How It Works

Four steps. A few minutes. Done.

1. Prep — remove as much standing water as possible.
2. Pour — empty one entire ZYNOR sachet into a dry drain.
3. Activate — immediately add 1 cup of hot (not boiling) water. Wait 10–15 minutes.
4. Rinse — flush thoroughly with warm water for 5–10 minutes.

For a stubborn clog you can wait up to 30 minutes before rinsing. For upkeep, one packet a month keeps clogs from ever starting.

What ZYNOR dissolves

Hair, pet fur, grease, soap scum and everyday organic buildup — the things that actually clog kitchen and bathroom drains. It won't dissolve solid objects, plastic or hard mineral scale.

Where to use it

Kitchen sinks, showers and tubs, bathroom sinks, and monthly maintenance across every drain in the home.

Safe for your plumbing

ZYNOR is safe for PVC and standard household drain lines and won't upset a healthy septic system. No chlorine, no aluminum, no phosphates. Don't use it on aluminum fittings.

DANGER: Contains sodium hydroxide (caustic soda). Causes severe burns to eyes and skin; may be fatal if swallowed. Wear gloves, avoid contact with skin, eyes, mouth and clothing, and never mix with other drain cleaners, bleach or acids. Keep out of reach of children and pets. Read the full label before use. Poison Control: 800-222-1222.
