  • Mold can grow in the grout. That is one of its favorite places.
  • It can grow inside the window frame if your window is IN the shower like mine is.
  • It can grow around the drain and on the drain plug.
  • Mold can grow on the shower caulking.
  • It can grow in the door tracks if you have doors.
  • Mold can grow under shampoo bottles, bars of soap, shaving cream bottles, etc
  • While not technically a part of the shower, mold can grow on a shower curtain.

Mold can also grow behind shower tiles and on the wall but this is due to a leak behind the shower and not from water in the shower typically. The exception is if your grout is old and cracking. Then water can seep behind the shower tiles allowing mold to grow.

But, now I can remove mold in seconds.WAY more effectively than bleach too!

It is so simple!

Types Of Stone Finish

Before we jump into the stone tile cleaner for a shower, it is important to understand and recognize the type of stone finish

  • Polished: A polished surface is kind of a glossy surface. It highlights the color and markings of the surface and reflects light
  • Honed: This type of stone has a satin-smooth surface and has a meager reflection of light. This type of surface is generally used for stairs, floors, treads, and other locations where heavy footfalls wear off the polished finish.

I wrote a whole post about removing black mold from shower caulking, though my bleach method has been critiqued for not actually doing more than removing the stain and color of the mold. And the mold did come back 6-9 months later.

You can see my video tutorial about how I did it though:

This is because bleach is no longer considered to be the best way to remove mold. It is only effective if the mold is on a non-porous material like tile, bathtubs, glass, and countertops. It doesnt reach the mold growing underneath the surface. Also, bleach can damage the materials it is used on as its a harsh, corrosive chemical. The fumes are strong and harsh and it must be handled with gloves.

But, it does do a great job at removing the mold stains, but the mold isnt truly killed. If you want to get rid of the possibility of future mold growth, bleach isnt going to cut it.

You can instead use vinegar, baking soda, ammonia, oxygen bleach, borax or hydrogen peroxide.

I, however, have not been able to find many tutorials on how to use these products specifically for cleaning moldy caulking in bathrooms, so if anyone has tried using them, with success, Id love to know! I tried making a paste of water and OxiClean and slathered it onto the moldy caulking, but it did absolutely nothing. It dried out shortly after application and didnt remove the mold or the stains at all.

Adding new caulk is a great way to spruce up that moldy shower.

    Natural stone materials like slate, limestone, granite, marble, and onyx come in a wide range of colors and patterns to suit a variety of bathroom designs. Soapstone, travertine, and granite work best in showers because they are less porous compared to marble.

    The hardest part about cleaning a natural stone tile shower is keeping the white, cloudy soap scum buildup under control.

    It may seem like the right idea to use acidic cleaners like vinegar and ammonia to dissolve stubborn product buildup and hard water deposits. These have extreme pH’s that will eventually break down any sealants, scratch stone, and eventually lead to discoloration.

    Natural stone should be cleaned once a week with a pH-neutral cleaning product like Simple Green All-Purpose Cleaner. The powerful cleaner dissolves tough soils and buildup without damaging your beautiful stone surfaces, and removes soap scum, body oils and greases, bath oils, soap, and shampoo oils.

    On top of regular deep cleaning, you can avoid scum buildup by removing excess water after every shower. Use a rubber squeegee or microfiber towel to get rid of remaining water spots and leave the shower looking sparkling clean.
