Most people prefer using liquid drain cleaners because they only require you to pour it down the drain and wait for them to work.

They also do a quick job of clearing any obstructions from your drains. What the liquid does is to create a chemical reaction that dissolves the substances causing the clog. Once the elements are eliminated, you simply need to pour water down the sink and the problem is solved.

Types of Liquid Drain Cleaners

There are 3 main types of liquid cleaners which include:

Caustic, oxidizing and acidic.

Caustic drain cleaners contain caustic potash and lye substances. These are the bases that give electrons to the clogging substances. Their hydroxide ions normally create the reaction that clears the clogs. Their basic or alkaline chemicals emit heat, which turns the grease into a soap-like substance that is easily dissolved.

This type of drain cleaner is normally heavier than water, and this enables it to reach the clog using the standing water.

Oxidizing drain cleaners have substances such as peroxides, nitrates, and household bleach, which causes the clogging substance to lose electrons and as a result, it will become oxidized. it is much heavier than water, and so it moves through standing water and it releases gas and heat that eventually clears the blockage.

Acidic drain cleaners are very common, and they can be found in almost any store. They are mostly sold to plumbers because they contain high concentrations of sulfuric and hydrochloric acid. These acids are able to increase the hydronium ions that attract electrons from the clog.

The hydronium ions will then chemically react to the material in the clog and release heat which melts grease.

Things to Look Out For When Buying Liquid Drain Cleaners

The following points will help you in choosing the best liquid drain cleaner for your home;

The type of blockage: This refers to the reason behind the clogging. If your drains have a big clog, which means that the blockage is too much, then, you will need a very strong drain cleaner, preferably a very heavy liquid product to clear out the clog.

You can test the size of clog by pouring hot water down the drain. If it doesn’t help in removing it, then the issue is much more serious than you would have thought.

Your maintenance technique: How often do you care for your drains? Do you clean them often? Do you ensure not to pour elements that may clog your sink down the drain? These are questions you will need to answer in order to identify the kind of problem you have at hand.

If you do regular maintenance, then you are probably safe and the problem may not be as big as you thought.

Type of pipes: Bare in mind the type of pipes you have in your home because some pipes are easily destroyed by chemicals. When buying the drain cleaner, read carefully the chemical composition on the bottle, to ensure that it will not destroy your pipes after use.

Cost: This is important because at the end of the day, what you pay for is what you get. What I mean is that you do not expect to find a good quality drain cleaner being sold cheaply. While this doesn't necessarily mean you go buy the most expensive, it simply means that price should be one of your deciding factors
