Mold can grow in a variety of places in your house, including the shower. You should also learn to remove mold from a pebble shower floor and be on the lookout for signs of mold growth.

Keeping your environment mold-free is just as important as keeping your body clean. A clean shower room is a great example of how to maintain a healthy home environment for your family.

A pebble shower floor not only adds a dash of style to your bathroom, but it also decreases the chance of tripping and falls. While it’s a common misconception that pebble shower floors are slick and dangerous to walk on while wet, the opposite is true.

Pebble shower floors are becoming a popular trend in interior design because they are both attractive and comfortable. If you’re a homeowner seeking for shower floor ideas, consider using pebbles.

What to Consider before Cleaning

Depending on the type of installation, it’s important to know what to do before you begin cleaning. Pebble stones can be put in two distinct ways:

  • Epoxy
  • Sealant/grout

For epoxy, there is no need for a severe cleaning process, but for other materials, such as wood, there is. Pressure washer and light detergent are all that’s needed. Alternatively, you can easily clean the pebble stones with hot/warm water mixed with soap.

Because there is so much grout exposed that traps dirt, grease, and soap scum, a seal coat or sealer is needed to protect the surface. The cleaning process will be more extensive than the previous epoxy-based installation.

Because porous pebble stones are utilized in grout sealing, cleaning will be more thorough.

Baking soda and vinegar paste or an unique clay-based poultice may be needed to get rid of stains on some types of pebble flooring.

Type of Cleaning

Determine the type of cleaning you wish to perform in the next step. There are three distinct kinds of people:

Mild Washing

You only have to use mild detergents to clean the shower floor. To prevent strong chemicals from corroding the surface of the stones, this is best used with little pebble stones.

It’s easier to clean with mild detergents because they have a more alkaline basis than acidic ones.

Bleach and other harsh household cleansers will scratch the pebble stones’ surface, degrading their beauty over time.

There are other locally produced pebble stones that can be influenced by this, such as travertino, limestone, marble, and even granite.

Steam Cleaning

Handheld steamers are used to clean and loosen grime by changing temperatures, as you might expect. Just like using hot water, but in steam form.

The steamer is held three to six inches above the pebble stone flooring surface, where dirt and soap scum are steamed until loose, and then water is used to rinse the rest out easily.

Stone Cleaners

Finally, you can use industrial hydrochloric acid and ph neutral or basic proprietary cleaners to wipe out the floor in a professional manner.

Allow the cleaning mixture to sit for a while, just as you would with paste, to release dirt and grime from the flooring gap. Step by step instructions can be found in the following section.

4 Effective Ways In Cleaning Mold Off Pebble Shower Floor

Shower floors are ideal for the installation of pebbles, which are available in a wide range of shapes, sizes, and colors. Since pebbles come in a variety of forms and sizes, gaps form between them.

Mold loves these cracks and crevices. For this reason, learning how to remove mold from pebble shower floors is a good thing for homeowners to learn.

1. Scrubbing

This method demands some physical exertion, but it saves money in the long run. Using your old soft bristle toothbrush to clean it could actually save you money.

Soft bristle brushes can be used to completely clean the nooks and crannies that are difficult to get to, preventing scratches. After that, use warm water to thoroughly remove the mold off the surface.

2. Bleaching

Bleaching pebble shower floors is one of the best ways to get rid of mold. Spray the area with a mixture of bleach and water and leave it there for 10 to 20 minutes before rinsing it off.

After that, use warm water to wash it off and a mop to dry the shower floor. Bleach cleaners are currently available in a wide range of kinds, many of which have undergone significant innovation to become multipurpose.

If the pebble shower floor is made of granite, marble, or limestone, using such a strong bleach can damage the surface. Make sure to read product reviews before deciding on bleach cleaning.

3. Baking soda and vinegar solution

Both of these items can be found in your pantry or kitchen cupboards, or they can be purchased cheaply from a convenience store. You can check out this post on what causes mold in kitchen cabinets if you ever find yourself struggling with mold in your kitchen.

