Best Soap Scum Remover


It’s a nasty combination. 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, but it can also affect tile and grout. Over time, this mineral buildup becomes increasingly hard to remove, which means you’ll want to stay ahead of the curve and find a soap scum solution that works for daily and weekly cleanups.

In most cases, a nontoxic spray will do the trick without damaging surfaces or requiring heavy chemicals. For older, deeper stains and stubborn scum, you may need to combine a concentrated formula with a scrub pad and some elbow grease. That said, the right product can address your scum situation in minimal time, restoring your bathroom’s shine and freshness.

What to Consider When Choosing the Best Soap Scum Remover

An ounce of prevention, as they say, is worth a pound of cure. So 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. Another trick is to buy a good soap dispenser so liquid soap isn’t dripping and causing stains and scales to form. However, even with the best 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. So 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 glass and mirrored 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.


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, 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 in lifting 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 About Soap Scum Removers

There’s a little chemistry involved in soap scum creation and removal. Knowing the basics can help you choose the right remover and preserve your bathroom surfaces over time.

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, 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.
