If the claim is “This burns weeds in one day and they never grow again,” that’s misleading.
Some treatments can make weeds wilt or turn brown within a day, especially young weeds. But contact treatments such as vinegar or heat generally affect the foliage they touch and may not kill established roots, so perennial weeds can grow back.

For longer-lasting control, removing the roots when practical, repeated removal of new growth, and using mulch to suppress new seedlings are more reliable approaches.

Also, be careful with concentrated “weed-killing vinegar”: horticultural-strength acetic acid can cause serious skin and eye injuries, and household vinegar isn’t equivalent to these products.
