Critical Safety Precautions and Warnings

Isopropyl alcohol is flammable and can be an irritant. Treat this homemade herbicide with respect.

1. Personal Protective Equipment (PPE)

Always wear gloves and safety goggles when mixing and spraying. Consider a mask if spraying in an enclosed area or if you are sensitive to fumes. Wear long sleeves and pants to protect your skin.

2. Flammability Hazard

Isopropyl alcohol and its vapors are highly flammable. Do not mix, store, or use near open flames, sparks, hot surfaces, or electrical equipment. Do not smoke during the process. Allow sprayed areas to dry completely before exposing them to any potential ignition source.

3. Environmental and Plant Safety

This solution will kill any plant it touches. Be absolutely certain of your aim. Avoid spraying on windy days (>5 mph). Do not use it as a soil drench, as it can harm soil microbiology. It is best suited for non-vegetated areas like driveways, walkways, stone paths, and fence lines.

4. Storage and Disposal

Store the mixed solution in its clearly labeled spray bottle, out of reach of children and pets, in a cool, dark place away from direct sunlight and heat sources. For disposal, small amounts of unused solution can be diluted with large amounts of water and poured down the drain. Never pour concentrated alcohol or large quantities of mix onto soil or into storm drains.
