Mrs Martin’s Probiotic Mighty Oven Cleaner Concentrate


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.

This is a concentrate. Dilute 1:14 with tap water to get Ready To Use strength soap. This soap can be further diluted, depending on use.

Usage Mighty oven cleaner

Not only use this product for oven cleaning but also any surface where there is any fat and oily residue.

For tougher jobs

Love Mighty for tough stains on walls, surfaces and even on clothing! I also love the fact that it is a concentrate, I can get a small bottel and it lasts a long time.

Yes, it is great as a stain remover on clothes! And don't the concentrates just make sense? Thanks, Liza.

Mighty soap

Mighty cleans greasy pots quite well, it has to be used directly on surface and not in washing up water to work. I tried it on sponges and cloths but doesnt really work so well there. I am still getting used to working with this environmentally friendly product.

Thanks for the review, Jenny. MIGHTY works best if sprayed directly onto the oily surface, left for five minutes and then scoured before rinsing off. Because we do not use harsh chemicals, you might need a bit more elbow grease than for conventional oven cleaners. We think you'll agree the benefit to your health and that of the environment is worth the extra effort!
