What is a Liquid Drain Cleaner?

Liquid Drain CleanerWhen your drain is clogged, you’ve got a problem on your hands that you will want to solve fast. There’s nothing more annoying than a sink filled with stuck water and the overwhelmed feeling you might have when it comes to finding the right product to get the clog out. There are tons of liquid cleaners on the market but most of them are not nearly as effective as they claim to be.

Finding that right liquid cleaner for your situation comes down to good research in order to determine which is the most effective. With so many to choose from, we hope it’s helpful that we did the research for you to determine the top-rated liquid cleaners on the market. These are definitely the best of the best and they’re going to help you to get that clog out in no time.

In this buyer’s guide, we’re going to take it a step further and discuss some facts you need to know before purchasing the best drain cleaner. If you’re a home owner, you will inevitably have an issue, at some point in time, with clogged drains. It’s an unsightly issue that needs to be tended to as quickly as possible.

Before you call a plumber and spend a huge amount of money on having it fixed, you want to consider purchasing a high-quality drain cleaner that will get the job done for you for much less money than a plumber. Once you get that drain unclogged it’s also a good idea to learn how to always keep it unclogged. You’ll definitely want to prevent yourself from ever having to go through the process again.

What Makes a Drain Cleaner Stand Apart?

It can be tedious work to shop for a drain cleaner, especially when you keep trying new drain cleaners that don’t work. You can find them in stores and online but many of them don’t perform as they claim. Bold claims made on the front of a package are no indication of how a product is really going to perform.

You need to stick with the tried and tested brands that consistently stand out from the competition but it can take some time to determine which they are. What really makes a cleaner stand apart is its performance and this performance will likely be praised online by past customers. Going online to read reviews will quickly tell you which product is worth buying and which is a waste of time.

Pre-Purchase Considerations

  • Type of Blockage: You need to first determine the level of blockage that you’re experiencing. You can experiment by pouring boiling water into the drain to see if it gets it to move at all. If this doesn’t work then it may be a difficult clog and time for a professional to come and fix it. There are some clogs that liquid drain cleaners simply cannot fix. A lot of clogs are more than soap scum and require a heavy duty drain opener that dissolve hair. However, in this situation you can still keep the plumber at bay if you’re willing to use a drill or hand powered snake in combination with a chemical cleaner. This two-fold method usually does the trick for tough clogs. If you have experience with home repair and tools, then you can purchase an industrial tool similar to the ones that plumbers use and you won’t have to employ a plumber.

  • Type of Cleaners: Also consider that enzymatic drain cleaners are another type of product that you can use. These usually come in a dry-powder form which gradually dissolves any built-up residue. This is great for slow running drains or for those that do not urgently need cleared. Lastly, take into account the way you use the pipes you’re wanting to unclog. Most blockages will occur in your kitchen sink drain and are usually a build up of grease, soap scum and food waste. You’ll also get frequent blockages in the shower due to dirt and hair. If you have one of these types of clogs, then a chemical solution is going to be the most practical solution. A chemical solution, like the top rated ones mentioned above, will dissolve this waste in no time. Nowadays, you can even find fume-free products that can accomplish this without the strong, pungent smell of chemicals.

Do take note that if your home has a septic tank then chemicals are the wrong choice as they will interrupt the performance of your septic tank. In this case you will want to opt for a manual pipe cleaning tool or natural enzymes.

The Cost to Unclog Your Drain

The great thing about the best drain cleaners other than cleaning soap scum is that they’re all quite affordable and they certainly beat having to call a plumber. In fact, the best drain cleaners cost almost nothing compared to hiring a professional or buying an expensive drain clearing tool.

That’s why it’s such a smart choice to have one of the above drain cleaners around your home at all times. Some of the more advanced products are going to cost slightly more than those you can find at the drug store but the price difference is nominal.

Keeping Your Drains Clear

It’s smart to learn how to keep your drains clear in the first place so that you only need to use your drain clearing liquid infrequently. One of the biggest culprits is hair, soap scum and grease, so be sure to install a mesh cover over the drain in the tub and shower so that hair accumulation won’t clog the drain over time. Also, be sure that you know what can and can’t go down your toilet and sinks. For instance, you only want toilet paper to go into the toilet and should absolutely avoid placing paper towels, Kleenex, feminine hygiene products, or Q-tips in your drains.

These items will definitely clog the toilet over time and no liquid cleaner is going to be able to stand up to them. Also, be sure you’re keeping hair from going down your bathroom sinks. However, should the hair accumulate and create a clog, at least you know that there are liquid hair clog drain cleaners that can get the job done even though prevention should be your first line of defense.
