Is Drain Cleaner Acidic Alkaline or Neutral?

Sewer blockages may be very annoying, especially if they happen regularly. Blocked-up pipes may be resolved by yourself with solutions such as drain cleaner. So what is drain cleaner? Is drain cleaner acidic, alkaline or neutral?

 Is it safe to use? Let’s find out.

What is Drain Cleaner?

A chemical substance known as a drain cleaner is used to clear or unclog drainage pipes, wastewater drains, bathroom and kitchen pipelines, and other pipework.

Over time, these sewage fittings fill up with organic debris like oil, hair, and food scraps. These organic materials have the potential to block water flow, which can lead to a poor drainage system and other plumbing issues when they collect in one area.

The average person will find it too challenging to determine which section of the pipeline is jammed, so they employ a chemical drain cleaner. Retail stores have chemical drain cleaners, which are supplied in either liquid or solid form.

Is Drain Cleaner Acidic, Alkaline or Neutral?

Depending on the reason for the obstruction, a drain cleaner could be acidic or basic. The acidic kind works in dissolving toilet paper in pipelines and dissolving grease and hairs. However, the alkaline drain cleaner unclogs obstructions by unleashing particles that interact with the pollutants to dissolve the blockage. Depending on its composition, every drain cleaner’s ph scale will reveal whether it is an alkaline solution or an acid solution.

What is pH ?

A solution’s pH level determines how acidic or alkaline the liquid is. The pH scale has values from 0 to 14. Anything below 7 denotes acidic characteristics, whereas level 0 is the most acidic. Anything greater than level 7 is more basic. On a pH scale, point seven is neutral.

Is Drain Cleaner Acidic, Alkaline or Neutral?

Drain cleaners can be alkaline or acidic. The task at hand influences the strength. The commercial variety might be either very acidic or very basic. It could be neutral if you want to use it to dissolve any acidic or basic compounds.

However, Some of them might not be able to assist you clear the tough blockage if you didn’t get the product for your need.

Acidic Drain Cleaners

The pH of acid drain cleaners is low. This is because H2SO4 or HCl is their primary active component. These acids have the power to clear up tenacious drain blockages. Inside the pipelines, they may disintegrate toilet paper, oils, and fur.

Sulfuric acid-containing acid drain cleaners need to be treated with care. If you breathe in the toxins from these kinds of drain cleaning, your lungs may become irritated. Touching the liquid might potentially cause skin irritation.

Your pipework might be harmed by this intense acidity. Additionally, they could erode adhesives and surface coatings, which might cause leakage.

Alkaline Drain Cleaners

Several alkaline drain cleaners might contain KOH, while NaOH makes up the majority of them. Both liquid and solid base drain cleaners are available. On a pH scale of 1 to 14, alkaline drain cleaners can get a score as high as 14. These drain cleaners are significantly more hazardous than chlorine since they are far more basic.

Most basic drain cleaners function by re-oxidizing hydrogen gas. The additional heat output then aids in dissolving the oils, animal fats, etc., which contributes to the blockage. Since hair includes proteins and these cleansers also produce hydroxide ions, they can disintegrate hair.

Base drain cleaners are effective. However, a few are only truly beneficial when used directly to a blockage. They will consume the clog’s lipids, protein, or other things if used on it. It won’t be able to use this approach to unclog a clogged toilet. This may worsen the situation since it may loosen any objects adhered to the pipes’ sides, which will eventually cause them to trickle down and exacerbate the blockage.

If the basic cleaner is a watery version of harsh alkaline, the fluid will descend to the blockage. It’ll be able to go to the obstruction where oxidizing will happen. By generating air and creating heat, it will transform grease into a substance that resembles soap. Eventually, this soapy material will be simple to liquefy.

Additionally, many drain cleaners can result in irritation and release harmful smells when mixed with other home goods. PVC pipes may become damaged by the heat created during the unblocking procedure. Homes that utilize fluid drain cleaners typically involve leaks.


What Occurs If a Lot of Drain Cleaner is Used?

When you utilize far too much cleaning solution, your pipelines may corrode. If you combine different solutions, you may even trigger chemical changes that generate heat or poisonous fumes that are hazardous to both you and the surroundings.

Can Drain Cleaner Catch on Fire?

Drain cleaners shouldn’t be kept next to products that might catch fire. Although the majority of these cleansers aren’t individually explosive, they can significantly worsen flames that already occur. We recommend keeping them far from those other flammable substances.

How Should I Use Drain Cleaner?

Pour a half-litre drain cleaner over the drain to be used on blocked or slow-running drains. Give it atleast Fifteen minutes to complete. And Use hot water to flush.

How Long Must I Leave It Before Draining the Drain? 

After pouring the solution down the drain, give it a minimum of fifteen minutes until emptying with fluid. You can safely leave the product overnight if you have a challenging blockage.


Even though there are alkaline, acidic and neutral drain cleaners, the most popular drain cleaners seem acidic due to their higher efficiency than other drain cleaners. However, they could be dangerous, so you should exercise caution and determine their pH before using them.

However, figuring out the drain’s pH value before purchasing could be difficult. The majority of retailers offer cleansers without mentioning the pH level. The best action is to purchase the existing cleaning solution and pour it down the drain. Based on the pH level, the h+ ions ion will interact with whatever is obstructing your drain and produce sufficient heat to dissolve the grime, grease, or anything else in the way.
