Drano is a clog-removing chemical solution produced by the household product company S. C. Johnson. It is designed for removing clogs in drains of all sorts, including bathtub, shower and sink drains. In addition, you can use Drano in your garbage disposal. However, do not use Drano in your toilet.

What Does Drano Dissolve?

Drano dissolves many materials that are the culprits of clogs in your drain, including soap scum remnants, hair and general unidentified gunk. The solution is formulated from several chemicals that work to dislodge the clog and free your pipes so that water can flow freely through them.

Designed for Drains

Drano is designed for drains and not for toilets for several reasons. Drano can damage your toilet by causing the wax ring sealing your toilet to deteriorate. After repeated use, you may have to replace the ring and may even need to replace the floor below the toilet because of chemical overflow onto your subfloor.

Plunging Warnings

You do not want to use Drano in your toilet for the above reasons as well as the dangers you may encounter while plunging the toilet. Because Drano is formed from chemicals, plunging a toilet with Drano in it can cause the liquid to spurt and get on your skin, in your eyes or in your mouth. If you have mistakenly poured Drano into the toilet, do not plunge the toilet.

Additional Drano Warnings

S. C. Johnson's official website lists the following Drano products as safe for drains and garbage disposals: Drano Liquid Clog Remover, Drano Max Gel Clog Remover, Drano Pipe & Septic Care and Drano Dual Force Foam. Do not use Drano Kitchen Crystals Clog Remover on your garbage disposal. The only Drano product listed as safe for use in your toilet is Drano Pipe and Septic Care, although the website states that this product will not open a completely clogged toilet.