With the help of baking soda and vinegar as the acid and base, you can get rid of stains, germs and mold. It also has natural cleansing and deodorizing characteristics that work well with pebble shower floors.

The only caveat to this method is that you must use white distilled vinegar. Vinegar with coloring properties might leave a stain when used to clean, so you must use vinegar that does not have this property.

4. Hydrogen peroxide

Hydrogen peroxide is one of the best ways to remove mold from pebble shower floors. Cleaner and disinfection all in one, you can pick this up at any drugstore without much trouble.

Mix one cup of hydrogen peroxide with two cups of water in a spray bottle before using it on the pebble shower floor. It’s easy to treat the damaged areas: just spray the solution on and then rinse with warm water.

What Mold Looks Like In Pebble Shower Floor

Mold growth in your shower is most likely as a result of the constant presence of water moisture. Specifically, pebble shower floors are more susceptible to mold due to their lack of drainage area and crevices between pebbles.

Because mold and pebble shower floors sometimes have the same color, it can be difficult to determine what type of mold is present. Moss, for example, has a green mold-like appearance.

With a variety of hues to choose from, mold from a pebble shower floor is visible. As a result, all you need is a clear view of mold to get rid of it.

How to Clean Pebble Stone Shower Floor - 5 Simple Tips

Step by Step Guide to Cleaning the Shower Floor

Let’s get started now that you’ve figured out what you need for the cleaning process.

Step 1: Collect Water and Add a Disinfectant

Bring a quart of water to a boil, then add a few drops of your preferred mild detergent. Vinegar or a moderate household cleaning product might be used in its place. To make a lathering solution, gently combine the two ingredients in the bottle.

The first step in deep cleaning is to apply a paste of your cleaning agents and let it sit for a while to loosen the grime. Bring this step-by-step guide with you when you arrive.

Step 2: Begin Washing

Pour the water and soap mixture over the entire floor, starting from the corners and working your way outward. Each and every crack and crevice on the bathroom floor should be thoroughly cleaned with the antibacterial detergent. The black patches and holes in pebblestone floors that collect dirt, filth, and soap residue are well-known.

Alternatively, you can move on to the following stage and leave the solution sitting for a while. Pour some vinegar into the sink and let it soak for a few minutes before you begin scrubbing.

Step 3: Gently Begin Scrubbing

Gently scrape the stones and grout with a nylon-bristle scrub brush to remove the dirt. Back and forth or circular motions can be used to navigate around the rocks and corners.

Dirt, body oils, soap scum, molds, and mildew should all be easily removed with a simple brushing.

After brushing, rinse your teeth with warm water and re-brush any areas that aren’t completely clean.

Step 4: Rinse Out the Soap

Soap and filth from the bathroom can be washed away by dumping water all over it after cleaning it. As an alternative, you can open the shower door and allow the water and soap to wash away the dirt and grime. Use hot or cold water, as you choose.

Step 5: Finish Up

Mold and mildew can thrive in a moist environment, therefore it’s best to dry out the floor so that it doesn’t become a breeding ground for the two.

Call an expert cleaner if you’re not satisfied with the outcomes and the stubborn stains remain. Hydrochloric acid and hydrogen chloride would be used to remove the dirt thoroughly in this scenario. To be clear, these are only extreme situations.

Tips to keep Pebble Floor Clean

Because cleaning the shower floor can be exhausting, we’ve compiled a list of suggestions to make it easier.

