Editing Drano (section)

===Liquid Drano===
Liquid Drano was introduced in response to [[Clorox]]'s purchase of [[Liquid-Plumr]] in 1969. Originally, it was simply a liquid lye (sodium hydroxide). In the late 1970s, the product was reformulated as a combination of liquid lye and [[sodium hypochlorite]]. Sodium hypochlorite is used in low (5%) concentration as laundry bleach and in higher concentrations as a swimming pool disinfectant.<ref>https://www.in.gov/isdh/files/Chemical_adjustment_pool.pdf {{Webarchive|url=https://web.archive.org/web/20170210111116/http://in.gov/isdh/files/Chemical_adjustment_pool.pdf |date=2017-02-10 }} {{Bare URL PDF|date=March 2022}}</ref>

Liquid Drano is marketed in several forms, including Drano Liquid Clog Remover, Drano Max Build-Up Remover, and Drano Dual-Force Foamer Clog Remover.  All are variations on the basic Liquid Drano formula.<ref>{{cite web|url=http://www.drano.com/en-US/Pages/Home.aspx|title=Drano - For Clogged Drains and Septic Tank Treatment - SC Johnson|access-date=16 October 2016|archive-date=15 October 2016|archive-url=https://web.archive.org/web/20161015135633/http://www.drano.com/en-US/Pages/Home.aspx|url-status=dead}}</ref>
