Cleaning drains and pipes with bokashi tea

Bokashi tea: It’s OK to throw it away

This isn’t a phrase I use very often! I am a huge advocate or reduce, re-use, recycle… repurpose, refuse…. anything to mean that ‘stuff’ doesn’t need to be thrown away. But in the case of your bokashi compost tea, throwing it away can be the best thing to do.

Bokashi tea can make a great fertilizer for your plants (indoor and outdoor). Read more about using bokashi tea here. However, over the colder, winter months your plants probably don’t need as much feeding (and there are days when even the most dedicated gardeners would rather stay indoors and doesn’t fancy feeding the garden).

So, if you don’t want to (or need to) use the bokashi tea for fertilizer, what do you do with it? Throw it away! Down the drain, to be precise. You can feel good about doing this, as it is completely harmless to the environment (in fact its beneficial), and doing so will very likely prevent the headache of clogged pipes down the road.

Common causes of blocked drains

If you’ve ever had to have your blocked drains professionally cleaned, you can appreciate the headache that it causes.

  • Within the house, the common cause is buildup of cooking debris (mainly grease and oils) from the kitchen sink. This slowly builds up over time as a kind of living sludge.
  • Elsewhere, a small imperfection in the line can cause something as small as a hair to get caught, and the blockage will start to build up from there.
  • Outside of the house is where the more serious problems occur. Tree and plant roots, in their constant search for water, find their way into the lines and proliferate. Older houses are most at risk of this, as they have clay or cast iron pipes which are prone to cracking. Tree roots find these cracks, and pry them apart.


  • Other homes, in rural areas, have septic tanks and septic fields to worry about. These can easily become clogged or overfilled if the health of the tank or field is weakened.

How bokashi tea helps your drains and septic systems

Bokashi tea is made of juices from your food scraps plus everything it picks up on the way as it drains through your kitchen composter; microorganisms from the bokashi process, water, organic matter as well as the by-products and waste from the bokashi bacteria. In other words… it is all natural and perfectly harmless to poor down your drain. In fact it can actually be good for your drains.

An easy and proactive solution to blocked drains is bokashi tea.

The microbes in bokashi tea work excellently over time to clean out sludge and organic debris from your pipes. And being acidic in its undiluted form, it deters plant roots from developing.

For your septic tank or septic field, the bokashi microbes will thrive there, and in doing so will break down the wastes. It will also help with odors that sometimes come back up the pipe into these homes.

How to use bokashi tea

No need to dilute the bokashi tea you can simply empty your tea straight down the drain.

  1. Simply put your bokashi composter into the sink and open the spigot.
  2. A very brief run of water down the sink afterwards will remove the bokashi tea smell from the room, and spread the tea down the line.
  3. Repeat as often as is needed.

If your drain is particularly blocked (and, if possible), don’t put any water down the drain for a few hours to give the bacteria chance to do their work.

Customer’s stories

Don’t just take our word for us. Here are a couple of stories that we have heard from Bokashi Living customers who used bokashi tea to save their problem drains:

During the summer I collect every drop of water from my house for my garden; shower, dish-washing etc. This meant very little water goes into my septic tank system. Without enough water, these septic systems start to smell…. bad! However, after putting just a cupful of bokashi tea down my kitchen drain the smell disappeared in less than 24 hours.

Mayne Island customer, 2015

I had great success using bokashi tea to unblock a drain filled with dog-hair. I simply put a cupful of bokashi tea down the bath drain and left for a couple of days. Voila, clear drain!

Vancouver customer, 2017

So you don’t need to feel guilty about ‘throwing away’ your bokashi tea down the drain. It is completely harmless to the natural environment and will actually be beneficial to your drains.

    Can I keep my bokashi tea in the fridge? I have 2 bokashi bins and a small garden. Can only use the tea for watering once a week? Your advise will be appreciated. Kind regards Ingrid

    • Nicki Casley says:

      We recommend using the bokashi tea as soon after you have collected it as possible. The benefits of the bokashi tea are from the microbes, and these will start to decline as soon as you collect the tea. If you are continuously bokashi composting, you should have a continuous supply of bokashi tea and therefore you should have some in your bokashi bucket when you do your weekly watering. If you are continuously bokashi composting, there is often no need to store the bokashi tea.

      Hope that helps.

    Can you bokashi tea mix with water the plant on a daily basis?

    • Nicki Casley says:

      Thanks for the question. Daily watering with bokashi tea is likely too frequent. Watering your plants with diluted bokashi tea up to 1-2 times a week during peak growing season is generally considered sufficient. The frequency of watering with the bokashi tea should be reduced during off-seasons and for plants grown in containers. And let your plants guide you. If they thrive on more frequent application of bokashi tea, then try increasing the usage.
      Happy composting 🙂

    I never can use my yea because it’s always clogged. Any tips? I was going to put cheese cloth on the interior screen. Or maybe a filter at the spigot inlet?

    • Nicki Casley says:

      Have you put the drain plate in the bottom of your bokashi composter, before adding the food waste? The drain plate should stop the spigot becoming blocked with food waste and just let the bokashi tea drain down into the reservoir at the bottom of the bucket. If your spigot is blocked then (next time your bucket is empty) you can spray water through with the hose. If this doesn’t clear the blockage, then you can easily disassemble (the spigot is just screwed in with rubber washers), clean and re-assemble the spigot.
