“Burnout” (25% acetic acid) carries a DANGER label: corrosive, causes severe eye/skin burns, respiratory damage if inhaled. Household vinegar (5%) kills only tiny annual seedlings; 10–20% acetic acid gives 80–100% kill of small annuals but does not control established perennials. Glyphosate remains far more effective for deep-rooted weeds. For a dog-sensitive household, mechanical removal is safest.
