That headline is likely an exaggerated or misleading claim.
“Burns weeds in 1 day” can happen with contact herbicides (including vinegar-based sprays), which may quickly brown or wilt the visible parts of a weed. However, “they NEVER grow again” is rarely true. Many weeds regrow from surviving roots, rhizomes, tubers, or seeds already in the soil.
A more accurate version would be:
This homemade weed killer can dry out many weeds within 24 hours—but stubborn weeds may require repeat treatments.
Or, if you’re writing a social media hook:
These common kitchen ingredients can make weeds wilt in a day. Here’s how it works.
If you’re creating content, it’s generally best to avoid absolute claims like “never” unless you have strong evidence to support them.
