What to Consider When Choosing the Best Bathtub Cleaner

Browsing the cleaning product aisle at the grocery store can quickly become an overwhelming experience: After only a few minutes, all the options begin to look alike. The following list is the result of research into the various kinds of cleaners to help consumers find the best bathtub cleaner for their bathroom. Consider these factors before buying a cleaner.

Bathtub Type

Bathtubs are manufactured from various products, including porcelain, acrylic, fiberglass, cast iron, and stone resin. Each of these surfaces is susceptible to scratches, so take that into consideration when choosing a bathtub cleaner. Most bathtub cleaners include the product’s tub type compatibility on the label. Also consider the various accessories, like bathroom caddies, in the tub area and the type of cleaning product recommended for them as well. Choosing the right cleaning tools not only helps with efficiency but also can minimize damage to the tub’s surface.


When choosing the best bathtub cleaner, also consider the type of cleaning project. Looking for a daily spray to keep the already-clean bathtub fresh and mildew-free? Or is the tub a little older and needs some extra TLC after a season of neglect? While multipurpose cleaners may tackle most needs, cleaners are formulated specifically to address the more intensive issues, such as hard water stains, black mold, and clogged drains.


Bathtub cleaners come in a variety of forms:

  • Liquid cleaners are, as the name suggests, suspended in a liquid. Less abrasive than powder cleaners, some liquid cleaners come in concentrated forms and require mixing with water before use.
  • Powder cleaners, which contain particles with abrasive properties to aid in scrubbing, can dissolve various oils, films, and stains.
  • Gel cleaners offer a splash-free alternative to liquid cleaners, so the cleaner lands exactly where it’s needed. Moreover, gel cleaners cling to the surface for longer penetration.
  • Foam cleaners, which generally come in the form of a spray, either aerosol or a pump, can cover a large surface area.
  • Scouring pads, which are often made from steel wool, sometimes contain a cleaning agent that aids in scrubbing and polishing.

Hard Water vs. Soft Water

The levels of calcium and magnesium in water determine its hardness. When these minerals are high, the water is considered hard. Signs of hard water include low water pressure, mineral stains on surfaces and clothing, and water spots on dishes after they’ve run through the dishwasher. Signs of soft (natural) water are a strong soap lather and strong water pressure. Hard water can leave stains on bathtubs that are difficult to remove, but products are made specifically to address this type of stain.

Organic vs. Chemical

Commercial cleaning products comprise chemicals that disinfect and deodorize, but many of these products contain harsh chemicals with warning labels to avoid contact with skin and eyes and use in well-ventilated areas. These chemicals often are labeled as combustible and corrosive. When rinsed down the drains into the water supply, they pose a threat to the environment. Organic cleaning products, on the other hand, are nontoxic and environmentally friendly, and they often are equally as effective as chemical cleaning agents.


When using cleaning products, more isn’t better. In some cases, high concentrations of cleaning chemicals can cause damage to the surfaces being cleaned and cause respiratory issues. Some cleaning products are available in a concentrate, which means they must be mixed with water.


While many cleaning solutions on the market are multipurpose—suitable for cleaning not only the bathroom, but also the kitchen or even the car—some people still prefer a product dedicated to one particular area, such as the bathtub.

Also, consider a product’s abrasive or non-abrasive qualities. Abrasive cleaners help reduce the amount of scrubbing required to clean a surface, but the abrasive particles may damage the surface with scratches and even remove the surface’s coating. Non-abrasive cleaners are good options for large areas that don’t require excessive scrubbing, such as a floor or countertop.

FAQs About Bathtub Cleaners

Don’t dread cleaning the bathtub! Instead, learn the tricks and tools to keep cleaning the tub a breeze.

Q. Which is the strongest cleaner for bathtubs?

Abrasive, acidic cleaners are the strongest when disinfecting and removing stains. The abrasive particles break down buildup, while an acidic pH melts away the deposits. But beware—the stronger the cleaner, the more likely it is to damage your tub’s surface if not used properly.

Q. Are bathtub cleaners toxic?

Most chemicals are toxic to some degree, and some bathroom cleaners with chemicals can become dangerous when mixed together, especially combinations like bleach and ammonia, which can cause toxic fumes and burn your skin. Adequate ventilation and gloves are recommended while using cleaning products.

Q. How do you deep clean a bathtub?

Deep cleaning a bathtub doesn’t have to be hard. If necessary, scrape the buildup with a tub brush before applying the cleaning solution.

Q. What’s the safest bathtub cleaner?

All-natural cleaning products are the safest because they’re free from toxic chemicals and irritants. A product like Better Life Natural Tub and Tile Cleaner can work wonders on the toughest bathroom jobs but remain safe to use.

Q. Can you use a toilet bowl cleaner on a bathtub?

When in a pinch, yes, you can use toilet bowl cleaner on porcelain bathtub surfaces. However, experts recommend diluting the cleaner with water before use. A toilet bowl cleaner that includes lactic acid rather than hydrochloric acid is less likely to cause damage to the tub’s surface.
