If you don't want to take the time and the expense to remove and replace your shower or bathtub caulking that is currently moldy, then this is a great way to remove the mold and mold stains that is very affordable and easy! Plus, it works amazing!
So, if you have a bathtub with caulk that looks like this, follow along!
You'll need cotton balls, gloves, water, and bleach. Eye protection and a ventilation mask also recommended.
Mix water and bleach together in a small dish, using only a little bleach. Open the window, turn on the fan, and wear gloves!

Dip a cotton ball into the bleach water and then apply the wet cotton ball directly to the caulking around your tub.
If you have moldy spots in the vertical caulking of your tub, stretch out the cotton balls a bit first before dipping them in the bleach water. Start with the highest part and then work your way down as the liquid dripping down will cause the ones below it to fall.
Let the cotton balls stay on the caulking for about 2 hours. Remove one and see if the mold is gone. If not, wait another hour.

If looks good, remove the cotton balls and dispose them in the trash.

You should now have beautiful caulking!
