Toilet Cleaning with Dr. Bronner’s

Every so often I get the joy of sharing subjects very close to my heart. This is not one of them.  

How to use Dr. Bronner’s products to clean toilets is a common question I get, and hopefully a regular task for all of us.  

As I say in the video, toilet bowl cleaner was the last conventional cleaning product I gave up in my green transition. I liked the color, I liked the smell, I liked the peace of mind. Yeah, it sounds like I was a little too cozy with my toilet bowl cleaner. 

Even though cleaning ingredients don’t have to be listed on a label and rarely are, the required hazard statements you find readily on bowl cleaners give you enough of an idea that this is not-nice stuff. Go ahead and read a few. I’ll wait. 

Eventually, I couldn’t ignore the fact that toilet bowl cleaner is one of the harshest of household cleaners. All it would take is one “Oops” from me, or a kid or a dog getting somewhere they’re not supposed to, which happens, and I’d have a real problem. Plus I have a septic system which relies on helpful bacteria and enzymes to work. Killing them all with bleach is entirely counterproductive. 


There is more than one way to do this. Do you prefer Sal Suds? Castile Soap? Pick whichever method, whichever product you like best and gets the task behind you. 

To begin with, if you’d like, turn off the water to the bowl and empty with a flush. This is entirely optional. Many household toilets have a valve at the wall that you can twist. Emptying the bowl lets the cleaner sit on the walls of the bowl without being diluted in the water. 

Method 1: Make an All-Purpose Spray with Dr. Bronner’s Castile Soap (1/4 c. [60 mL] in a quart [1 L] of water) or Dr. Bronner’s Sal Suds Biodegradable Cleaner (1 Tbsp. [15 mL] in a quart [1 L] of water) with 20 drops Tea Tree essential oil (optional). Spray the bowl thoroughly and brush with a toilet brush. 

Method 2: Squirt a very small amount of the undiluted Castile Soap or an even smaller amount of the Sal Suds directly on to the toilet bowl brush. Brush the bowl thoroughly. 

Boost for Methods 1 or 2: For extra scrubbing, sprinkle baking soda onto your toilet brush before scrubbing. 

Method 3: Science up a batch of GIY Soft Scrub with the Castile Soap. Squirt that around the bowl, under the rim and brush well. 

Whichever method you choose, once you brush the bowl, let cleaner sit there for about 10 minutes for maximum effectiveness. Then give the bowl a final scrub, turn the water back on if you turned it off, and flush. 

Let’s wrap up with a little relevant middle school humor. Welcome to my world. 

The police station toilets were stolen. Investigators have nothing to go on. 

Ok. I’ll stop.  

Why do you never hear a pterodactyl go to the bathroom? Because the P is silent.

Melissa says:

Is the sal suds all purpose cleaner gentle enough to use as a cleaner on a glazed bathtub?(landlord asked if we could do that)& it’s also strong enough to tackle hard water in the toilet?

Lisa Bronner says:

Hi Melissa- Sal Suds is gentle enough for a glazed tub. You can mix up an All-Purpose Spray with 1 Tbsp. Sal Suds in a spray bottle with a quart of water. Spray and wipe with a damp cloth. Sal Suds is find to clean hard water build up too. For stubborn stains, sprinkle a little baking soda on a brush for scouring action.

Lisa Bronner says:

Hi Denise – No, Sal Suds is not an enzyme cleaner. It is a mild detergent surfactant – which means it bonds with dirt and grime and carries it away. It doesn’t break down elements as enzymes do.

Jennifer says:

Will this solve the toilet bowl ring, because that just never seems to go away with more eco-friendly products : / Help!!!

Lisa Bronner says:

Hi Jennifer- Because toilet bowl ring is mineral deposits, go with one of the scrubbing options of either baking soda or GIY Soft Scrub. Let it sit for the full 10 minutes, then scrub again.

Diane Martinson says:

I can see how these three methods work without water in the bowl but what about if you have to leave the water in, wouldn’t the soap get too diluted to work well? Besides tea tree oil is there another essential oil that would disinfect as well?

Lisa Bronner says:

Hi Diane- If you leave water in the bowl, perhaps use a tad more soap. But because our soaps are very concentrated, they work very well. No other essential oil has the same microbial properties as Tea Tree, but it’s the soap that is really doing the cleaning here. Soap latches onto germs, dirt and grime and washes them away.

Catherine Harper says:

Thanks Lisa. Love these tips. Sal Suds is my go to kitchen and dish soap, and Peppermint Castile Soap replaced all body washes in my shower years ago. Haven’t used them for toilet cleaning but will be trying this for sure!

Brenda says:

Love the video! I’ve been using Sal Suds and tea tree oil for some time now. No more chemicals in our household. Thank you Lisa.

Diane Blanchard says:

Definitely going to try this! I’ve been looking for a safer bath cleaner. Thx Lisa!

Chris says:

Hi Lisa,
Love all you products! My question, is tea tree oil poisonous to dogs. I have four little ones and read where tea tree oil in a diffuser poisoned a pet. Thanks Chris

Lisa Bronner says:

Hi Chris- At too high of a concentration, it would very well make a dog ill. But the essential oils in our soaps is 2% – a very small concentration. Our soaps are further diluted when used for housecleaning and then wiped off with a damp cloth. I don’t know about the diffuser, but really strong scents can be impactful to pets.

Kelle L Standley says:

Argggggg, the jokes are baaaaaad! However, I am considering giving up my toilet bowl cleaner for sal suds. Like you, I am also a bit too fond of the hazardous blue chemical goo I buy from the hardware store but have been loath to give it up. I will give sal suds and shot and see how that works out. Thanks again, Lisa.

Meinaz says:

I’ve made the soft scrub recipe and like using it. However it dries in the cap and I have to use a toothpick to unclog it each time I use it. I have it in a pull too squirt bottle like dish soap comes in. Think I’ll try the spray you talked about instead. Thank you.

Lisa Bronner says:

Hi Meinaz- If the soft scrub thickens up, add a few tablespoons of water to thin it out. I’ve also put it in a wide-mouth jar and scooped it out. But you’ll love the All-Purpose Spray – you can use it for countertops, sinks, baseboards and more.
