A clogged toilet is both unsightly and highly unsanitary. It disrupts proper water drainage and eventually leads to off-putting odours.

Handheld plungers and cleaning agents, like baking soda and vinegar, usually do the job for unblocking toilets. But what if you’re out of these essentials? Well, a trusty bottle of chlorine bleach might just save the day.

Aside from vinegar and baking soda mixture, applying bleach is one of the easiest and cheapest methods for unclogging a blocked toilet. You can easily find a bleach bottle in your storeroom or laundry room.

However, there are different ways of using bleach to unclog your toilet, and we’ll discuss these methods today. But first, let’s find out how bleach works to block toilets.

How Can Using Bleach Unclog Toilets?

Bleach is a common chemical agent used domestically to clean and remove stains and is one of the famous DIY toilet unclogging ideas. It is sold under several different brand names. Chemically speaking, liquid bleach is the dilute solution of sodium hypochlorite.

When it comes to unclogging toilets, bleach acts as a disinfectant that breaks down waste build-up. It releases oxygen molecules, which oxidise and break down the waste and stains. This makes it easier to wash them away, keeping your toilet free-flowing.

Commercial bleaches also have antimicrobial properties, so they’re perfect for sterilising your bathroom. They help stop the growth of algae, bacteria, and viruses. In short, regular bleaching keeps your bathroom hygienic and clean.

What Will You Need For Unclogging Toilets With Bleach?

Before you get started with bleaching, make sure you’ve got what you need. Grab one to two cups of liquid bleach and about two gallons of hot water. You’ll need these to flush out the bleach as you unclog your toilet.

You will also require protective goggles and latex gloves, as diluted bleach can lead to severe chemical burns. Once you have all these items, you can proceed with the bleaching process.

Methods Of Using Bleach To Unclog A Toilet

1. Using Only Bleach

If you use bleach only for unclogging toilets, do not forget to wear rubber gloves and protective goggles. The gloves protect your hands from chemical burns, while goggles guard your eyes against splashes.

Now, pour one to two cups of liquid bleach inside the toilet. If there’s more water in the bowl, you might need to increase the amount of bleach. Since more water in the toilet means more clogging, you must add more bleach.

Once poured, let the bleach work for 10 to 15 minutes, and then flush the toilet. Your toilet will perhaps be as good as new. However, always remember to turn on the exhaust fan in your bathroom while using bleach. It helps in proper ventilation and prevents inhaling any toxic chemical fumes.

2. Using Bleach And Hot Water

If you’re not satisfied with using only bleach to unclog the toilet, add some hot water to the mix for a better result. Add two cups of liquid bleach to the toilet bowl and leave it to work for about 10 minutes. After that, add hot water to the bowl to fill the toilet halfway. Let this liquid bleach and hot water mixture rest for five to seven minutes. Flush the toilet tank multiple times to wash off the mixture and ensure your toilet is clog-free.

Using drain cleaners or a plumbing snake might be necessary if the clog persists, as these methods target tougher blockages within the plumbing system. Always wear rubber gloves and protective goggles during such tasks, as the chemical reaction from bleach can create harmful fumes. Ensure the bathroom is well-ventilated for safety.
