Insta-Flo Crystals Drain Cleaner 2 lb, Pack of 6

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 hours or overnight for results. Insta-Flo will liquefy hair and grease in less than 60 seconds. Hot water activates Insta-Flo's dry, odorless crystals. Within 60 seconds, even the most difficult drain blockage in a small drain is cleared. Insta-Flo's non-acid formula will not harm fine fixtures, porcelain, chrome trim, polished brass, plastic or metal pipes.
