Mrs Martin’s Probiotic Mighty Oven Cleaner 5L


We made this item more expensive to encourage our clients to consider concentrates. Shipping around water does not make sense when you have water at home!

In a cleaning regime where you use microbes to do the dirty work, this is your oven cleaner. The millions of indigenous microbes in this bottle are your allies against muck and grease. On contact they will release enzymes to break down tough dirt and digest bacteria that cause bad odours. After you have finished cleaning, some microbes will be left on the surface to keep watch against undesirables. Those microbes you pour down the drain will continue to remove nasties like nitrates, nitrites and ammonia from the waste water, the natural way. Everything else in this bottle is non-toxic and degrades within 28 days. Even the colourant and fragrance are hypo-allergenic and natural so that you can rest assured you are doing no harm. Neither to yourself nor to the environment. Fill your 750ml spray seven times.

Best product

Cannot live without this product. A simply spray in cooking pans and all oil/fat is easily wiped away. Never mind what magic it does in the oven. So glad to be free of toxicity. This product is a game changer.

Music to our ears. Thank you so much for this review, Joanne.

I love this product

After I saw MIGHTY is specifically designed for greasy spots, I have used this product on my stove and other grease surfaces when needed. Highly recommended.

Thank you, Tanya!

Elmarie S.
Mighty Awesome!

Just a superb product! Been using it for over two years and will use nothing else.

We are mighty pleased to hear that, Elmarie! Thanks for taking the time to write.

Mighty soap

It does not clean surfaces as I expected it to do.

Sorry to hear that, Franci. Sometimes less chemical does mean more elbow grease. May we suggest that you leave MIGHTY on the surface for five minutes before you start scrubbing? That gives the little chemical that there is, enough time to work.
