As of 2015, Rooto drain cleaner is available from Amazon.com, TrueValue.com and Sears.com. All three retailers sell individual packages of Rooto, but Amazon.com sells a 12-pack.
Rooto is a drain cleaner that contains 100 percent lye, a highly caustic substance, which means it cannot be shipped to Alaska, Hawaii or Puerto Rico, according to TrueValue.com. Each container of Rooto contains 1 pound of lye, and it is safe for all drains, including sinks and bath tubs, and all septic systems. These crystals come in a customer-friendly package, and to use Rooto, the customer must use only one tablespoon directly into the drain. People also use Rooto for other purposes, such as soap making or cleaning tile.
Reviews for Rooto are high, and on Amazon.com, the product has 4.7 out of 5 stars for the single 1 pound bottle and 5 out of 5 stars for the 12-pack bulk package. Since Rooto is 100 percent lye, an extremely caustic substance, customers should only store the crystals in plastic and use rubber gloves, goggles and face masks when handling it, and they should not use the same tools for handling lye as they do for other purposes. Similarly, they must store it where small children and pets cannot reach it.
