Best Drain Cleaners - Buyer's Guide

type

There are many types of drain cleaners, including those made of powder, gel, liquid, foam, and so on. The importance of the type you choose will affect the effectiveness of the cleaners themselves and how well you will be able to use them. Generally speaking, though, your choice would depend on the surface you are working on and the level of blockage you are dealing with.

purpose

Drain cleaners can vary depending on what you can use them for and where. Some drain cleaners are multi-purpose in that you can use them to clean any clogged pipe and dirty surface. Then there are drain cleaners that are intended only for blocked toilets or kitchen drains. It’s important to pay attention to this detail so as to avoid causing damage to your pipes.

quality

As with many things, drain cleaners can drastically differ in terms of quality. This is important to note because the quality of a drain cleaner will affect how well it can unclogged drains. The best ones will do so in a matter of minutes while others would take hours or longer. In the case of low-quality drain cleaners, they may not even work or will cause damage to your pipes.

amount

In many cases, clogged drain pipes can be cleaned out after one or two cleaning sessions. As such, you should keep the size or amount of your drain cleaner in mind before buying one. Of course, this will also depend on how potent the chemical concoction is and how bad the blockage has become. Weaker drain cleaners will require you to use more of it in order to get the job done.

safety

Drain cleaners are potentially dangerous by nature. As such, you will need to be careful if you are using them. In some cases, the chemicals can be harsh enough that they will irritate or damage your skin upon contact. On that note, there are also some drain cleaners that won’t pose that big of a risk. Unless you breathe in their fumes directly, using them is relatively safe.

Best Drain Cleaners - FAQs 

How do drain cleaners work?

Drain cleaners are potent chemical mixtures that are specifically intended to react to a variety of waste matter. In most cases, these reactions will involve softening and dissolving hardened particles that are causing clogs and blockages. Heat can also be generated, as a result, which will help in loosening the combinations of hair, grease, waste, and soap. As a result, they would detach and flow away more easily.

Do all drain cleaners work the same?

Generally speaking, yes, they do. Though drain cleaners can actually come in many forms such as powder, gel, liquid, crystals, and foam, they will function in much the same way. As such, it all comes down to how convenient you want them to be and what other purposes you may have for them. Some drain cleaners can actually be used for cleaning other surfaces.

Will a toilet drain cleaner work on clogged kitchen pipes?

Drain cleaners meant for clearing out pipes will work on pretty much any kind, regardless of where it is located or what it is used for. This means that the same drain cleaner you use for your toilet could also work on the pipes connected to your kitchen sink. However, it is generally advised to avoid doing this unless it is explicitly mentioned in the label that it works on both. Some drain cleaners can have mixtures that are too potent for relatively thinner and smaller pipes.

Are drain cleaners safe to use?

With drain cleaners being composed of potent chemicals, it is never a good idea to touch them directly with your skin. It would also be advised to avoid inhaling their fumes directly and they must never enter your body through your eyes, nose, mouth, or open wounds. As such, when using drain cleaners, you might want to wear a mask, gloves, and eye protectors.
