A glyphosate-free, OMRI-listed 20% acetic-acid burndown that wilts young weeds within hours in sun, leaves no soil residual, and works in cracks and driveways. Far stronger than kitchen vinegar, so use it safely: 20% acetic acid is corrosive and irritates eyes, skin and lungs, so wear goggles and gloves; it is contact-only, often sparing perennial roots so weeds regrow.
Pros
- Glyphosate-free, OMRI-listed burndown that visibly wilts weeds within hours in sun
- No soil-residual activity, so treated areas can be replanted relatively soon
- Effective on young annual weeds in cracks, driveways, and gravel
Cons
- 20% vinegar is corrosive — it can cause serious eye and skin irritation, so goggles and gloves are required (far stronger than kitchen vinegar)
- Non-selective and contact-only: it burns tops but often doesn't kill established perennial roots, so weeds regrow and need repeat sprays
- Works best in hot, sunny weather; can damage any green plant it drifts onto

Frequently Asked Questions
- Does Green Gobbler vinegar weed killer actually work?
- On young annual weeds in sun, yes - it visibly wilts them within hours and is effective in cracks, driveways and gravel. The honest limit is that it is contact-only: it burns the tops but often does not kill established perennial roots, so those weeds regrow and need repeat sprays.
- Is 20% vinegar the same as kitchen vinegar?
- No, and treating it that way is dangerous. At 20% acetic acid it is roughly four times the strength of household vinegar and is corrosive - it can cause serious eye and skin irritation. Goggles and gloves are required, not optional.
- Can you replant after using it?
- Relatively soon, yes. It has no soil-residual activity, which is one of its genuine advantages over residual herbicides. It is also non-selective though, so it will damage any green plant it drifts onto.
- When does it work best?
- In hot, sunny weather - heat and sunlight drive the burndown. Applying on a cool, overcast day gives noticeably weaker results. It is OMRI listed and glyphosate-free, at about $25 for a ready-to-use gallon.
