Most plumbers will advise you not to use Drano to unclog your drains. This is because the chemical compounds are hard on your pipes, causing corrosion and other long-term damages. Drano is designed to continually react and generate heat within your drain until the clog dissolves.
But it's also one of the most commonly misused products out there. Any plumber will advise against its use.
Drano has been known to cause toilet bowls to crack, soften and break PVC pipes and break older corroded pipes. Over time, the continued usage of Drano can lead your pipes to corrode, crack and eventually fail.
Some of the best Drano alternatives include using a plunger or pipe snake, soap or salt mixed with boiling water, or baking soda and white vinegar. Also, for maximum effectiveness, you can combine several of these methods together to get rid of the clog.
Baking soda and white vinegar are sustainable substitutions for Drano. Most people have these items in their pantry at any given time. Pour a half cup of baking soda into your drain with a half cup of white vinegar. Let it sit for about thirty minutes, then pour in boiling water.
While the phosphoric acid found in cola can help alleviate some minor clogs, carbonated beverages are certainly not the ideal drain cleaner. Better DIY methods include a baking soda/vinegar mixture, a plunger, or a plumber's snake.
Baking soda, vinegar and boiling water can help clean drains naturally, but you may need something stronger, like Liquid-Plumr, to fully unclog those really tough drain clogs.
Yes, the heat these chemicals produce will break down the remnants of a clog, but likely only push them farther down your system to form a more dense clog in a harder-to-reach section of your plumbing. This leads to repeat clog offenses, repeat pouring, and the eventual ruin of your plumbing system.
The chemicals in Drano may not solve all clogs, and they can lead to a worsening of pipe issues. Drano can build up in a clogged area, and corrode the pipe. With repeated use, these chemicals may eat their way through a pipe, and cause a leak or a collapse of the system.
Because of its corrosive nature, Drano can cause toilet bowls to crack, PVC pipes to melt or break and the glue that holds pipes together can be eaten away. If any of these things happen, you're going to be left with an inoperable plumbing system and costly repairs.
The chemicals in the product are designed to break own the clog, but if left for too long, they can start to break down the pipes themselves. This can lead to cracks and leaks in the pipes, leading to various issues, including water damage and flooding.
Using a snake is also more invasive and time-consuming than using a chemical cleaner is, and can often become a dirty job. When it comes to getting at and removing major clogs or clogs that are deep down in your pipes, however, a plumber's snake is your best bet.
Single Use, Not Frequent Use
Because of the chemicals found in these types of products, you could cause irreparable damage to your pipes. In most cases, a single use of Liquid-Plumr or Drano will not cause any issues with your pipes, though you should avoid using them in your toilet.
For example, if you use flange plunger or toilet auger to unclog the toilet after using Drano, it could accidentally splash on you and burn your skin. And if you try to mix Drano with another chemical cleaner, it could create toxic fumes. Source: Household Product Database.
Baking soda and vinegar may unclog your drain better than Drano ever could. Start by getting rid of the standing water in your drain. If it will go down slowly, just wait until it's gone. If it isn't moving, use a cup or a spoon to get it out of there.
You can use Drano® Clog Removers to unclog a kitchen sink, bathroom sink, shower or clogged bathtub, but DO NOT use them in toilets. For clogged or slow-running drains, apply the product and let it work 15 minutes, then flush with hot water. For tough problems, allow 30 minutes before flushing.
Using a solution of baking soda, vinegar, and hot water
For more stubborn clogs, a combination of baking soda, vinegar, and hot water may do the trick. Because vinegar is an acid and baking soda is a base, mixing the two will cause a chemical reaction that will create pressure and possibly dislodge the clog.
If you suspect a grease clog, a mixture of very hot water and vinegar can also help melt and remove the grease that's blocking the pipes. Allow it to work for a few minutes, then use a plunger to help move the clog along. You may have to repeat this more than once.
It is safe to leave baking soda (and vinegar) to work overnight to unclog a drain. Always flush this mixture down with boiling water—no matter how long you leave it sitting in the drain.
The Santeen Sulfuric Acid Drain Opener proved to be the most potent among all the chemical drain cleaners we tested, effectively dissolving 80% of the hair, 80% of the organic matter, 40% of the grease, and 76% of the paper products.
Baking Soda and White Vinegar
This mixture is a great green alternative to Drano because most people have these items somewhere in their kitchen. To use this method, pour half a cup of baking soda into the clogged drain and follow it with a half cup of white vinegar.
However, if you've got some time, this is a super easy fix. All you need is a 20 oz to 2 liter of cola. Pour the cola in the toilet. Let it sit overnight.
