One Shot Instant Drain Cleaner 1 Litre

One Shot Instant Drain Cleaner is a powerful liquid formulated to clear blocked drains and keep water flowing freely. Use only as directed. Before treatment, remove as much standing water as possible. Always pour very slowly and directly into the drain. For sink drains, use about 125 ml initially, allow to stand for 5 minutes, then carefully flush with cold water; repeat if needed. For toilets and floor drains, use about 250 ml and follow the same process. For prevention, add 100 ml per month to each drain. For best results, treat early in the morning. Produced by Angel, this professional and trade use product is designed for home maintenance and facilities care where quick, reliable performance matters. Keep out of the reach of children and follow all on‑pack safety precautions. The front panel notes UN APPROVED CERTIFICATION No: 4G/Y2/S/25/GB/7006. Choose this measured, step‑by‑step solution to restore flow and maintain pipes with confidence when routine plunging is not enough.
