don’t want to expose yourself or your family to toxic chemicals while working on a project.
That’s why it’s important to know whether or not wood stain is toxic and what you can do to minimize any potential risks.
In this article, we’ll explore the ingredients in wood stain, discuss any potential health concerns, and provide some tips for using wood stain safely.
So let’s dive in.
Is Wood Stain Toxic?
Wood stains are mostly toxic during the application and drying processes. Once fully cured, typically after 30 days, they are no longer harmful and irritating to the airways. Even though these stains are manufactured in compliance with the FDA regulation, it’s important to exercise precautions when using them.
What Makes Wood Stain Toxic?
But before we delve into its toxicity, have you ever wondered about the shelf life of wood stain? Understanding its longevity can provide insights into both its potential dangers and effective usage.
The toxicity of wood stains can vary depending on the specific ingredients used. In general, wood stains contain a combination of pigments, solvents, and resins.
The pigments provide color, while the solvents and resins help the stain adhere to the wood and provide protection.
Here are a few common ingredients that may contribute to the toxicity of wood stains:
- Petroleum distillates: are colorless, flammable liquids with a mild gasoline or kerosene-like odor.
- Varnish: This is a clear, hard finish typically made from a blend of synthetic resins like urethanes, solvents, and drying oils. Some solvents used in varnish include chemicals like xylene, formaldehyde, and toluene.
- Linseed oil: is a drying oil commonly used in wood stains as a binder. It also helps the color penetrate the wood and protect it from moisture.
- Hydrocarbons: are substances that contain only carbon and hydrogen and are often found in wood stains.
- Alcohol and Alkanes: These are hydrocarbons that are found in some wood stains as solvents or drying agents.
- Additionally, wood stains may contain volatile organic compounds (VOCs), which are chemicals that evaporate into the air at low temperatures. High levels of VOCs can create air pollution and negatively affect human health.
Water-based Wood Stain Toxicity
Water-based wood stains are a great alternative to traditional oil-based stains, as they are generally less toxic and emit fewer volatile organic compounds (VOCs).
They also dry faster and are easy to clean using soap and water. However, it’s important to avoid water-based stains that contain glycol ether solvents, which can be harmful.
Therefore, it’s important to use them in a well-ventilated space and follow the stain manufacturers’ safety precautions.
While water-based stains may be slightly more expensive and require more coats than oil-based ones, they are non-toxic once fully cured, making them a safer choice overall.
Consider using water-based stains if you’re concerned about reducing your exposure to toxic chemicals during the staining process.
Oil-based Wood Stain Toxicity
Oil-based wood stains contain various harmful ingredients, including petroleum, alcohol, formaldehyde, sodium hydroxide, and glycol ether.
In addition, these stains often contain acrylic or urethane binders and release high levels of volatile organic compounds (VOCs).
The main concern with these variety of wood stains is inhaling harmful vapors. However, these risks can be minimized by using the product in a well-ventilated space.
These oil based wood stains are only toxic during the application and drying process. Once the stain is fully dry and cured, it is no longer toxic.
While the stain is still wet, it should be kept away from any ignition sources, including the rag used to apply it, as it can spontaneously combust.
How Wood Stain Fumes Affect Health
Wood stains can have negative health effects on humans and animals, with the severity of the effects depending on the specific chemicals they contain and the level of exposure.
These effects can include:
Minor effects
- Eye, nose, and throat irritation
- Headaches and dizziness
- Allergic reactions
- Skin irritation
Moderate effects
- Respiratory problems
- Nausea and vomiting
Severe effects
- Damage to the central nervous system
- Seizures
- Reduced alertness
- Cancer

When using wood stains, it’s important to take precautions to protect yourself and others from toxic wood stain fumes. Here are some things you can do to reduce exposure risk:
- Wear protective gear, like non-latex gloves, safety glasses, and a mask.
- Work in a well-ventilated area.
- Keep kids and pets away from the fumes.
- Protect Your Clothing: Wear an apron to shield your clothing from accidental spills and stains. Here are some of the best woodworkers apron to choose from.
- Wash your hands thoroughly after using wood stain
- Read the label and follow the manufacturer’s instructions, including any precautions and warnings.
- Soak any rags or staining materials in water before tossing them to avoid combustion and help the environment.
- Properly dispose of wood stain and any materials you used to apply it, following the manufacturer’s instructions.
Non-toxic Wood Stain Alternatives
You can always opt for DIY wood stains to get your project done without suffering through the harsh fumes that commercial stains contain.
You can get food-safe wood stain using products like coffee, red wine, beet, turmeric, black tea, etc.
However, it’s important to note that these natural wood stains may not provide the same level of protection as traditional wood stains.
So you may need to add protective wood finishes like water-based sealers to prolong the lifespan of the natural stain.
Where possible, test these natural stains on scrap wood before coating the entire surface.
Red wine
To create a unique and non-traditional wood stain, try using red wine to achieve a reddish color.
- Dip a rag in red wine.
- Rub the wine onto the wood using the rag.
- Repeat the process until the desired color is achieved, typically requiring at least 3 coats.
Coffee stain
For a natural and inexpensive option for staining wood, try using wood stain instant coffee to create a unique and customizable finish.
- Brew instant coffee three to four times the normal strength.
- Apply coffee stain to the wood using a brush or cloth.
- Allow the coffee stain to sit on the wood for a while. The longer it sits, the darker the wood will become.
- Wipe off the excess coffee stain with a clean cloth.
- Allow the wood to dry completely. Reapply additional coats for a darker stain finish.
Black tea
Black tea is another popular natural wood stain, but it is significantly lighter in color compared to coffee stain. That means it’s harder to get a dark color on the wood.
- Brew a strong cup of black tea.
- Dip a rag into the tea.
- Apply the wood stain tea to the wood in the direction of the grain.
- Allow the tea to sit on the wood for the desired amount of time before wiping off any excess.
- Allow the wood to dry completely. Repeat the process as necessary.
Other natural oil finishes you can use include pure linseed or Tung oil. These are plant-based wood stains and are completely safe to use. The adulterated version of these oils can pose some threats.
Is Wood Stain Toxic After It Dries?
No. Wood stains are only toxic in liquid form during application and drying. However, the toxicity dissipates once the dangerous solvents evaporate and the stain dries and cures completely.
The curing process can take anywhere from 3 to 30 days, depending on the brand and type of wood stain.
During the drying process, volatile organic compounds (VOCs) are released into the air. That’s why it’s imperative to ensure that the area is well-ventilated to prevent wood stain poisoning.
Most wood stains are not labeled food safe due to a lack of testing in this regard. However, they are manufactured to comply with the Food and Drug Administration’s (FDA) regulations for food safety.
Whenever wood stain food safety is concerned, avoid using traditional synthetic-based stains.
