It is essential to clean products you use, especially when used to make ozonated water for consumption. When using the Tri-Oxy FRESH for a period of time, the diffuser stone may become discolored. The reason for this is that the water you ozonate is full of hard minerals.
The diffuser stone is still usable when it is discolored. However, because the stone is porous, it may become dirty or clog up. Use a stiff bristle brush to rigorously scrub the stone.
This is a simple way to clean the diffuser stone, so you can continue to enjoy your on-demand ozonated water.
