I have read that when mixed in water, sodium percarbonate gradually dissolves, leaving behind only water. However, I have recently come across this video which says that pre-used sodium percarbonate solution remains effective and can be used to clean/sanitise more equipment, as long as two days after initial use.
- Does sodium percarbonate really leave behind only water, or is there something else left in the water that means it can be re-used, as suggested in the linked video?
- When using sodium percarbonate, is it necessary to completely fill all vessels and leave them to soak, or can a smaller amount be used to rinse equipment? I would like to minimise water usage if at all possible.
