Instructions to use Drano

Drano manufacturer claims we can use these products safely with plastic or metal pipes if we follow the label directions.

Let’s see below how to use Drano liquid to unclog your drain and other appliances.

Toilet

For starters, you should know that Drano Max Gel Clog Remover isn’t appropriate for toilets. 

You can unclog your toilet with another product, called Drano Max Build-Up Remover, recommended for slow running toilets.

Pour four ounces of the product down the toilet for over three consecutive days. 

Apply Drano overnight or before you go to work. 

Make sure not to flush with hot water your toilet for 6-8 hours after each treatment.

Wait 6 to 8 hours before running warm water down treated drains or flushing treated toilets.

Repeat the entire process using Drano every four weeks. 

Use Drano

If you deal with clogged or slow-running drains, slowly pour half of the bottle (the size of 32 oz.) over a drain. 

For extremely slow-running drains or complete clogs, pour in the entire content of the bottle (32 oz.)

Flushing

What are the instructions for flushing the product with water after placing the liquid in our plumbing?

After you applied the product, wait and let it work for 15 minutes. For tough problems allow 30 minutes for the entire process.

You should already have unclogged your kitchen sink, bathroom sink, shower, or clogged bathtub.

Now flush it with hot water. 

Important: It should be hot water but not boiling. 

Wait a few minutes (15 minutes are too many, but let’s say 5) after you finish to flush with hot water. 

Your job here is done when you see that the sink is not clogged anymore and the water doesn’t run slowly like it used to!

Can Drano be dangerous?

Using Drano products is safe if done wisely. 

Yet, this liquid comes with a list of dangers for both our plumbing and well-being. 

Here’s are the threats we need to be aware of:

  1. Could damage existing plumbing as the combination of dissolving proteins, hot temperature, and bubbles could be problematic for pipes to withstand. It can make metal pipes corrode or crack, or soften and break PVC plumbing;
  1. It can harm your skin, eyes, and lungs because its purpose is to dissolve organic tissues. Coming into contact with your bare skin, eyes, or mouth can cause rashes or burns.
  1. Ingredients that Drano contains can be detrimental to residential and water environments. Liquid waste will make its way into the sewage system, rivers, streams, and the ocean. It can cause plants and wildlife to suffer, contaminating food and water supplies.
  1. Drano can harm septic systems because they kill all bacteria, the good ones included. Typically, the “good guys” aid in the decomposition and break down the sewage in the septic tank. It means that using a bottle of this chemical cleaner for clogged drains can cause even more significant blockages than we had before we had dealt with an in-house clog.
  1. One extremely important reason to rethink using Drano is the harm it could cause to kids and pets. These creatures—not being able to read cautionary labels—are susceptible to accidental poisoning by household chemicals. 

Important: Wash the product off immediately after use. Keep your hands away from your face during and after the process. Keep Drano away from children and pets. Keep the phone numbers for local and national poison control hotlines in case of accidental spillage.

Frequently Asked Questions

Drano is caustic, so it can corrode and damage the pipes if it stays inside for too long. The same happens with any chemical drain cleaner left unflushed in the pipe.
If you don't want to invest in the menu of chemical products, make your own drain cleaner solution. Pour one cup of baking soda, two cups of vinegar, and a half-gallon of hot water into the toilet. You can add dish soap to help dissolve some obstructions. Allow the solution to sit overnight and then flush the toilet in the morning.
