Hercules, 20-305, Drain and Waste System Cleaner, Can, 1 qt, Liquid, Yellow to light amber liquid, Odorless

20-305 Hercules® Sizzle™ Drain and Waste System Cleaner – 1 Quart

Hercules® Sizzle™ is a chemically reactive, acid-based cleaner formulated for the removal of mineral scale and inorganic deposits within drain, waste, and hydronic systems. Its triple-action composition of virgin hydrochloric acid, corrosion inhibitors, and foam suppressant ensures rapid dissolution of carbonate, sulfate, oxide, and phosphate residues that restrict flow and reduce thermal transfer efficiency. Designed for use on ferrous and non-ferrous metals, Sizzle™ restores system performance in heating, plumbing, and process applications requiring high-strength descaling.

Professional Notes

Sizzle™ is intended for professional descaling operations where mineral and inorganic build-up reduces system flow or heat transfer efficiency. The hydrochloric acid-based chemistry provides aggressive scale dissolution while integrated inhibitors limit corrosion to underlying metal surfaces. The product’s foam suppressant stabilizes reaction control and minimizes splashing during application. Suitable for use in water, waste, and process systems, Sizzle™ effectively clears internal obstructions and surface deposits on metallic fixtures and piping. Use is restricted to trained personnel following proper PPE and neutralization procedures. This formulation is not recommended for use on aluminum or in confined, unventilated areas.

Summary

The Hercules® Sizzle™ Drain and Waste System Cleaner (20-305) is a concentrated, hydrochloric acid-based descaling solution designed for professional removal of mineral deposits and inorganic residues in plumbing, mechanical, and hydronic systems. Its blend of acid strength, corrosion inhibitors, and foam control technology provides efficient restoration of flow and heat transfer efficiency across boilers, radiators, and waste systems. Engineered for precision use on iron, copper, and brass installations, Sizzle™ delivers consistent field performance for contractors maintaining or restoring fluid systems affected by scale accumulation.
