That grass stain on the knee, the red wine splash on a favorite shirt, or the mysterious yellow ring around a collar — these laundry battles are fought in the wash cycle, and your standard detergent alone often loses. A dedicated stain-fighting additive is the tactical advantage your washing machine needs to break down and lift the organic and inorganic bonds that lock discoloration into fabric fibers.
I’m Mo Mahin — the founder and writer behind Furric. I’ve spent years digging through chemical formulation data, enzyme performance metrics, oxygen bleach activation temperatures, and thousands of aggregated owner reports to identify exactly which laundry additives deliver on their stain-removal promises without damaging your fabrics or machine.
Below, I break down the top-performing options across different stain types and wash habits so you can confidently pick the best laundry additive for stains that fits your specific laundry challenges and budget.
How To Choose The Best Laundry Additive For Stains
Not all stain removers are created equal. The right choice depends on whether you are fighting protein-based stains (blood, grass, sweat), oil-based stains (grease, makeup), or tannin stains (coffee, wine, berries). Here are the three critical factors to consider before you buy.
Enzyme Power vs. Oxygen Bleach Action
Enzyme-based additives use protease, lipase, and amylase to break down specific stain molecules at the molecular level. They work best in warm water and on organic stains. Oxygen bleach additives (sodium percarbonate) release hydrogen peroxide when dissolved in water, making them excellent for whitening whites and removing set-in colored stains. Many premium formulations combine both for a broad-spectrum approach.
Form: Pre-Treatment Spray vs. In-Wash Booster
A trigger spray allows you to target a stain directly before the wash cycle, giving the enzymes time to work — ideal for immediate treatment of fresh spills. In-wash powders or liquids distribute through the entire load, boosting the detergent’s power on all fabrics simultaneously. The most effective stain-fighting routines use a pre-treatment spray followed by an in-wash booster for the same load.
Fabric and Machine Compatibility
Check that the additive is safe for your machine type (HE vs. standard) and fabric types (delicates, activewear, cotton). Chlorine-free oxygen additives are color-safe, while some enzyme pre-treatments are aggressive on silk and wool. Always verify cold-water effectiveness if you primarily do cold washes to save energy.

In‑Depth Reviews
1. Soilove Laundry Stain Remover Liquid – 6 Bottles (16oz)
Soilove is built around a triple-action enzyme formula that chemically targets proteins, fats, and starches — the molecular building blocks of tough stains like blood, grease, ink, grass, and food spills. The liquid clings to fabric fibers and penetrates deeply, lifting the stain so it can be washed away rather than just diluted. Users working in painter trades report it handles washable paint and ink without pre-scrubbing, which speaks to its aggressive enzyme activity.
This value pack includes six 16-ounce bottles, making it a bulk solution for households that deal with heavy soiling regularly. It works in both hot and cold water and is safe for standard and HE machines when used as a pre-treatment. Several long-term users mention it has been their go-to for years, noting its consistency on biological stains that oxygen bleach alone fails to remove completely.
The enzyme formula does have a notable scent — not unpleasant, but present enough that sensitive noses might notice it during application. It is also susceptible to freezing; if left in a cold car, the bottles can crack, so store it indoors. For anyone needing an aggressive, reliable pre-treatment that tackles the full spectrum of organic stains, this is a top-tier choice.
Why we love it
- Triple-enzyme formula attacks protein, fat, and starch stains effectively.
- Six-bottle pack provides long-term supply for heavy-duty laundry needs.
- Works as a pre-soak or direct spray for flexible pre-treatment.
- Safe for colors and HE machines when used as directed.
Good to know
- Has a distinct chemical scent that some may find strong.
- Liquid can freeze and crack bottles if left in cold environments.
2. OxiClean Triple Action White Revive Laundry Whitener and Stain Remover Powder, 4 lbs
OxiClean White Revive uses oxygen bleach technology — sodium percarbonate that releases hydrogen peroxide when dissolved — to break down colored stains and lift them from fabric without the harshness of chlorine bleach. The label claims three times the whitening power compared to the leading value detergent alone, which is a direct result of the oxygen molecules oxidizing stain pigments. Regular users report dramatic results on white socks, shirts, and towels, restoring them to near-new brightness.
The powder dissolves well in both hot and cold water, making it compatible with any wash temperature. It is explicitly safe for colors as well as whites, and it is chlorine-free, so it will not cause yellowing on synthetic fabrics over time. The 4-pound resealable pouch is designed for easy storage and dispensing, and the formula works equally well as an in-wash booster or as a pre-soak for heavily stained items.
Some users note that for the most stubborn set-in stains, an overnight soak yields the best results — a quick wash cycle may not give the oxygen enough contact time. The scent is described as clean and non-overpowering, and it does not leave a residue on clothes. For anyone focused on restoring white brightness and tackling general tough stains with oxygen power, this is the most effective powder option.
