How Do I Choose the Best Drain Cleaner?

Just as you expect the toilet to flush effortlessly, it is normal for the water and soap scum to flow straight down the drain after a good bath.

But sometimes life happens. Even with the best hair loss shampoo, it’s still not uncommon to lose a few hairs in the bathtub. These hairs may be one of the many reasons your drain may be clogged.

It is frustrating to experience a backflow due to a clogged drain—even if it only happens on occasion. As more water or waste is added to the stuck pipe or drain, a messy and stagnant puddle may start to form in your bath, toilet bowl, or kitchen sink.

And for all it’s worth, a stuck pipe or drain may just show up at a time when a feisty and pesky mother-in-law decides to spend the weekend at your place. We can already tell what a weekend without an unclogging solution would look like.

What to do? Get a drain cleaner.

Drain cleaners are formulated to unclog your drains whenever there’s an impedance in the free flow of waste, suds, and scums down the drain. While a plunger can definitely help, a decent drain cleaner may be all you need.

With drain cleaners, you only need to apply a generous amount to the stuck drain and then simply wait for the chemical to do its magic. Of course, you may choose to get busy with some other task while the drain is being unclogged. This means you can channel that fraction of your day into doing something else.

But not every drain cleaner on the market can do your drain’s bidding. You should go for the one that will meet your needs perfectly.
If you’ve got a few minutes, we would like to let you in on the things that matter when it comes to deciding which drain cleaner to purchase.
The brand of a drain cleaner and the quantity it offers can affect the price of the cleaner significantly. But that doesn’t necessarily mean it will meet your draining needs. Anyway, this doesn’t mean you should fall for cheap drain cleaners that will only get into your drains to pledge their support to the clogs. Typically, you will find a good drain cleaner within the price range of $20 and $35.
Unclogging your drains with a drain cleaner should give you satisfying results. But things could go south if you select the wrong one. Here are a few things to note when choosing a drain cleaner:
  • Type
  • Drain to Unclog
  • Cause of Clog
  • Formula
  • Quantity
  • Safety
Construction and Design
You may want to consider the amount a drain cleaner offers because you will want to know how many times you can use the chemical before you will have to replace it.

Drain cleaners could be in powder, gel, or liquid form. And irrespective of the form in which drain cleaners come, they are often made of strong chemicals which generate heat during the unclogging process. The three types of cleaners you’ll find on the market are:
  • Caustic drain cleaners: These types of cleaners are specially formulated to turn grease into a substance that dissolves easily. And because they are denser than water, they have the ability to get through standing water and unclog drains
  • Oxidizing drain cleaners: They may contain peroxides, nitrates, and household bleach that dissolve clogs through chemical reactions. They also have the ability to get through standing water and emit gas and heat that helps to unclog the drain
  • Acid drain cleaners: They are not as common as the other two and are often sold to plumbers only. They are formulated to chemically react with and produce heat sufficient enough to melt and dissolve congealed grease
Once you’ve figured out which type of drain cleaner you need, you can look at some other purchasing decisions.

Do you have an idea of the cause(s)?

It’s ok if you don’t know what caused the blockage, but you’ll be one step ahead in finding a solution if you do know. For instance, if the clogging is in your bathtub where you wash your hair occasionally, then you may consider buying a drain cleaner that can dissolves hairs and unclogs the drain.

With kitchen sinks, the major culprits in drain blocks are food particles that may find their way in while you are doing the dishes. In such a situation, choosing a cleaner that breaks the food into smaller particles is advisable.
Performance and Ease of Use
Why do you need a drain cleaner?

Apart from the obvious reason, which is to unclog a blocked drain, a drain cleaner may also be used for maintenance purposes. For good measure, you may want to apply drain cleaners to your drains to prevent blockages. If that’s your main aim for selecting a drain cleaner, then we advise you to go for a mild one since you are not actively unclogging a blocked drain. But if you want to unclog a blocked drain, then a tough one will be a preferable option. And depending on the extent of the blockage you may go for something even tougher.

By now, you must have figured that most drain cleaners generate heat, which is likely to soften pipes and drains. Although, based on a number of findings, the chances of such damage to the drains occur when strict adherence is not given to application instructions or, in some cases, when the pipes are old or made from metal.

Safety first.

We can’t stress enough the fact that instructions are life. So ensure you read and adhere to the instructions that come with the drain cleaner you eventually select. You should also take heed of the warnings. And whatever you do, do NOT mix drain cleaners, and do NOT use plungers when you are using drain cleaners.

Use a drain cleaner only when you have rubber gloves on and, of course, in a well-ventilated area. For the safety of your pets and kids, keep them busy in another part of the house far away from the drain you are working on.

Finally, with drain cleaners, you may need to wait for at least 15 minutes to get a thorough job done. Afterwards, you will need to flush the drain with hot water.

What is the Best Drain Cleaner?

One thing is common to all drain cleaners: they are designed to unclog drains. But some drain cleaners come with extra features that you may find suitable for your needs. To make a perfect choice, we advise that you take note of the things you are more particular about as we take you through our review of awesome drain cleaners.
