Three Main Types of Drain Cleaners,
* Caustic Drain Cleaners: It contains a substance such as lye and caustic potash. These drain cleaners are typically heavier than water, which enables them to reach the clog through standing water.
* Oxidizing Drain Cleaners: It contains a substance such as household bleach, peroxides and nitrates. This product is heavier than water, so it can move through standing water, and it can releases heat and gas to help clear the blockage.
* Acid Drain Cleaners: It isn’t commonly found in stores, and some are sold only to plumbers. Acid drain cleaners typically contain high concentrations of sulfuric acid or hydrochloric acid, substances that increase hydronium ions in a solution and attract electrons from the clog.
