Buying Guide: Drain Clog Removers

A clogged drain can have detrimental effects, and you should always try and unclog a drain as your priority. To do this, though, you will need a suitable drain clog remover. As such, we have compiled a buying guide that will help you choose the most suitable drain clog remover according to your needs. Let’s take a look!

The Different Physical States of Drain Clogs

A drain clog remover formula comes in four states: liquid, gel, powder, and granular. You should choose the type of formula depending on the kind of clog you have.

Powdered drain clog removers are best for slow-running drains; you should not use them in quick-running drains as they need to sit on the clog for a while to act. On the other hand, liquid drain clog removers are the most commonly used and can work on any type of drain fast. Similarly, the gel and granular removers work for every type of drain, too. 

Different Types of Drain Clog Formulas

There are different types of drain cleaners available in the market, and each type differs from the other in effect it has on a clogged drain. Drain clog removers can be divided into two types based on the formula:

Enzymatic 

An enzymatic drain clog remover contains enzymes as the formula’s main ingredient. The enzymes gradually break through the clog and are harmless to you and your pipes, so if safety is your main concern, you should go for this cleaner. 

That being said, the enzymatic formula takes a long time to show results because the enzymes are slow in dissolving clogs. Plus, the enzymes can only cut through organic matter like clogged hairs or food — any other blockage will be left as is. 

Chemical

On the other hand, chemical-based drain clog removers work extremely fast. Unfortunately, most chemical-based drain clog removers can damage the pipes of your drainage system. Metal pipes can corrode from excessive use of the drain clog remover, whereas PVC pipes can melt from the heat released by the chemicals while in action. Chemical cleaners can further be put into three different categories:

  • Oxidizing drain clog remover

Made with bleach, nitrates, and peroxides, an oxidizing drain clog remover easily dissolves organic clogs like hair and food by oxidizing them. Hence, they are the perfect choice for use in toilets, bathroom sinks, and shower drains. 

  • Caustic drain clog remover

This type of chemical-based drain clog remover contains caustic potash and lye. Not just that, it also contains alkaline substances that are perfect for melting grease clogs in your kitchen sinks. 

  • Acidic drain clog remover

These drain clog removers contain a high concentration of acids like hydrochloric and sulphuric acid. As such, they are mostly used by plumbers and should be avoided as they can easily burn you.

People Also Asked

Q: Should I use boiling water for unclogging drains?

A: If used as a standalone solution, boiling water might not unclog drains properly. Instead, you can use a combination of boiling water and a drain clog remover for effective drain unclogging. 

Q: How long can I store a drain clog remover?

A: Before opening the product, you can store a drain clog remover for at most 12 months. But, if you have opened the product, then you can only store it for a few months before it is rendered ineffective.

Q: Can a drain clog remover be used to unclog toilets?

A: It is not recommended to use a drain clog remover for unclogging toilets or dishwashing systems. A drain clog remover’s use should be limited to septic systems and drainage systems.

Q: What do drain clog removers do?

A: Drain clog removers break down and dissolve particles blocking your pipes/drains. Hair, dust, skin, food, and more can create blockage in your pipes causing your sink to drain slowly. The chemical formula of the drain cleaner breaks this down to clear the path. 

Q: Should I use a drain snake with my drain cleaner?

A: If your issue progresses and the drain cleaner is not effective in dissolving the blockage, you may want to employ a drain snake. Be sure to wait a day or so between using the drain snake so you don't splatter any of the solution.
