Enzymatic drain cleaners contain bacteria cultures and concentrated enzymes that react with organic residue that builds up on sewer pipes, dissolving the residue to help prevent slow-running drains. Most enzymatic drain cleaners are intended for general maintenance to maintain proper flow and are not intended to clear fully clogged drain pipes.
Advantages of enzymatic drain cleaners include relative safety for use in a wide range of plumbing fixtures, low environmental impact, low cost and ease of use.
Disadvantages of most enzymatic drain cleaners include longer cleaning times compared to most other drain cleaners. Because enzymatic cleaners rely on liquid flowing through the pipe to disperse, they are also generally not intended to open completely clogged drains.
Safety considerations for enzymatic drain cleaners include a requirement to avoid contact with eyes and prolonged contact with skin.

Famous quotes containing the words drain and/or cleaners:
“Why is it so difficult to see the lesbian—even when she is there, quite plainly, in front of us? In part because she has been “ghosted”Mor made to seem invisible—by culture itself.... Once the lesbian has been defined as ghostly—the better to drain her of any sensual or moral authority—she can then be exorcised.”
—Terry Castle, U.S. lesbian author. The Apparitional Lesbian, ch. 1 (1993)
“I could have taken you to the cleaners and made love to a woman at the same time.”
—Blake Edwards (b. 1922)
