That claim is not reliable and usually misleading clickbait.
There is no safe household method that guarantees weeds will be burned in 1 day and never grow back. Weeds are living plants with roots—if the roots survive, they regrow.
What people usually mean by this claim
1. Vinegar sprays
Acetic acid
- Burns the leaves quickly
- Often does NOT kill the roots
- Weeds commonly grow back
2. Salt mixtures
Sodium chloride
- Can kill plants temporarily
- But damages soil long-term
- Can prevent future plants from growing in that area
3. Boiling water
- Works on small weeds in cracks
- Still doesn’t guarantee permanent removal
4. Fire/flame methods
- May scorch tops of weeds
- Roots often survive underground
Reality check
- “1 day kill” usually means visible leaf damage, not full plant death
- “Never grow again” is false unless the entire root system is removed or destroyed
What actually works long-term
- Pulling weeds from the root
- Using mulch to block sunlight
- Repeating removal over time
- Carefully used herbicides when appropriate
Bottom line
These posts exaggerate simple or temporary effects to sound like miracle solutions. Real weed control takes consistency, not a one-time trick.
If you want, I can give you safe DIY methods that actually work without damaging your soil or yard.
