Absolutely FANTASTIC! I used it as instructed (left overnight) and was amazed as it was able to remove all the build-up and limescale at the bottom. I did use a brush to scrape and remove it when rinsing, but it never helped with other products I used. Looking at other reviews, I was concerned about a strong smell but didn’t notice any strong smell despite having it left to sit for hours!
The only question I have is how safe is it for the ocean and aquatic life?


    What a wonderful review of our toilet cleaner.
    Thank you very much!
    All of our products are carefully formulated so that they are not classified as harmful to aquatic life.

SUPER! I live in a soft water area (Scotland) and this natural cleaner works so very well. I personally like the smell and would welcome bioD exploring adding a range of oils perhaps, like their other products?


    Hi Paul
    Thank you for your super review.
    We are looking at fragranced options for this product so fingers crossed this will be available in the future.
    Thank you again

This works ‘ok’ but its not excellent. I find its good at maintaining if used regularly but if any limescale or build up at bottom of bend (like it did when I was away and no one cleaned it!) it just doesnt quite do ‘the job’ and end up resorting to other brands. But if you keep on top of it this does well.
Have Bio-D looked at a cistern tablet type option?


    Hi Lisa
    Really appreciate your feedback regarding the toilet cleaner.
    I will send your comments to our product development team to see if this is something we are looking to add to our range in the future.
    Thank you

Seems the cleaning well, but smells like vinegar so not the nicest smell to linger in the bathroom. Will try adding some scent to it.


This is the ONLY natural toilet cleaner I found that actually works and doesn’t leave you with smelly pipes after awhile like others can. However I just can’t stand the strong ginger smell. Even after it’s been made lighter. Would prefer a pine type scent or maybe lemon/citrus.


What a nice smelling toilet cleaner. This is a very powerful yet nice smelling toilet cleaner removes limescale and other stubborn dirt cheap to buy.
