And know one likes mold right. It's not just gross looking growing on your bath tub but it's bad for your health. I know in this house it reeks havoc on Cohen. So instead of using a chemical such as bleach, try these tip.
Fill a spray bottle with straight white vinegar, saturate the area, and let it sit.
For more resilient mold, try mixing of two teaspoons of tea tree oil and two cups of water. Nearly as effective as tea tree oil, grapefruit seed extract (20 drops mixed with two cups of water) will do the trick without the smell.
