Do you see black spots in the washroom while you shower? Or your bathroom’s grout has started looking rather grim, and it won’t come off? These are clear indicators of mold in the bathroom and you’d need the perfect cleaner for your bathroom. Mold can form in your shower due to many reasons. The major reason is that molds love moisture, and well, the shower is a moist and humid place. If it remains untreated, then it can cause serious health issues like allergies, respiratory problems.

They can even permanently stain your grout and sealant and are rather an eyesore in general. The first thing you should do is identify if the mold is toxic or not. If it’s toxic, you should get it professionally removed due to the dangers. But you’re in luck as most shower mold is non-toxic, and you can easily remove it yourself.

How to Clean Mold in the Shower

Mold forming in the shower is a common phenomenon, and I think everyone fights this battle at least once in their life. This article will help, so it’s your last march towards this grim enemy. There are many ways you can get rid of mold in your shower. Some involve chemicals, while some are entirely non-toxic.

Mold Removal with Clorox

If you’re like me and don’t want to spend hours making your shower elements mold-free separately, try this method. This method will save you time as it’ll get your shower tiles and caulking looking fresh in one swipe. All this under $5 too! The trick is to use Clorox toilet cleaning liquid. Yes, you heard that right: toilet cleaning liquid, specifically the one with clinging bleach gel.

Items you’ll need

  • Clorox Toilet Cleaning Liquid
  • Scrub brush (stiff)
  • Face mask
  • Safety gloves
  • Paper towel
  • Bucket of water


Step 1

Firstly, crack open your Clorox toilet cleaner and apply it directly to the affected areas. This will bleach out the target areas directly. Make sure that you run it along with the grout, and if you see drips (which is impossible to miss), it’s okay. Furthermore, if you have a tub, make sure to apply the cleaning liquid to its base as well.

Step 2

The next thing you want to do is cover up all the areas with cleaning liquid with a paper towel. By doing this, you seal up the cleaning liquid because otherwise, it’ll fall off. This also increases the efficiency of removing mold from your shower.

Step 3

After covering up the moldy shower with Clorox and paper towels, you will want to let it sit for 30 minutes at the minimum. One hour is good as well as the more time it sits, the better results you’ll get. If the moldiness of your shower is severe, you might want to leave it overnight for optimal results.

Step 4

Once you’ve let the cleaning liquid sit for the required time, get scrubbing. Make sure that the bathroom is well ventilated and you’re wearing protective gloves and a face mask. This is because you are working with bleach at the end of the day, and the fumes can be harmful. Also, make sure that you use a stiff tile cleaning scrub because soft-bristled brushes won’t get the job done. The grim should come right off.

Step 5

The last step is to rinse everything off with a bucket of warm water. Coldwater won’t do the trick, so you have to use warm water. After following all these steps, your shower should be nice and clean, and mold-free. If you want to reduce the chances of regrowth, spray the shower area with white vinegar. Additionally, try to keep your bathroom as dry and humid-free as possible, so you don’t have to deal with this again.

Non-Toxic Mold Removal

If you think that treating your shower mold with chemicals is too much, we’ve got you covered. There are many non-toxic materials that you can use to clean moldy showers. I’m pretty sure you’ll have the tools in your pantry somewhere. Hydrogen peroxide, white vinegar, and baking soda are some of the most common non-toxic cleaning ingredients.

Hydrogen peroxide is naturally antifungal and antibiotic, making it perfect for removing molds from your shower. Baking soda not only kills mold but also absorbs moisture. This is perfect because the reason that you have mold in your shower in the first place is because of the humidity. Vinegar, on the other hand, inhibits the regrowth of molds while also killing spores.


  • Water
  • Hydrogen peroxide
  • Baking soda
  • Undiluted vinegar
  • Spray bottle
  • Scrub brush


Step 1

Take one part of hydrogen peroxide and mix it with one part of water. Or you can take one tablespoon of baking soda and mix it with water in a spray bottle. Take any of the mixtures and spray it directly onto the mold in your shower and let it sit for a few minutes.

Step 2

After you have let any of the two mixtures sit on the moldy shower surface, gently scrub it using a scrub brush. You can use a toothbrush to get to those hard-to-get corners (make sure no one uses that toothbrush again). Once you’ve scrubbed the grum away, rinse the treated area with water.

Step 3

This step is more of a precautionary step rather than a removal one. After you’ve cleaned your moldy shower, spray it with undiluted vinegar. Let the vinegar dry completely, and this should prevent the mold from growing there again.

Other precautionary steps you can take is keeping the shower well ventilated and dry. It’s a bit of a stretch, but you can wipe the tiles of the shower dry after taking a shower. You can also spray vinegar every other week, so the mold doesn’t even think about returning.