Why we love it
- Oxygen bleach formula whitens whites without chlorine damage.
- Resealable pouch stores easily and keeps powder dry.
- Works effectively in cold water for energy-saving washes.
- Safe for use on both whites and colors in HE machines.
Good to know
- Best results require soaking for several hours on heavy stains.
- Powder may clump if exposed to humidity over time.
3. Biz Laundry Detergent Powder, Stain and Odor Eliminator, 37.5 Ounce
Biz powder combines enzymes, oxygen bleach, and whitening agents into a single concentrated booster that you add to every load to enhance your detergent’s performance. The enzyme blend specifically includes lipase, which breaks down fatty stains like chocolate and grease, making it more effective on those stains than straight oxygen bleach alone. Users on social media have rediscovered this product as a viral laundry stripping agent for restoring stained and old clothes.
It can be used three ways: as a in-wash powder booster, as a pre-soak for heavily soiled items, or mixed with water into a paste for direct pre-treatment. The unscented formula means no added fragrance, which is helpful for households sensitive to perfumes. It works across all water temperatures and is safe for both standard and HE machines at the recommended dosage levels.
Note that the price per ounce on Amazon can be significantly higher than what some grocery stores charge, so it pays to compare local pricing before buying in bulk here. It is also unscented, which some users prefer for fragrance-free laundry but others may miss a fresh scent. For a versatile, enzyme-rich booster that works especially well on food and body oil stains, Biz is a proven, budget-friendly option.
Why we love it
- Contains lipase enzyme for breaking down fatty stains effectively.
- Three application methods: booster, pre-soak, or pre-treatment paste.
- Unscented formula suitable for sensitive skin households.
- Viral laundry stripping method restores dingy fabrics.
Good to know
- Amazon price can be higher than local grocery store pricing.
- No added fresh scent — leaves clothes smelling neutral.
4. Spray-N-Wash 22 oz. Trigger Spray Bottle Laundry Stain Remover
Spray-N-Wash is a concentrated liquid stain remover delivered via a trigger spray bottle, allowing you to target specific stains with precision before the wash cycle. The formula is fragrance-free and environmentally conscious, which makes it suitable for households that avoid strong chemical scents. Multiple long-term users report spraying stains the night before and washing after 12 hours with excellent results on children’s clothing and everyday messes.
This is a no-nonsense pre-treatment that relies on concentrated cleaning agents rather than enzymes, so it performs well across a broad range of stain types without the need for specific water temperatures. The 22-ounce bottle is compact enough to keep near the laundry basket for immediate treatment of fresh spills. It is safe for all fabrics and machines when used as directed.
The unscented nature means there is no masking fragrance to cover residual odors, so you rely entirely on the washing process. Some users may prefer a product with a built-in scent boost. For a straightforward, effective pre-treatment spray that works on old stains with extended dwell time, this is a reliable choice for households looking for simplicity.
Why we love it
- Trigger spray allows precise application to individual stains.
- Concentrated formula works well with overnight pre-treatment.
- Fragrance-free for scent-sensitive households.
- Safe for all washable fabrics and machine types.
Good to know
- No enzymes or oxygen bleach — relies on concentrated surfactants.
- Does not add any fresh scent to the laundry load.
5. Lysol Laundry Sanitizer Additive, Crisp Linen, 90oz
Lysol Laundry Sanitizer is designed as an in-wash additive that kills 99.9% of bacteria (Staphylococcus aureus and Klebsiella pneumonia) on laundry, addressing the root cause of persistent odors rather than just masking them with fragrances. It is added to the fabric softener drawer and works in cold water, making it ideal for activewear, gym clothes, and towels that develop bacterial smells over time. Users with football gear, wrestling uniforms, and other heavily soiled sports equipment report it eliminates odors that standard detergents leave behind.
The formula is a bleach alternative, so it is safe on colors and whites alike, and it does not cause fading or fabric damage. The Crisp Linen scent is clean and fresh but not overpowering — it balances odors effectively. The 90-ounce bottle provides many washes, with users noting that a single capful per load is sufficient for most loads.
This product does not function primarily as a stain remover; it is a sanitizing additive. While it can help with odor-causing bacteria that contribute to stain retention, it will not break down visible stains like grass or blood on its own. Pair it with a dedicated stain remover for a complete laundry solution. For households where odor is the primary issue, this is the most effective option.
Why we love it
- Kills odor-causing bacteria at the source, not just masks smell.
- Safe on colors and works effectively in cold water.
- Gentle on activewear and delicate synthetic fabrics.
- Large 90-ounce bottle offers long-term value per wash.
Good to know
- Primarily a sanitizer, not a direct stain removal treatment.
- Best used in combination with a dedicated stain remover.
