Is Degreaser Toxic? The Truth About Grease Cutters

📅 Updated February 2026⏱️ 5 min readNEW

TL;DR

Yes, most conventional degreasers are toxic. The chemicals that melt grease—like 2-butoxyethanol and sodium hydroxide—can also damage your lungs and burn your skin. Regular use of spray cleaners has been linked to lung function decline comparable to smoking. Switch to plant-based solvents or physical abrasion for a safer clean.

🔑 Key Findings

1

Regular use of spray cleaners can damage lungs as much as smoking a pack a day for 20 years.

2

Many 'citrus' degreasers still contain harmful glycol ethers.

3

2-Butoxyethanol, a common solvent, is linked to blood disorders and liver damage.

4

Sodium hydroxide (lye) in heavy-duty degreasers can cause permanent eye damage.

The Short Answer

Yes, most conventional degreasers are toxic. To melt through solidified grease, these products rely on powerful solvents and corrosives that don't distinguish between your stovetop and your lung tissue.

The most common offender is 2-butoxyethanol, a solvent that allows the product to penetrate grease but is also easily inhaled, entering your bloodstream where it can damage red blood cells. Heavy-duty options often add sodium hydroxide (lye), which is highly corrosive and can cause permanent eye and skin damage upon contact.

If your cleaner requires you to "use in a well-ventilated area," it's a chemical hazard, not a cleaning solution.

Why This Matters

Your lungs are taking a hit. A landmark study published in the American Journal of Respiratory and Critical Care Medicine found that regular use of spray cleaning products can cause lung function decline equivalent to smoking a pack of cigarettes a day for 20 years. The fine mist allows deep inhalation of these chemicals.

Chemical burns are real. Heavy-duty degreasers are often highly alkaline (high pH). Ingredients like sodium hydroxide can cause chemical burns within seconds of contact with skin or eyes. Unlike heat burns, you might not feel the damage immediately, allowing the chemical to penetrate deeper.

Indoor air pollution. Volatile Organic Compounds (VOCs) from degreasers linger in your kitchen air long after you wipe the counter. Are Kitchen Cleaners Safe explains how this contributes to "sick building syndrome," causing headaches, dizziness, and fatigue.

What's Actually In Degreaser?

Most "heavy duty" kitchen cleaners rely on a cocktail of solvents and caustics.

  • 2-Butoxyethanol (Butyl Cellosolve) — A solvent that dissolves grease. It is absorbed through the skin and lungs and has been linked to liver and kidney damage and blood disorders in animal studies.
  • Sodium Hydroxide — Also known as lye. It turns grease into soap (saponification) but is extremely corrosive to human tissue. Is Oven Cleaner Toxic covers this ingredient in depth.
  • Ethanolamines (MEA/DEA/TEA) — Surfactants that can trigger asthma attacks and react with other chemicals to form cancer-causing nitrosamines.
  • Alkylphenol Ethoxylates — Hormone-disrupting chemicals often found in industrial degreasers. They mimic estrogen in the body and are toxic to aquatic life.
  • Fragrance — Used to mask the harsh chemical smell. A "fragrance" label can hide hundreds of undisclosed chemicals, including phthalates. Are Fragrances In Cleaners Bad

What to Look For

Green Flags:

  • Saponified Oils — Real soap (Castile soap) cuts grease effectively without toxicity.
  • D-Limonene (with caution) — Orange peel oil is a powerful natural degreaser, though it can still irritate sensitive skin.
  • Sodium Carbonate — Washing soda provides the alkalinity needed to cut grease but is far safer than lye.
  • Hypochlorous Acid — A medical-grade disinfectant that also breaks down proteins and fats.

Red Flags:

  • "Warning" or "Danger" labels — If the bottle warns of eye damage or skin burns, believe it.
  • Glycol Ethers — Look for "butoxyethanol" or similar names.
  • High pH (>11) — Highly alkaline products are corrosive.
  • Strong Solvents — Ingredients ending in "-ol" or "-ene" often signal volatile solvents.

The Best Options

You don't need industrial solvents to clean your stovetop. Here are safer alternatives that actually work.

BrandProductVerdictWhy
Force of NatureMulti-Purpose CleanerUses electricity to turn salt/water/vinegar into a powerful cleaner.
Branch BasicsConcentratePlant-based formula that cuts grease surprisingly well.
Bon AmiPowder CleanserUses physical abrasion (feldspar) to scrub grease away safely.
Simple GreenAll-Purpose⚠️Better than some, but contains colorants and undisclosed fragrance.
Easy-OffHeavy Duty Degreaser🚫Contains lye and harsh solvents. Rated F by EWG.
ZepCitrus Degreaser🚫Industrial strength often means industrial toxicity.

The Bottom Line

1. Ditch the spray solvents. If you can smell it, you're inhaling it.

2. Use physical abrasion. A good scrub brush or Bon Ami powder removes grease mechanically, reducing the need for harsh chemicals.

3. Go truly non-toxic. Safest Kitchen Cleaner options like Force of Nature or Branch Basics handle 90% of kitchen grease safely.

4. DIY for tough spots. A paste of baking soda and dish soap left to sit for 15 minutes works wonders on baked-on grime.

FAQ

Is Dawn Powerwash toxic?

Caution. While convenient, it uses alcohol and solvents to spray continuously. It is rated D by the EWG for environmental and respiratory concerns. It's safer than Easy-Off, but not "clean." Is Dawn Dish Soap Toxic

Is "Orange" or "Citrus" degreaser safe?

Depends. Natural orange oil (d-limonene) is a safe solvent, but it is a skin irritant. However, many "citrus" cleaners just add an orange scent to a standard toxic chemical base. Always check the ingredient list.

Can I use vinegar as a degreaser?

Not really. Vinegar is an acid, and grease is acidic/neutral. You need an alkaline (base) cleaner to cut grease. Baking soda or washing soda are better natural degreasers than vinegar. Does Vinegar Clean Glass
