Drain and Sewer Cleaner/Maintainer. 12/32 oz./cs. includes gloves.
Bloc-Aid is a bright red, ready-to-use, non-acid, liquid drain and sewer cleaner plus maintainer. A small amount of Bloc-Aid used regu-larly in free-flowing drains will help prevent common sludge build-ups of grease, fats, paper, tobacco, soap scum, toothpaste, etc., that cause drains to become slow and eventually cause clogs. Bloc-Aid does not contain corrosive acids. It is safe to use in garbage disposals, septic tanks and cesspools without harm to plumbing. The ready-to-use formula requires no mixing...simply pour into the drain.
