How to Clean Onyx Shower – 3 Simple Solutions

For your convenience, this post has links to Amazon.
Although onyx showers have an easy to clean texture, cleaning it is not everyone’s expertise. If you want to know how to clean onyx shower and want to put in some effort, you can also do it yourself.

Remember that cleaning the onyx shower is a bit different than cleaning other parts of the bathtub. Onyx is a stone material and cannot be cleaned the same way as other tubs because it is a material that is sensitive to abrasive cleaners. That means you couldn’t simply start scrubbing with the same stuff that was used for porcelain.

Tip: Use a cleaner made for natural stone

You can use a cleaner that’s made to be used on natural stones like onyx. Check to see if your current cleaner has abrasive beads, like those you’d use on textured fiberglass tubs, or did not specify that it’s for use on natural stone. Then you’d want to skip them for the onyx in the bathroom.

If you want to do it the right way, check out this do-it-yourself guide that includes tips and steps you can take when cleaning your onyx shower.

How to Clean Onyx Shower

How to Clean Onyx Shower

Method 1: Water and Vinegar

Step 1: Prep the Shower

Remove items like shower caps, combs, shampoo, hand soaps, and razors from the shower area because they are going to get in the way of wiping the walls and floor. You should consider running hot water through the whole shower.

Simply run hot water and then wait a few minutes. The wetness will cause grime and stains to loosen, which will make it easier for you to remove them from the floor and walls of the shower.

Step 2: Mix Water & Vinegar

Low concentration white vinegar can be used on onyx. Create a 50-50 solution by mixing equal parts vinegar and water. This will kill mildew while dissolving soap scum at the same time.

Step 3: Wipe the Shower Clean

Dip a soft cloth in this homemade solution and wipe down the shower walls and floor.

You can also pour the water-vinegar mixture into a spray bottle if it works better for you. Spray the solution on the onyx surface, leave it for about 30 minutes, and wipe in circular motions.

Step 4: Repeat if Needed

Repeat the process if necessary. For stubborn stains, you will need to wait 15 minutes after applying the solution to enhance its effectiveness. Add a soft cleaner to make it more effective.

Tip: Clean your shower regularly to prevent hard water stains from developing over time. Otherwise, you’ll have to put more time and effort into removing these deposits and unsightly marks.

Step 5: Rinse Thoroughly

After getting out stains and dirt, rinse the surface with water. In addition to the walls or floor, your shower door should also be washed away. Don’t overlook it!

Method 2: Clean Onyx Shower with Soft Cleaning Soap or Soap Scum Cleaner

Step 1: Prep Your Shower Area

Remove personal products and accessories from the onyx shower. Check the bottom of bottles for mold to identify those that have to be disinfected. Do you have a shower curtain? Before you start to clean onyx, it should be removed too.

Step 2: Make Steam in Your Shower

Once you’ve prepared the shower area, generate steam by turning on the shower. It goes without saying that you need to use a hot water setting. This will make it easy to remove grime and soap scum from the floor and walls.

Step 3: Apply the Cleaning Solution

A PH-neutral cleaning product like soft cleaning soap is a safe bet. It’s great for cleaning onyx. Unlike abrasive cleaners, cleaning soap will neither harm the stone nor make it lose shine. Simply apply it to the shower and wait a few minutes before rinsing it off.

For the hard-to-remove buildup of soap scum, use a cleaning sponge and soap scum cleaner. Make this effective solution by mixing water with baking soda, powdered milk, and liquid castile soap. Allow a paste to sit for about 10 minutes.

Step 4: Wipe Down and Rinse

Use a non-erosive cloth when wiping down your shower. Soft tissue and microfiber towels are also recommended. Avoid brushes and rough scrubs. Rather than spraying the solution directly on the surface, apply it to the cloth or towel first.

Rinse it off to remove the soap. Use warm water to get the best results. Lastly, blot spills with a soft, clean towel to prevent any marks from forming. That’s it!

Method 3: Clean Onyx Shower with Homemade Onyx Stain Remover

Step 1: Steam the Entire Shower

Just like with the previous methods, prepare your shower first. Afterward, steam your bathroom to smooth the process. The steam can do a good job of loosening hard water stains. Open up the door and window(s) while doing this to ventilate your bath.

Step 2: Make Onyx Cleaner

Homemade onyx stain remover that consists of baking soda and Epsom salt is a good alternative to commercial soaps. It is easy to make and can quickly lift stains without causing any damage to onyx.

To make this stain-fighting natural formula, combine 1 tbsp. of baking soda and 1 tbsp. of Epsom salt with a cup of water. Place all the ingredients into a small kitchen bowl and stir them well to form a paste. You can also add 3 or 4 drops of essential oil.

Step 3: Clean the Walls and Shower Hardware

Start by cleaning the walls of your onyx shower. Apply your stain remover to either a cleaning cloth or sponge. It’s better than applying the paste/cleaner directly to the stains. Make sure the entire surface is covered.

Allow it to sit for 15-20 minutes. Then wipe the wall tiles clean using circular motions. Once you’ve finished with the wall, switch to the shower hardware. It involves cleaning the knobs and showerhead with a cloth. You may also use a soft-bristled brush or sponge.

Step 4: Clean the Floor

Now it is time to deal with the shower floor. Begin on the side that is farthest from the entrance and keep working your way toward the door. Use circular motions and take special care of the grout between the onyx tiles. Mildew and mold tend to accumulate in that area.

Use a brush with soft bristles to avoid damage. For more thorough cleaning, employ a disposable toothbrush. It is excellent for areas that are hard to reach. A steam mop is suitable for spacious floors that need to be cleaned and sanitized.

Step 5: Rinse the Shower with Warm Water

Let the stain remover sit for several minutes before moving to this last step. After turning your shower on hot or warm water, rinse it off and pat the onyx tiles dry with a clean cloth. Never use a scrub brush or scouring pads.

Pay attention to the showerhead beside the walls, door, and floor. The last thing you want is to leave a residue when cleaning your onyx shower. It will make it less attractive and dull. To avoid this, make sure the cleaning solution is rinsed thoroughly.
