I saw this Biocera laundry washing ball with ceramic pebbles at their road show counter, and bought home for a try.
This washing ball is said to be able to replace the function of detergent and softener when placed in our washing machine. It is able to clean, sterilize and deodourize our clothes and laundry by "activating" the water during the washing process.
It is said that each of this soft rubber ball with ceramic pebbles inside can be used for up to 1,000 washing cycle, which is at least a few years for normal household use. We only need one ball for laundry up to 6kg, and two balls if the laundry exceeds 6kg.
Here are my 2 Biocera balls in my 9kg washing machine, ready to use.
I was told to immerse the Biocera balls with water for about 30 minutes before their first use. I found some small black particles in the water after the 30 minutes immersion. Perhaps this is the reason, or else the small particles might cause blockage in the washing machine drum.
