Crystal Drāno


According to the National Institutes of Health's Household Products Database, the crystal form is composed of sodium hydroxide, sodium nitrate, sodium chloride, and aluminum.
The ''power crystals'' are simply colored salt, and are the least powerful ingredient. The crystallized lye reacts with fats to form soap. The machined shards of aluminum react with the lye to generate near-boiling temperatures. The sharp shards in the hot churning lye physically cut hair and dislodge deposits. Several chemical reactions take place here:
1. When Drāno is added to water, the sodium hydroxide, sodium nitrate, and sodium chloride dissolve. The heat of solution liberated when sodium hydroxide is dissolved warms the mixture.
2. In solution, sodium hydroxide reacts with aluminum to liberate nascent hydrogen, which is a powerful reducing agent. This reaction is exothermic and the heat can cause the mixture to boil. The formula is 6NaOH + 2Al → 3H2 + 2Na3AlO3.
3. The nascent hydrogen reduces nitrate ion to ammonia, removing the fire and explosion hazard posed by free hydrogen gas. The reaction is: 2NO3 + 9H2 → 2NH3 + 6H2O. The water and sodium ions then regenerate sodium hydroxide and nascent hydrogen.
Crystal Drāno was invented in 1923 by Harry Drackett. Even as Drackett grew to offering over a hundred household cleaning products in the late 20th century, Windex (introduced a decade later) and Drāno provided the lion's share of revenue and profits. Bristol-Myers bought the Drackett Company in 1965 and sold it to S.C. Johnson in 1992.
For years, Drackett advertised ''Once every week, Drāno in every drain''. As many clogs form where a bacterial matrix makes the pipe walls less slippery, the disinfectant action of the hot lye may prevent clog formation. Various mixes of relatively non-toxic solvents are now sold commercially for the purpose. To a certain extent (see Sterilization), even dumping a gallon of scalding water down the drain, however, would have a similarly salutary result with substantially less damage to the environment and the budget.

Other Drāno products


Drāno Aerosol Plunger was developed in the late 1960s, intended as a safer product that would be kinder environmentally. It was basically just a can of CFC propellant, the best-known brand of which was Freon. After Earth Day in 1970, there came increasing pressure to eliminate CFC propellants. Drackett used cheaper propellants, a blend of propane and butane, in all its other products. However, the propellant mix created a fire hazard.
The product was problematic. The forceful propellant required most consumers use both hands to control the can, plus another hand or two to hold a rag over the drain vent to contain the pressure. The pressure sometimes knocked apart poor plumbing without blasting free the clog. Consumers who ignored instructions and attempted to use chemical drain openers first could be chemically burned from blow-back. The aerosol product was only useful against complete clogs, not against slow drains.
Liquid Drāno was introduced in response to Clorox's purchase of Liquid-Plumr in 1969. Originally, it was simply a liquid lye (sodium hydroxide) but that product proved ineffective and unpopular with consumers. In the late 1970s, the product was reformulated as a combination of liquid lye and sodium hypochlorite. Sodium hypochlorite is sold in 5% concentration as laundry bleach and in 10% concentration as a swimming pool disinfectant.
Foam and gel products have been introduced in recent years, marketed more for slow drains than for opening clogged drains.

Drāno bombs


In 2003, Sherman Austin was sentenced to a year in federal prison for publishing instructions for making Molotov cocktails and "Drano bombs" on his website. A 1997 law makes it illegal to publish such instructions with the intent that the reader commit a violent federal crime. Dr. David S. Touretzky has since mirrored Austin's site.[1]
While Molotov cocktails are simple to make and use for an incendiary device, Drano bombs are not. Most instructions online put the bomb maker at serious risk.
The phrase "DrĀno Bomb" can also refer to a less serious device often used by pranksters to make a large pop. This leaves a chemical cloud in a small radius and can be very unpleasant.

Murders


In 1974, Pierre Dale Selby and William Andrews used Drāno in the Hi-Fi Murders having been inspired by a scene in the motion picture ''Magnum Force'', in which a prostitute is forced to drink Drano. The murderers were captured and sentenced to death.
Drāno was used in the 1996 murder of "Angel" Melendez by Club Kids Michael Alig and Robert "Freeze" Riggs over a drug debt. This was later chronicled in James St. James's memoir Disco Bloodbath, and the documentary and film Party Monster.
