This product contains a 20% acetic acid concentration, making it four times stronger than standard household vinegar, which typically contains only 5%. This higher concentration is necessary to effectively burn down weeds upon contact.

Yes, this is a non-selective herbicide, meaning it will damage or kill any green vegetation it touches. Use caution when spraying near desirable plants and avoid applying on windy days to prevent drift.

While this formula is glyphosate-free and derived from corn, it is still a potent acid that can cause skin and eye irritation. Keep pets and children away from the treated area until the spray has completely dried.

This is a contact herbicide, meaning it works by rapidly dehydrating the foliage it touches. While it is highly effective at killing the visible plant, it may not always reach deep into established root systems, so some hardy weeds might require a second application.

Because it works on contact, you will typically see wilting and browning of the weeds within a few hours of application, especially on a sunny, warm day.
