What is a Liquid Drain Cleaner?

Liquid Drain CleanerWhen your drain is clogged, you’ve got a problem on your hands that you want to solve fast. There’s nothing more annoying than a sink filled with stuck water and we can feel overwhelmed when it comes to finding the right product to get that 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 doing research and determining which one 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 perfect liquid 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 liquid drain cleaner that will get the job done for you for much less money. Once you get that drain unclogged it’s also a good idea to learn how to keep it unclogged in the future. You’ll definitely want to prevent 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 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 the best. What really makes a cleaner stand apart is its performance and this performance will likely be praised online by existing 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 cleaners simply cannot fix. 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 without having to employ an actual 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 are not urgent to clear. Lastly, take into account the use of the pipes you’re wanting to unclog. Most blockages will occur in the drain under your kitchen sink and it is usually a build up of grease 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. Nowdays you can even find fume-free products that can accomplish this without the strong, pungent smell.

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 tank. In this case you will want to opt for a manual pipe cleaning tool.

The Cost to Unclog Your Drain

The great thing about liquid drain cleaners is that they’re all quite affordable and they certainly beat having to call a plumber. In fact, the top-rated liquid 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 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, 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 cleaners that can get the job done even though prevention should be your first line of defense.

drain cleaner for toiletWhen it comes to your kitchen sink, you need to keep anything from going down the drain unless you have a garbage disposal. That means buying a mesh cover at your local hardware store to catch food items so you can throw them in the trash. Should you have a food disposal, then you won’t need to worry about this, but just know that grease and waste can still build up over time and clog the drain.
