Buying Guide

If you are looking for the best drain cleaner, you should always consider two key variables. The “type” or chemistry of the product. And the safety precautions you will need to take.

Types of Drain Cleaners

You will find three types of drain cleaners commonly sold; acids, alkalis, and enzymes. They each have their pros and cons which are discussed below.


This type of drain cleaners is powerful and they often sulfuric or hydrochloric acid. They can dissolve clogs in both sinks and toilets. Hair, food, grease, soap scum, and paper products are no match. Plus they work fast, usually within 15 minutes or less.

So, why aren’t there more acid-based products on the store shelves? Simple, they are strong chemicals that dissolve all clog types. But that means they can also severely burn your skin and damage your eyes on contact.

This family of drain cleaners will not affect copper and newer plastic pipes. But acid corrodes most other types of plumbing. So, be sure to understand if your plumbing is acid-resistant in advance.

Plus, these products often bubble and create pungent fumes. Ventilation is often required.

If you want a strong, fast universal product, get an acid-based drain cleaner. But you must diligently follow the safety instructions.


Alkali drain cleaners use caustic chemicals to convert obstructions into a soap-like material. You then simply wash the debris away with water. They usually work in about 30 minutes.

This type of product breaks down food, grease, soap, and hair. But they are not effective with paper products. So, they are not recommended for use in toilets.

Pipes older than 20 years may be susceptible to damage. Some old plastic pipes can soften. Plus, aluminum, galvanized, and brass pipes can tarnish or corrode. Check that you have modern pipes that are corrosion resistant before using.

In general, this family of drain cleaners is safer to handle compared to acids. Plus, they are usually odorless. But remember, alkalis can burn skin, too, and irritate the eyes and nostrils. So, use personal protective equipment.


Using enzymatic activity to “feed” on the clogs, this family of products is effective on hair and paper. They do take longer to work, sometimes up to 24 hours. Also, many manufacturers recommend using these products once a month to prevent build-up.

You can remove grease, but not as well as with acids or alkalis. In places where there is heavy grease buildup (e.g. kitchen sinks), you may want to use another type of drain cleaner.

Enzyme-based drain cleaners have and advantage over other types of products. They are safe to handle since they are far less toxic than acids and alkalis. There is also no need to worry about your pipes, fixtures, or septic system.

How to use

Most drain cleaners are simple to use. You pour the product down the drain or toilet, wait a certain amount of time, and rinse. Some details do vary such as certain cleaners work best with very hot water to rinse. So, read and follow the instructions.

Safe handling of the products requires care. Many drain cleaners can severely burn your skin and damage your eyes or nostrils. So, you should use gloves, goggles, and a respirator when using these products.

Most manufacturers print detailed safety information on the label. They do this to help protect you. Follow their advice to the smallest detail to keep yourself safe.
