ComStar 1 lb. Pure Lye Drain Opener

ComStar Pure Lye is an industrial-strength, powerful formula designed to clear clogged and slow-running drains, grease traps, septic systems, and root growth. Made from ninety-nine percent pure sodium hydroxide beads, this non-acidic drain opener sinks through standing water directly to the source of the blockage for fast, effective clearing without producing odors or harmful fumes. This biodegradable formula is safe for use on fine plumbing fixtures, chrome trim, metal pipes, and plastic piping systems. It will not harm septic tanks or cesspools and can enhance active bacteria growth in septic systems when used regularly, making it ideal for residential, commercial, school, hospital, and restaurant applications.
