Drano Ultra Max Gel, 80 oz

Drano Max Ultra Gel 80 oz. 2 pk is recommended by many customers for maintaining their drains. One customer living in an old house with prehistoric plumbing suggested that it can save money from calling a plumber if used frequently. Another customer was pleased with the delivery and the size as it enables multiple uses. A plumber recommended one cap full once a month to prevent buildup, and it worked well with no more clogs. A customer who couldn't get the sink unclogged tried this product with just one bottle, and it worked. Another customer pours it in the drain, lets it sit for thirty minutes, and rinses it with near-boiling water to keep the drains flowing properly. The only complaint is the lack of a clear strip on the bottle to see how much product remaining.
