Yes, Vinegar Actually Works on Weeds—Here's the Catch
The vinegar in your pantry won't cut it. But industrial-strength 30% vinegar? That's a completely different story. Here's what actually works for stinknet and invasive weeds.
Get 30% Industrial Vinegar →Good News: Industrial Vinegar Really Does Work
If you've tried household vinegar on weeds and been disappointed, you're not alone—5% just isn't strong enough. But 30% industrial vinegar is a completely different story. It's the concentration that agricultural professionals actually use, and it delivers real results on young weeds and hardscape areas.
When desert rains hit and stinknet (globe chamomile) explodes across your property, you need something that works—not another disappointment. The internet is full of "vinegar weed killer" advice, but most of it leaves out the critical detail: concentration matters enormously.
This Is the Concentration That Actually Works
Agricultural research and real-world experience point to 20-30% as the threshold where acetic acid starts delivering meaningful weed desiccation. Below that? Disappointing results. At 30%? Professional-grade performance.

6× the Concentration
At 30%, you're working with six times the acetic acid of household vinegar. That's the difference between browning a leaf tip and actually desiccating the plant.
Fast, Visible Results
Contact desiccation means you'll see browning within hours—not days. Full results typically visible in 24-48 hours on young weeds.
Perfect for Annuals
Young annual weeds like stinknet are ideal targets. Their limited root reserves make them highly susceptible to contact desiccation.
Manageable Safety
Unlike glacial acetic acid, 30% vinegar is workable with standard PPE—safety glasses, chemical gloves, long sleeves. Serious but not industrial-hazmat level.
The Concentration Spectrum: What Works (And What Doesn't)
Not all "vinegar" is created equal. Here's the honest breakdown:
⛔ Why We Don't Recommend Glacial Acetic Acid for Weeds
Some people think "stronger = better" and reach for glacial acetic acid (99%+). This is a mistake. It causes severe chemical burns, serious eye damage, and is flammable. For weed control, 30% gets the job done without the extreme hazard profile. Save glacial for legitimate industrial/lab applications.
Best Uses for 30% Industrial Vinegar
Industrial vinegar shines in specific situations. Here's where you'll get the best results:
Driveways & Gravel
Perfect for hardscape areas where you want complete vegetation removal. No desirable plants to protect means ideal results.
Sidewalks & Patios
Targeted spot treatment for weeds in concrete joints, brick gaps, and paver cracks. Precision application = great outcomes.
Young Annual Weeds
Stinknet, puncturevine, and other annuals are most vulnerable when small. Early treatment = best results.
Fence Lines & Edges
Property borders where you need clean lines. Non-selective action is actually an advantage here.
How to Use 30% Industrial Vinegar Effectively
5 Steps to Success
Get the best results from your industrial vinegar application
Act Early—Small Weeds Are Easier
Target weeds when they're young and small (under 4 inches). Young plants have limited root reserves and are much more susceptible to contact desiccation.
Choose the Right Day
Apply on a sunny, calm day. Avoid wind (prevents drift to desirable plants) and make sure no rain is expected for 24 hours. Sunshine enhances the desiccation effect.
Wear Proper PPE
30% vinegar requires respect: safety glasses or goggles, chemical-resistant gloves, long sleeves. It can cause burns—take precautions seriously.
Spray to Wet—Complete Coverage Matters
This is a contact herbicide—it only kills what it touches. Spray until all plant surfaces are thoroughly wet. Missed spots = missed weeds.
Plan for Follow-Up
Seeds persist in soil for years. One treatment won't end your problem forever—but consistent early treatment each season will get it under control.

Safety Guidelines for 30% Vinegar
Industrial vinegar requires respect—but it's completely manageable with proper precautions:
- Eye protection: Safety glasses or chemical splash goggles
- Hand protection: Chemical-resistant gloves (not cloth garden gloves)
- Skin protection: Long sleeves, long pants, closed-toe shoes
- Ventilation: Use outdoors; avoid breathing concentrated vapors
- First aid: If contact occurs, rinse immediately with plenty of water
Bottom line: With standard PPE, 30% vinegar is completely workable for outdoor vegetation management. Just don't treat it like the stuff in your salad.
What About Stinknet Specifically?
Stinknet (globe chamomile) is the invasive annual that's taken over the Southwest after wet winters. Here's the good news: as an annual weed, it's actually a good candidate for vinegar-based control—if you time it right.
Keys to stinknet success:
- Catch it early: Young stinknet (under 4 inches) is highly susceptible
- Use 30%: This concentration delivers results on stinknet
- Focus on hardscape: Gravel, driveways, and paths are ideal
- Be persistent: Seeds last for years; plan for multi-season management
- Prevent spread: Clean boots/tools/vehicles to avoid transporting seeds
Frequently Asked Questions
Does vinegar really kill weeds?
Yes—but concentration matters enormously. Household vinegar (5%) rarely delivers satisfying results. Industrial vinegar at 20-30% is where real weed control begins. It works as a contact desiccant, destroying plant cell membranes on contact.
Why 30% instead of stronger?
30% hits the sweet spot: strong enough to deliver professional results, but with a manageable safety profile. Jumping to glacial acetic acid (99%) dramatically increases hazards without proportional benefit.
Will it kill weeds permanently?
It kills what it contacts—but it's not systemic (doesn't travel to roots). Young annuals often die completely. Established perennials may regrow. Think of it as one tool in your management plan.
Is it safe for my yard?
Industrial vinegar is non-selective—it damages any plant it touches. It's ideal for hardscape areas where you want everything gone. In mixed landscapes, use targeted application and protect desirable plants.
What size should I order?
For small areas (patios, walkways), a gallon may suffice. For larger properties or ongoing management, 5-gallon containers offer better value. Commercial operations often use 55-gallon drums.
