This is an experiment I've done in my apartment. I've decided to put the experiment to the test, because I wanted to use non chemical cleaners to clean my apartment, and also put some kitchen wastes into good use.
To give you a summary, I followed the simple "recipe" of 3 ingredients:
- 1 ratio of brown sugar (yeaps, it must be brown sugar);
- 3 ratio of fruit peels (you can also use fruit pulp, but I prefer using peels of citrus fruits and pandan leaves for better fragrance); and
- 10 ratio of clean water.
- Mix all 3 ingredients in a plastic container (plastic can expand and will prevent ruptures). I used an empty 5 liter water bottle.
- Tightly close the container with a cap, and let the fermentation process takes its course.
- Wait for 3 months. Mark your calendar!
- Do not fill the container to the brim, as you will be surprised with an overflow of the enzyme liquid, when you open the cap.
- For the first week or two, remember to slowly release the cap at least 2 times a day to release air from the container. I did not have any trouble with the fruit flies or fungus on the surface, as I screwed the cap tightly.
However, the garbage enzyme did no wonders on my bathroom tiles and yellowed grout. The tiles are clean, but I couldn't turn them sparkling white. I tried to mix the enzyme with the cleaning liquid, but it did not help much either.
Update: I have tried the mixture of baking soda with hydrogen peroxide (2 to 1 part), and it works great with the grout! You can get the baking soda at any supermarket, and the hydrogen peroxide at your pharmacy.
