Liquid Plumr Vs. Drano – Which One Works Better On What?

If you’re a homeowner, you must be familiar with the struggles of cleaning and maintaining a drain. These drains are undoubtedly the dirtiest and stringiest things in your house. Whether it is your kitchen sink or toilet, a clogged drain can create an annoying situation.

If they are not cleaned for a longer time, they become clogged, spreading foul odor and bacteria. Almost every drain requires rigorous cleaning every six to eight months. But to do so, you must know which cleaner to use, especially if you’re stuck between the debacle of Liquid Plumr vs. Drano.

Chemical cleaners like Liquid Plumr can dissolve chemical obstructions, such as soap, as well as the majority of organic materials obstructing your drain. On the other hand, Drano is a gel-based drain product that quickly clears clogged drains and improves water flow. It is also sold separately as a foam-based cleanser.

Liquid Plumr

Liquid Plumr(Check on Amazon) is produced by an American company named Clorox. It’s even rated as one of the top ten most popular Health and Household goods.

The product instantly clears fully blocked drains, thanks to its robust triple action strength. While emptying the gutters, the Pipe Guard capability coats your pipes to protect them from damage.

How Does Liquid Plumr Work?

Liquid Plumr’s formulation is triple-action. Sodium hypochlorite (often known as bleach) and sodium hydroxide (sometimes known as lye) are the two main active constituents in Liquid Plumr. 

Bleach reacts with lye and water when the drain cleaner is mixed with water. So the cleaner degrades and produces heat. The mixture passes through pipes and dislodges obstructions. Liquid Plumr takes about 15 minutes to prepare.


Drano(Check Price on Amazon) is a drain cleaner made by S.C. Johnson & Sons in the United States. Drano contains sodium silicate, liquid glass, and specific compounds that have been known to react with sodium silicate.

As a result, you may see a chemical reaction if you have used other pipe-cleaning products before using Drano. Because of the liquid-glass reaction, PVC pipes cannot handle Drano. If you have PVC pipe, avoid using Drano because it will do significant damage.

Some people dislike this one because of the mess it causes. However, the product is safe to use with most pipe materials and septic tanks.

How Does Drano work?

Sodium hydroxide is one of Drano’s vital active ingredients. It decomposes organic waste. Drano, unlike other solutions, contains aluminum shards, which help create a significant chemical reaction and heat. The breakdown process is accelerated by heat.

Lye combines with softened grease to form soap, which is then dissolved in hot water. It eventually reacts with metal, forming hydrogen bubbles as a result. These bubbles aid in the loosening of blockage particles. 

Drano starts a series of chemical reactions in a sequence, making it extremely strong.

Although the two items are identical, you must choose which one to use for your drain blockage problem.
