The 6 Best Enzyme Laundry Detergents (And Why It’s So Great)

Regular detergents clean the easy stuff. Oil, dirt, soap scum, everyday grime.

What they can’t handle is the organic stuff.

Blood, grass, food, sweat, the dog’s accident on the comforter. That’s where enzymes come in.

Enzyme detergents add biological catalysts that break down specific stain types. There are six enzymes used in modern laundry detergents, and each one targets a different kind of mess:

• Protease attacks protein stains like blood, sweat, dairy, and eggs.
• Amylase targets carbohydrate and starch stains (pasta sauce, gravy, baby food).
• Cellulase breaks down tough organic fibers in stains.
• Lipase handles fats and oil stains.
• Mannanase dissolves food stains with gums or thickeners.
• Pectinase goes after fruit and jam stains.

Below are the six best enzyme laundry detergents I recommend, from specialists to everyday workhorses.

6 Great Enzyme Laundry Detergents

Dirty Labs Bio Enzyme Laundry Detergent

Dirty Labs is the boutique pick.

They built their formula around five of the six enzyme types (protease, amylase, cellulase, mannanase, and pectinase), intentionally leaving out lipase.

That makes it excellent on organic and food stains but not the pick for grease-heavy laundry.

The 21.6 oz aluminum refill bottle does 80 loads and the packaging is 100% recyclable.

This is a direct-to-consumer brand sold from their own website, not Amazon, so there’s no purchase link here.

Worth knowing about if eco-credentials matter to you.

Presto! Laundry Detergent

Amazon’s own enzyme detergent. Three enzymes (protease, amylase, mannanase) cover protein, starch, and food stains at a price that’s genuinely hard to beat.

It’s not the most powerful on this list.

For general everyday laundry with the occasional stain, it handles the job.

Works in both standard and HE machines, which matters if you move between apartments or have mixed machines at home.

Rockin' Green Activewear Detergent

This is the one for gym clothes, running kit, and anything that comes out of the hamper smelling like sweat you can’t wash out. Plant-based formula, enzyme-powered, and specifically designed to target the proteins and oils that performance fabrics hold onto.

Super concentrated. A 45 oz package does 90 loads.

Unscented, so the cleaned garment actually smells neutral instead of competing with your body wash.

Biokleen Natural Cold Water Laundry Detergent

Biokleen is the cold-water specialist.

Most enzyme detergents still work better in warm water. This one is formulated specifically for cold.

Cold cleaning saves energy and is safer on fabrics that shrink or fade in heat.

Plant-based enzymes plus separate odor-removal additives. Works on whites and colors without fading.

No phosphates, ammonia, or optical brighteners, which keeps it safe for sensitive skin.

Persil Proclean Liquid Laundry Detergent

The trusted one. Persil has been making detergent in Germany since 1907 and they know their chemistry.

ProClean is their enzyme-boosted line, 2X concentrated so you use less per load without losing cleaning power.

An 82.5 oz bottle gives you 110 loads. This is what I’d buy for a household dealing with real stains on the regular.

Kids’ clothes, work uniforms, the comforter that needs actual cleaning. Once you do the math on loads-per-dollar, it’s also one of the cheapest options on this list.

All Stain Lifters Free & Clear

The sensitive-skin pick. No dyes, no fragrance, no optical brighteners.

If someone in the house reacts to regular detergent, this is the clean switch.

Don’t mistake “free and clear” for weak.

This is still enzyme-powered, 2X concentrated, and pulls off real cleaning. 110 loads from an 82.5 oz bottle.

Tough enough for pet bedding and kids’ clothes without triggering rashes.

Merits of Using Enzyme-Based Laundry Detergents

Enzymes change what laundry is doing.

Regular detergents rely on surfactants and heat to break up dirt.

Enzyme detergents use biological catalysts that target specific stain types, which opens up four practical advantages.

Eliminates the Need for Hot Water for Stain Removal

Hot water is the traditional stain-removal trick. It works, but it also eats energy, fades colors, and shrinks fabrics that can’t handle the heat.

Enzymes work at cold and warm temperatures just as well.

You can run the normal load at 30°C, or even cold, and still lift stains that used to need a hot cycle.

Lower energy bills, less fabric damage.

Care for the Delicate Clothes

Wool, silk, denim, and dyed cotton all lose something when washed hot. Shrinking, bleeding dye, or losing shape.

Enzyme detergents don’t need heat to do their job, so you can run the cold cycle on everything without sacrificing clean.

Reduction in the Use of Phosphate Salts and Synthetic Surfactants

Phosphates and harsh synthetic surfactants work, but they don’t rinse out of waterways. Many countries have banned or heavily restricted them.

Enzyme formulations replace some of that chemistry with biology. Cleaner rinse water, less environmental impact.

More Cost-Effective

Enzyme detergents are typically more concentrated than regular detergent, so you use less per load. Over the life of a bottle, that’s 50 to 100 percent more washes for roughly the same price.

Compare the loads-per-bottle on any of the options above against the regular detergent you currently buy and you’ll see the math.

How to Use Enzymatic Detergents

Enzyme detergents work best as a pretreatment on set-in stains. Here’s the routine:

• Fill a basin or the top-loader with warm (not hot) water.
• Add the recommended dose of enzyme detergent.
• Submerge the stained garment completely.
• Agitate gently so the detergent reaches everything.
• Soak for at least 2 hours. Overnight for stubborn stains.
• Drain, add your normal detergent dose, and run the regular cycle.

For fresh stains, you can skip the soak and just run the wash with enzyme detergent as your main detergent. They work fine as a one-shot wash.

Read the garment care tag first. Enzymes are fine on most fabrics, but a few vintage or specialty fabrics don’t tolerate them well.

One caveat: enzymes need warm water and time to work, which is why they don't translate well to a hotel sink rinse. If you travel often, washing clothes while traveling covers what actually works on the road when enzymes aren't an option.

Frequently Asked Questions

At What PH Do Most Enzymes Function Best in Detergents?

Most laundry enzymes work best in slightly alkaline water, between pH 7 and pH 10. Each enzyme has its own optimal range inside that band, and detergent manufacturers formulate their products to hit those conditions once diluted in wash water.

You don’t need to test your water. If you’re using the detergent as directed, the chemistry handles itself.

When Were Enzymes First Used in Laundry Detergents?

The first commercial enzyme detergent launched in the 1960s, using protease to break down protein stains. Enzyme use grew slowly until the 1980s, when genetic engineering made it cheap to produce laundry-grade enzymes in bulk.

Since then, enzymes have become standard ingredients in almost every major detergent brand.

What Are Enzymatic Stains?

Enzymatic stains are organic.

Blood, sweat, grass, food, urine, pet accidents, protein-based spills like milk or eggs.

These are the stains regular detergent struggles with because the molecules need to be broken apart, not just washed away.

For a specific application, see my guide on removing urine stains from clothes and mattresses. Enzyme detergents are particularly effective there.
