IS-600 Drain Cleaner, Solid, White, Odorless, 6 lb Bottle

The usual cause for sluggish drains is a build-up of grease, hair, soap scum or bath oils. Most drain cleaners require 2 to 6 hr (or overnight) for results. Insta-Flo will liquefy hair and grease in less than 60 secs. HOT water activates Insta-Flo's dry, odorless crystals. Within 60 sec the drain is clear even on the most difficult drain blockage. Insta-Flo is also great for sewer lines, grease traps and septic systems. Insta-Flo non-acid formula will not harm fine fixtures, porcelain, chrome trim, polished brass, plastic or metal pipes.
