That kind of claim is almost always marketing exaggeration.
There is no safe, single homemade method that “burns weeds in 1 day and they never grow again” without consequences. What usually gets promoted in those videos is one of these:
What they’re probably referring to
- Boiling water or flame torch → kills visible leaves quickly, but roots often survive.
- Vinegar + salt + dish soap mix → can scorch leaves fast, but:
- It does not reliably kill roots
- Salt can damage soil for months/years, making nothing grow there
- Chemical herbicides → some do work systemically, but they still require correct use and may not guarantee permanent prevention.
The reality about weeds
Weeds are persistent because:
- Roots regrow (dandelions, grass weeds)
- Seeds stay in soil for years
- Nearby plants constantly re-seed the area
So “never grow again” is basically not realistic unless you change the environment (like mulch, landscaping fabric, paving, etc.).
Safer, effective ways to actually control weeds
If your goal is long-term results:
- Hand pulling after rain (best for deep-rooted weeds)
- Mulching (wood chips, straw) → blocks light so seeds can’t sprout
- Boiling water (good for cracks in pavement)
- Targeted herbicides (used carefully, only where needed)
- Regular trimming before weeds seed
Bottom line
Quick “burn-it-and-it’s-gone forever” hacks usually either:
- only kill the top part, or
- damage the soil long-term, or
- simply don’t work as advertised.
If you want, tell me where your weeds are growing (garden, driveway, lawn), and I’ll suggest the most effective method for that exact situation.
