500 ml alkaline drain-clear liquid (≈ 30 % sodium hydroxide). Dissolves hair, fat and soap scum; pours through standing water. Child-resistant cap.
Formulated with 30 ± 2 % NaOH in a wetting-agent solution, the liquid attacks organic blockages and converts fats to free-flowing soap. Viscosity optimised to 150 cP so the product sinks through stagnant water and clings to pipe walls. Safe for PVC, ABS and metal plumbing when used as directed; pH (neat) > 13. Apply 250 ml, wait 15 minutes, flush with hot water. Packaged in a high-density polyethylene bottle with integrated measuring scale.
