How To Clean Bathroom Black Mold From Shower Caulking?

Step 1. Prepare The Cleaning Solution

Take a bowl and pour some baking soda into it. Add vinegar afterward. Continue adding vinegar to the point you get a cream-like mixture. Once it’s done, dip a brush into the mix and run it over the mold-affected area to apply the solution.

Step 2. Cover The Paste-Applied Region With Tape

After applying the paste, seal the region by placing a piece of tape over it. You can also use plastic wraps to cover the area. Exposure to humidity will compromise the effectiveness of the mixture. So, you have to cover it up for desired results. Keep the tape on for 120 minutes, at least.

Step 3. Remove The Tape

After the waiting period is over, take off the tape or the plastic covering. By now, the solution will dry out. Wipe off any leftover paste with a dry cloth or paper towel.

Step 4. Use Anti-Fungal Spray

Spray anti-fungal spray over the caulk and leave the area untouched. No need for coverings this time since the spray needs to come in contact with air for a faster effect. We recommend using the MOLD ARMOR FG502 Mold and Mildew Killer + Quick Stain Remover. Apart from eliminating the mold, it will take care of other grime and stains. 

NOTE: If you are too late to act, the mold spreads so deeply across the caulking that you won’t be able to do much other than removing the discoloration and the smell. The mold will be back in a few months again. In this case, you can consider replacing your entire caulking. It doesn’t take up much time, and it’s not expensive either.

That said, you can expect an effective deep clean using a high-quality anti-fungal product like the one we have suggested above.

Step 2. Scrub The Grout

Since grouts and tiles are tricky places, you will need something special to clean all the nooks and crannies. Get a power scrubber like the Rubbermaid Reveal Power Scrubber. It comes with an oscillating head that cleans the difficult spots. Run the scrubber across the grout for a few minutes. It will take care of two-thirds of the mold infestation. 

Step 3. Prepare A Baking Soda Paste

Take half a cup of baking soda in a bowl and add three or four tablespoons of water to it. As a result, you will get a baking soda paste that can remove odor, stains and sanitize your kitchen and bathroom. It’s cost-effective and has no health hazards involved.

Step 4. Spread The Paste

Now, take the scrubber and put its head into the pate. Roll it around a couple of times so that it grabs a spreadable portion of the paste. Take it out and run the scrubber across the grout again. Keep on doing this until the grout comes off completely. It should not take more than 5 minutes.

Step 5. Use Anti Fungal Spray

Rinse off the paste with water and let the area get dry. Afterward, spray the grout with anti-fungal spray. Leave it for 5/10 minutes so that the solution can take effect before drying off in the air.

How To Clean Bathroom Black Mold Behind Shower Tiles?

Step 2. Use Vinegar

After the bleach dries off completely, apply vinegar to the tiles. This will address the tiniest fraction of mold that you had missed earlier. Alternatively, you can use borax or ammonia.

Step 3. Apply Primer

Now, apply a primer like the Rust-Oleum Mold Killing Primer. It will kill off all fungi, bacteria, mildew, and other detrimental entities. Therefore, you won’t have to worry about mold growing behind the new set of tiles you are installing.

How To Clean Bathroom Black Mold From The Shower Drain?

Step 1. Pour Vinegar

Take off the drain cap and pour vinegar inside the drain. Pour around the edges so that the vinegar drips down the drain walls. Don’t pour it down the middle because the vinegar will not come into contact with the drain walls. So, it will be a futile effort.

Step 2. Use A Power Scrubber With Extension Handle

Grab a power scrubber that offers an extension handle. Dip the scrubber head in vinegar and send it down the drain. Scrub the upper drain walls and move on to the later parts by slowly lowering the scrubber. Scrub as far as the handle reaches.

Step 3. Flush With Warm Water

Drop a bucket of warm water down the drain. In doing so, the residual vinegar will wash away along with the black mold.

Step 4. Use Anti-Fungal Spray

Come back a few hours later to spray some anti-fungal substance inside the drain. Of course, you won’t reach far down the drain. So, just spray around the opening. 

Black mold that lies deep in the drainpipe will not do you as much harm as the ones that are nearer to the drain opening. Hence, the anti-fungal spray will keep that section of the drain safe from new mold infestation.