  • Make sure to dry the floor after you take a shower to prevent the growth of mold and mildew. Getting as near as possible is more important than drying it fully. The shower curtain or door should be cleaned in the same manner.
  • Vinegar is the greatest way to erase stains caused by hard water. To remove hard-water deposits, spritz the bathroom with a vinegar/water solution and allow it to sit for 30 minutes. It’s all cleaned up when you’re done rinsing it off. Stains caused by hard water increase the collection of further dirt spots. As a result, take care of any spills right away.
  • The pebble stains should be handled with care. It’s easy to develop etch marks on natural stone floors if you over-scrub them. Using abrasive cleaners or scraping the stone too hard can damage the sealant, which is supposed to protect it.
  • Clean and dry the bathroom floor with soft cleansers, sponges, or clothes to prevent leaving any hard patches. You can extend the life of the floor by doing this.
  • To avoid damaging your pebble stone shower floor, avoid using a vacuum cleaner. The sealant or stones may be damaged or harmed as a result. This doesn’t do much damage to your flooring, because the sealant keeps the holes in the pebble stones from filling up with dirt and water.
  • Stone floors should be cleaned and polished on a regular basis to keep its natural beauty and authenticity. After each bath, use a soft towel or washcloth to swiftly and gently clean the floor to remove any buildup. Keep the bathroom clean by avoiding the use of any abrasive liquids there. It is also discouraged to use bleaching products on a regular basis.
  • In addition to proper ventilation, stone flooring must also be kept clean and fresh at all times. In order to keep mold and mildew at bay, it’s important to keep the air moving. Ventilate the bathroom after each shower to allow for free air movement. When working with strong chemicals, it’s a good idea to use ventilation as well. The less oxide you can smell, the better it is.

In order to keep pebble stone shower flooring clean, it is essential to clean the bathroom on a regular basis.

Clean, dry, and aerate the floor as part of a regular cleaning schedule. Wash the shower door and curtains once a week to prevent the growth of mold and mildew. A clean and beautiful bathroom floor can be achieved by following these guidelines.

How To Care For Stone Shower Tiles

In order to properly care for stone surfaces, it is necessary to understand that stone shower tiles are continually exposed to moisture. You can take specific precautions to protect the stone while preserving its beauty. Stone shower tiles can be cared maintained in a number of ways.

1. Keep The Tiles Clean

To keep your marble, granite, quartz, or other stone tiles looking their best, you’ll need to clean them on a regular basis. Cleaning the shower tiles with a stone-safe cleaner on a weekly basis is the best way to keep them clean and sanitary. Acidic and ammonia-based products should be avoided since they can damage natural stone. Using Rock Doctor’s Granite and Quartz Cleaner, you can safely clean all of your natural stone surfaces, including the bothersome shower tiles.

As a preventative measure, you can rinse the shower after each use to ensure that no shampoo or soap residue remains on the tiles.

2. Dry The Tiles After Showering

Mildew and mold development can occur if natural stone is left moist all the time. You can use a squeegee or a microfiber cloth to completely dry the tiles after each shower. Allowing the tiles to dry faster on their own is made easier by using a squeegee. Using a microfiber cloth is a great way to get your tiles completely dry. Excess moisture can be removed from the bathroom to help lower the humidity.

3. Pay Attention To Your Grout

Even while grout may appear insignificant in comparison to your stunning stone tiles, ignoring it will leave you with a dingy shower, no matter how gorgeous your tiles are. You can use a soft nylon brush or a toothbrush to carefully loosen the filth from your grout while using a stone-safe grout cleaner like Rock Doctor’s Tile and Grout Cleaner.

4. Get Rid Of Mold And Mildew Quickly

Mold and mildew are unsightly, but they also pose a health risk to you and your family. Mold and mildew forming on your shower tiles can be safely removed with a bleach-and-water solution. Avoid injuring the stone by using a non-scratch sponge or pad to carefully remove the mold and mildew.

It is feasible to prevent mold by drying the stone tiles between showers as thoroughly as possible using the methods in section two.

5. Seal Stone Tiles Regularly

It doesn’t matter where you have natural stone in your home; it must be sealed to protect it against moisture and grime. Shower tiles are particularly vulnerable to water damage. Sealing these tiles on a regular basis is necessary because of this. If you seal stone every six to 12 months, you may want to check the sealer on shower tiles every four to six months to see how it’s holding up. Sealing the stone more frequently may be necessary in some circumstances. Sealer can be prematurely removed from tile if the wrong cleansers are used.
