Apply the solution directly to the mold .
Let sit for 10 minutes, then rinse with cold water.
If possible, scrub well with an unused toothbrush.
If a single application is not enough to remove black mold from silicone in the bathroom, apply it a second time and see how everything disappears.
Remember that to avoid the formation of mold in the bathroom, it is important to ventilate the room, dry the surfaces well after showering, and control the humidity level.
