    It's hard to tell from your picture, but it looks like mold or more likely mildew. If that's the case, clorox should remove it. If you've already tried this, maybe give a little more info about the spots themselves--how long they have been there, what products or methods you have already tried, etc.

    Saturate a cotton ball with a bleach cleaning spray. I used Clorox bathroom tub cleaner. Then, leave the cotton balls on each spot overnight. By the morning, it will be gone. I used this tips a few times so far. Make sure no one takes a shower while these are on the spots, it will dilute the cotton balls.

    Try Mr clean white sponges. They are in a box & not expensive.

    looks like mildew or mold under the caulk, may need to take caulk off, spray with bleach or mildew cleaner, let it dry for a day or two , very important that its completely dry, then recaulk

    Try soaking with hydrogen peroxide. Let sit awhile and then rinse off with hot water. If that doesn't work, try the same with white vinegar. If the black is actually under caulking, you may have to remove the caulking first. Good luck!

    I would try Bleach, it looks like mold. Bleach should work; you may have to let it soak for a while.

    I use "The Works" toilet bowl cleaner! Works wonders every time! Just squirt "The Works" on the spots ... let it set for around a minute then I use a scrub brush and no need for elbow grease ... rinse with water ... spots are gone!

    Clorox gel pen works great. Squeeze on and let it sit for a while

    I use bleach on mine and it works great, use a "thick" bleach Domestos or the like and pour straight from bottle and leave for a while and wash off, with a small amount of mould as in your pic I would just dab the bleach on with a small paintbrush. Good luck

      the mold has gotten under the ilicone seal, your best bet is to remove an replace the silicone seal but carefully clean the area under the whole silicone seal with bleach before adding the new

    that is mold and that means there is moisture behind the panels, black mold is not good to breathe in. Are you running the ceiling when using the shower? Black mold will not go away, you have to address the problem. That means removing panel surround and pulling the damage drywall.

    I'm guessing this is a laminate wall. If so, chances are whoever installed it, used a black tar-like adhesive. It appears to me, the tar is seeping out. If you use bleach, and it is mold, it will go away, but if it is tar, you will need to dig out the caulking and recaulk. If it is tar, speak to the hardware man & explain your situation. He can make the best recommendation for the right caulk.

    This looks like mold if bleach doesn't work it's inside of the chalking you need to cut it out and rechalk it.
  • Ditto what Sherrie said :)

    Bleach or any cleaning product that removes mold. Apply and let it sit for as long as it takes.

    Soak cotton balls in bleach and place on spots for a couple of hours. Worked for us.

    If it is black mold, I prefer tea tree oil at full strength instead of using bleach.

    I think you've caught it earlyish and seems to be absorbed into your caulk. I've had this problem in one of my bathrooms and I just cut through the caulk to see how far in it has gone, then clean whatever black is left and repair the caulking

    Tilex mold spray. No scrubbing involved. Spray and leave alone.
