It took several days to work but has completely transformed my home from drain smell hell. Thanks Microbz

Drain cleaner
1 litre
Our probiotic drain cleaner naturally digests organic blockages and eliminates odours to keep your pipes clear and free-flowing without harsh chemicals.
Choose your plan:
Key benefits
Clears organic blockages: beneficial microbes actively digest the fats, oils, and grease (FOG) that cause slow-running drains and stubborn clogs.
Eliminates odours: instead of covering up smells, our formula breaks down the decaying organic matter inside pipes to stop foul odours at the source.
Maintains healthy pipes: regular use creates a biological film that keeps pipes clear and prevents new buildup from sticking to the plumbing.
Safe and non-corrosive: unlike harsh chemical drain openers, our natural formula won't damage your pipes, seals, or septic systems and is safe for the home environment.
Long-lasting action: microbes continue to work deep within the drainage system long after the initial application.
How to use
Use regularly to maintain your septic and drainage
systems.
For wastepipes dilute 1:4 with water and add 50ml of the
diluted solution to sinks, shower and bath outlets weekly to
keep wastepipes clear. Leave overnight to allow microbes
maximum munching time.
For blocked drains dilute 1:4 with water and apply daily
until blockage and smells are gone, then maintain regularly
as above. If blockage persists, use a stronger solution either 1:2 with water or undiluted. For septic tanks use 1 litre per m3 tank capacity for one-off treatment. After 2-3 weeks the microbes should have become established in the system.
For regular weekly dosing, flush 250ml of drain cleaner
(undiluted) per person into your system.
Ingredients
Purified water, sugar cane molasses, beneficial microbes (lactic acid bacteria and photosynthetic bacteria, yeasts).


How Do They Work?
How microbes work to clean your home
By restoring the balance of positive microbes in your home, harmful bacteria are crowded out, leaving your home better protected and your surfaces cleaner for longer.
Studies show that microbial cleaners reduce pathogenic activity more effectively than chemical cleaners even after 24 hours.
How to use them?
Simply mix 10ml of our concentrate with water in a 500ml spray bottle, and spray away. Leave for a couple of minutes so the microbes can get munching, then wipe and be amazed by how all surfaces and spaces are fresh and sweet smelling.

It works x

I just use the product to maintain my off-line drain. Have used other similar products for several years - this one is more keenly priced than some and works just as well. The aroma is akin to cider or grain spirit distillation but you'll be relieved to know that I haven't been tempted to taste ! ! ? ?

I live in an extreamly old terraced cottage with a flying freehold therefore neighbours bathroom/drains are situated on my patio & directly outside my diningroom sun area .. I have always used drain product from Microbz in my sinks etc & have had no issues for many yrs .. Un fortunately this year there has been foul odour from my neighbours drain that went on for months & nothing he did from his end worked until i starting treating with my drain clear from Microbz .. within wks everything finally returned to normal & we are both much happier for it !!! Highly recommend.

Brilliant, will be back for more!

Love the idea, sadly didn’t work on our smelly drains with one bottle and would be expensive to keep buying more bottles over the course of a month. I can imagine that if you do have the budget to do that though, that you could clean your drains in an eco way

Just love this product! With just one application the lingering repugnant odour from the drainage was dispelled.

Keeps drains and pipes clear, and good to know I’m not chucking toxic chemicals down the plug holes

A useful product for the maintenance of 'offline' drains

Store owner replied: Thank you, Mike!
I spray all the kitchen and bathroom plug holes, the shower trap and the toilet. The foul odours stopped and I noticed a kind of slight smoky odour which is pleasant. After using it regularly for two weeks I noticed all this gunk exiting the outside drain pipe which was obviously eaten and dissolved by the microbz so we are very happy with this product.

Store owner replied: Thank you! This is exactly what the microbes do! They are amazing 🤩
Amazing stuff. Have been pouring down sinks at night & they are gleaming in the morning. Drains smelling better too.
Lesley W. 5/5 Verified
Very Happy and would definitely recommend! I had a blocked shower for weeks, I kept putting bleach down it ( which I hate) but it did nothing. I’d usually just turn to a supermarket drain cleaner ( again which I hate) but when I saw Microbz ad on insta I thought it would be nice to try something natural and support a small business. To be honest I wasn’t expecting miracles but I got them! Within two standard uses my blocked shower was cleared!! Super happy 🦠💚🌱

FAQs for probiotic cleaners
How does the probiotic drain cleaner work?
Our cleaner uses beneficial microbes that naturally "munch" through organic matter like fats, oils, and grease. Instead of using corrosive heat, it biologically digests the buildup that causes blockages and bad smells.
Is it safe for septic tanks and older pipes?
Yes. Unlike harsh caustic cleaners, our formula is non-corrosive and completely safe for all plumbing, seals, and septic systems. It actually helps maintain a healthy septic tank by supporting the natural breakdown process.
How do I use it for regular maintenance?
To keep wastepipes clear, dilute the cleaner 1:4 with water. Add this solution to your sinks, showers, or baths weekly. For the best results, leave it overnight to give the microbes maximum time to work.
What should I do if my drain is actually blocked?
Dilute the cleaner 1:4 with water and apply it daily until the blockage and smells are gone. If the blockage is stubborn, you can use a stronger 1:2 solution or use the product undiluted. Once clear, return to the weekly maintenance routine.
How much do I need for my septic tank?
For a one-off treatment, use 1 litre per m³ of tank capacity. It usually takes about 2–3 weeks for the microbes to become fully established. For regular weekly dosing, flush 250ml (undiluted) per person into the system.
