All about Bio Enzyme

What is Bio-enzyme?

Bio Enzyme is a natural cleaner made with citrus peels. It is a complex mix of organic substances such as proteins, salts and other by-products of naturally occurring yeast and bacteria. It effectively breaks down waste and helps remove stains, get rid of harmful microbes and it smells great. Bio-enzyme thus is a great alternative to chemicals commonly found in cleaning products such bleach and phenyl.

Chemical cleaners not only pollute the environment in the form of plastic packaging, they also leave chemical residues. This slow accumulation of toxins is harmful to us, our children and pets. If you can’t be bothered about the environment, do it for your personal interest and the safety of your loved ones.

Is it really worth putting in all this effort to make just a ‘cleaner’?

YES! YES! YES!

A thousand times yes!

Bio enzyme is not ‘just-a-cleaner’. I’ve been using it for almost all my cleaning needs but I find new uses for it every now and then. Here’s some ways you can use it –

  1. Cleaning and disinfecting – Think floor (except marble), tiles, bathrooms, toilet bowl, stovetop, kitchen counter, windows, refrigerator, cabinets, cars and surfaces.
  2. Dishwash – Mix with soapnut water to make your own all natural, non-toxic dishwash.
  3. Produce wash – Neutralize harmful fertiliser and pesticide residues by washing fruits and vegetables in a water and bio-enzyme solution.
  4. Fabric conditioner & stain remover – Throw 1/4th cup in the washing machine along with a bag of soapnuts and have delicious smelling clean laundry.
  5. Personal care – Bio enzyme can be used as a hair conditioner. You can augment with glycerine, soapnut solution and essential oils to make body wash, shampoo and face wash.
  6. Deodoriser – Add 1 part bio-enzyme to 3 parts water to a spray bottle and remove odours from shoes, shoe cabinets, under the sink cabinet or just spritz around the room for a citrusy fragrance.
  7. Limescale remover – Use the pulpy residue to scrub taps and other metal surfaces.
  8. Pest control – It does not kill insects but bio-enzyme can be effectively used to repel cockroaches, mosquitoes and ants. Add 15ml bio-enzyme to 500ml of water in a spray bottle. Combine with neem oil if you’re faced with persistent critters.
  9. Garden pest control – Spray a very diluted solution of 1: 1000 on plants to repel pests like white flies, mealy bugs and spider mites.
  10. Natural fertiliser – Bio-enzyme also works wonders as a bloom nutrient. Mix 30 ml bio-enzyme in 2 litres water and feed directly to the soil.
  11. Pet shampoo and cleansers – Bathe your pets with a diluted solution for an allergy-free experience.
  12. De-clog drains – Pour directly into the drain to get rid of any clogs and blockages.

Know of more uses? Let me know!!!

Bio-enzyme has an amazing capacity to rejuvenate contaminated water. One litre of bio-enzyme can de-contaminate 1000 litres of water. Each time you pour this miracle solution down the drain, you are actually helping in purifying groundwater.

How can I make bio enzyme?

Citrus peels (orange, lemon, lime, pineapple, mosambi), water, jaggery and a plastic container is all you need.

The ratio 1:3:10 – Jaggery to Citrus Peels to Water

Take an air tight container that’s big enough to accommodate the solution and still have a 10 – 15 % space left empty. Mix these three ingredients in that container. Bio-enzyme is quite forgiving so rough measures work perfectly fine. Put the lid on, label it with the date of creation and leave it in a dark place.

For the first week you should open the lid to release gases built up in the empty space. From second week onwards, the gas activity will reduce a bit and you need not open every day – you can open every other day.

How long does it take?

Usually, it takes about three months for the Bio Enzyme to be produced. You can expedite the process using one of these two options –

Option 1: Add 1 teaspoon baker’s yeast to produce bio enzyme in just 20 days.
Option 2: Add leftover pulp of a previous batch to produce bio enzyme in 30 days.

I hope you found this helpful and will make your own miracle-juice soon.
