When soap combines with hard water, it can leave a filmy, whitish residue in your tub, shower, and sink known as soap scum. It’s especially noticeable on metal fixtures, tile, and grout. This buildup is hard to remove and needs daily and weekly removal.
In most cases, nontoxic spray will work without damaging surfaces. For older, deeper stains and stubborn scum, you may need to combine a concentrated formula with a scrub brush and some elbow grease. That said, read on for the best soap scum removers and shopping considerations to address your scum in minimal time.

Before You Buy Soap Scum Remover
An ounce of prevention, as they say, is worth a pound of cure. If you have hard water, make sure you’re removing water spots and mineral deposits daily or weekly before they have a chance to build up into scaly scum. Those with hard water might also want to consider using a shower head filter that lowers the level of minerality in the water. Another trick is to buy a good soap dispenser so liquid soap isn’t dripping and causing stains and scales to form.
How We Chose the Best Soap Scum Removers

Best Scrubber
Mr. Clean MagicEraser Bath Cleaning Pads
This impressive bathroom cleaner is designed for reaching into surface grooves; cleaning grout; and removing tough, stuck-on stains and grime from the tub, shower, sink, toilet, floor, and walls. The four- or 10-pack of bathroom scrubbers is made out of a white Durafoam material that is filled with foaming cleansers to help loosen and remove soap scum, toothpaste, fingerprints, and grease.
However, the Magic Eraser shouldn’t be used to clean inside the toilet bowl because the toilet water can cause the bathroom scrubber to quickly lose its foaming cleansers. The bathroom cleaner activates with just a little water, releasing the cleansers while you apply abrasive force to the surface with the Durafoam scrubber. This also has the added benefit of creating a pleasant, fresh scent.
Product Specs
- Key ingredients: Melamine resin foam
- Form: Cleaning pad
- Multipurpose: Yes
Pros
- Comes with a pack of 4 or 10 flexible scrubber sponges
- Can remove soap scum, toothpaste, fingerprints, and grease
- Leaves behind a fresh lavender scent
Cons
- Not suitable for use in a toilet bowl

Or, DIY Your Own Soap Scum Remover
While many great commercially available soap scum cleaners are on the market, you can also create an effective, eco-friendly soap scum cleaner using common household ingredients.
Mix 1 cup of white vinegar and 1 cup of water in a spray bottle, warming the vinegar first to help it blend. Add a tablespoon of natural liquid soap, like castile, and 10 drops of tea tree essential oil for its antimicrobial properties.
Spray the solution generously onto the afflicted area and let it sit for about 15 minutes. This allows the vinegar to break down the soap scum, making it easier to wipe away. Then, scrub gently with a soft cloth or nonabrasive sponge. Be sure to rinse thoroughly afterward to avoid leaving any residue.
This formula is biodegradable, nontoxic, and friendly to both humans and the environment.

Our Verdict
When it comes to soap scum removal, products like Clorox Clean-Up All Purpose Cleaner With Bleach and Scrubbing Bubbles Mega Shower Foamer Disinfecting Spray are popular for their efficacy. However, these products fall short of our sustainability guidelines. Despite their popularity, we don’t recommend them in our top picks due to concerns about their environmental impact, harmful chemical ingredients, and potential health hazards.
What to Consider When Choosing a Soap Scum Remover
Even with the best cleaning efforts, scum happens. To cure your bathroom surfaces of this scourge, consider the following.
Surface Type
Bathrooms contain a mix of surface materials from metal fixtures to ceramic tiles to fiberglass, acrylic, or porcelain tubs. You don’t want to damage any of these materials in the process of cleaning them—but switching between cleaners every time you touch another surface isn’t necessarily a convenient solution. When shopping for soap scum removers, be sure to look for formulas that are compatible with a wide range of surface types.
Make sure the formula does not contain harsh abrasives, chlorine bleach, or strong acids, which can permanently cloud or scar anything from metal to glass. For mirrored and glass surfaces, you will likely want to purchase a separate specially formulated product, since these materials streak easily and require surfactants or solvents to provide that perfect shine.
Formula
Soap scum busters come in a wide range of formulas. For all but the most severe cases of buildup, you may opt for a plant-based, nontoxic solution rather than a product containing heavy artificial chemicals. Nontoxic solutions should not include chlorine bleach, ammonia, heavy fragrances, or phthalates.
Instead, they use mild abrasives (like salts or baking soda), less caustic acids (like lactic, citric, or gluconic), hydrogen peroxide, or other plant-based surfactants (ingredients that lift dirt and mineral buildup through chemistry).
The best soap scum remover may also be certified by the USDA and the EPA. You can also check out the Environmental Working Group (EWG)’s Guide to Healthy Cleaning for product toxicity and ratings. Nontoxic removers work on a diverse range of surfaces and are often just as effective as commercial chemical solutions for household use.
They are also safe for people with allergies and health issues as well as kids and pets. For use around drains and in toilets, look for septic-safe formulas, too. If you are sensitive to scent, many brands now offer scent-free alternatives as well as solutions containing essential oils rather than artificial fragrances.
Application Method
In addition to plant-based or nontoxic formulas, soap scum removers come in a range of different application types:
- Sprays are the simplest and easiest to use. Spray onto the affected area, wait a few minutes, and then rinse clean. For stubborn scum and water spots, you may also use a non-scratch scrub pad along with the spray to lift buildup from the surface.
- Creams and concentrates provide more bang for the buck and are also designed for professional-grade industrial-strength applications. These products may be applied directly to surfaces using a nonabrasive pad or diluted in a separate container according to product instructions.
- Cleaning pads should always be non-scratch so you don’t damage the surface. They are helpful for removing soap scum that sprays and even creams alone can’t erase. Combine your chosen spray or concentrated product with a cleaning pad only on hard surfaces, like tubs, tile, shower doors, and sinks, that can handle mild abrasion. In most cases, it’s also best to wear gloves while cleaning.
FAQs
There’s a little chemistry involved in soap scum creation and removal. Knowing the basics can help you choose the right remover to preserve and clean your bathroom surfaces effectively.
Q. How does soap scum build up?
Over time, minerals like calcium and magnesium, found in hard water, combine with soap and dirt to create a scaly film that coats bathroom surfaces, fixtures, laundry, and more.
Q. Does hard water cause soap scum?
Yes. Hard water contains minerals (calcium and magnesium) that chemically combine with soap to create scum and limescale.
Q. What is the best thing to use to remove soap scum?
A non-scratch sponge, along with a specially formulated cleaning product, is often the best method to remove tough soap scum. Apply the product as directed and buff gently. Rinse clean with water.
