Drain cleaners work best on slow moving drains. They are less effective in clogs with standing water.
Drain cleaners are not recommended in houses with a septic system, as they can kill the bacteria inside the tank that help break down waste.
Some products use a two part formula to generate a kind of “foaming” action. These are good for removing buildup, but should not be used in a completely blocked drain. Enzyme formulas exist, which attack the protein and fat bonds of clogs. These are safer and can be used on toilets and tubs, but are slower and less effective. Heavy-duty formulas usually contain 100% pure lye or sulfuric acid. These are effective but can be highly dangerous to the untrained.
Open the bottle while grasping the handle. Do not splash or squeeze. Pour the specified amount into the drain. Allow up to 30 minutes for the clog to clear. Flush with plenty of hot water.
Remove any standing water. Add 1-3 tablespoons of product into drain. Add one cup of cold water. Allow up to 30 minutes for clog to clear. Flush with cold water.
