How to Make DIY Weed Killer: Step-by-Step 🧪
1. Mix the Ingredients
Pour **1 gallon white vinegar**, **2 cups salt**, and **¼ cup Dawn dish soap** into a large container or spray bottle.
Shake well to combine. Let sit for a few minutes until fully mixed.
2. Apply the Spray
Spray the solution directly on the weeds, **soaking the entire plant**—leaves, stems, and base.
3. Let It Work
Let the mixture sit **for 24 hours** in full sun. You’ll start seeing results within hours, with most weeds browned and wilted by the next day.
Pro Tip:
Apply during a **dry afternoon** when weeds are not wet with morning dew or rain for best results.

Why This Formula Works 🌞
Vinegar (Acetic Acid)
Breaks down plant cell walls, dehydrating the weed quickly. The higher the acidity, the faster it works.
Salt
Draws moisture from the plant and soil, preventing regrowth. Use table salt for non-garden areas, Epsom salt for safer application around soil.
Dish Soap
Acts as a surfactant, helping the solution stick to leaves and penetrate the plant faster.

10 Frequently Asked Questions (FAQs) ❓
- Is this safe around pets?
Yes, once dry. Keep pets away while the solution is still wet to avoid irritation. - Can I use this in my vegetable garden?
Only use on paths or between rows. Avoid direct contact with edible plants, as vinegar and salt may affect soil health. - Will it kill grass?
Yes. This solution is non-selective and will kill any plant it touches—use carefully around lawns. - What type of vinegar is best?
White vinegar with at least 5% acetic acid is effective. For stronger results, use horticultural vinegar (20% acetic acid). - How long before I see results?
In full sun, you’ll start to see wilting in a few hours. Most weeds die within 24–48 hours. - Can I store the mixture?
Yes—store in a cool, dark place with the lid tightly sealed. Shake well before each use. - What’s the difference between Epsom and table salt?
Epsom salt (magnesium sulfate) is less harmful to soil. Table salt (sodium chloride) is stronger but can damage soil microbiomes. - Does this work on dandelions?
Yes—it kills the visible part, but repeat applications may be needed to destroy deep roots. - Should I pull weeds after they die?
Yes. Removing dead weeds prevents reseeding and keeps your space tidy. - Can I spray this before it rains?
No—rain will dilute and wash away the solution before it works. Spray during dry weather.
