If you’re battling stubborn mold stains, RMR-86 could be your go-to solution for quickly cleaning a pristine space.


  • Powerful formula works rapidly, removing stains within minutes

2. RMR Tub & Tile Cleaner

Your mold and mildew troubles in the bathroom could match those of RMR Tub & Tile Cleaner, offering a quick and potent solution.


  • Effectively removes mold and mildew stains without the need for harsh scrubbing
  • Safe for use on tiles and grout without causing discoloration
  • Pleasant modern orchard scent after use


  • It may require multiple applications for deeply set-in stains
  • The powerful formula means adequate ventilation is necessary during use
  • Higher price point compared to some other mold stain removal products

Upon first use, the RMR Tub & Tile Cleaner’s foam quickly adheres to bathroom surfaces, making application a breeze. The powerful formula works immediately; in most cases, significant results are visible within seconds. You’re left with less elbow grease to exert and a hint of freshness from its modern orchard scent.

This product doesn’t contain bleach, so safety is not a major concern. For best results, follow the instructions closely. It gently but effectively lifts mold and mildew from grout and tiles—and it’s made to cater especially to these tough bathroom contenders.

It’s refreshing to find that the RMR Tub & Tile Cleaner is manufactured in the USA, instilling confidence in its production and the quality of ingredients. However, when tackling some stubborn mold patches, patience is key. While the first application makes a significant difference, a second round might be needed, which means a bit more product is used over time.

Remember to keep the room well-ventilated when spraying this industrious foam, as the powerful formula is potent. While there’s an upfront investment, considering this isn’t the cheapest option on the market, the time you save not scrubbing and the efficacy of this product could very well justify the cost.

3. Tilex Mold & Mildew Remover

Tilex Mold & Mildew Remover is a robust cleaner that easily tackles mold in your shower, requiring minimal effort.


  • Effortlessly eliminates mold and mildew
  • Requires no scrubbing for most stains
  • Manufactured in the USA, ensuring quality


  • The odor can be overpowering
  • It should be used cautiously due to strong fumes
  • It may not be suitable for all types of surfaces

Reaching for the Tilex Mold & Mildew Remover after my last shower cleanup felt like a natural choice. Applying it was a breeze; spray and wait for it to do its magic. The mildew stains that once dotted the grout lines were visibly disappearing without any vigorous scrubbing.

In your shower, you’ll notice how this spray clings to vertical surfaces, ensuring the product stays where you need it the most. A few minutes is all it takes for the cleaner to penetrate, dissolve, and help lift away mold and its odors, making the entire process virtually hands-off.

It’s also wise to remember that while the Tilex Mold & Mildew Remover is potent, its powerful scent means adequate ventilation is necessary. Make sure to open a window or use an exhaust fan. Also, checking compatibility with your shower materials can prevent any unwanted damage from its use.

4. Wet & Forget Outdoor Cleaner

If you’re tired of the relentless scrubbing and seeking an effortless solution to outdoor mold, Wet & Forget is your go-to product.


  • Requires no scrubbing or rinsing, saving you time and effort.
  • It is non-acidic and contains no bleach, making it safe for various surfaces.
  • Long-lasting effects can keep surfaces clean for up to a year.


  • Results aren’t immediate; patience is necessary, especially with stubborn stains.
  • The weather-dependent application requires dry conditions and no rain forecasted within 4-5 hours.
  • Heavy and porous surfaces might require more product for coverage.

Using Wet & Forget, it’s clear this product lives up to its name. After a simple mix and a single thorough application with my garden sprayer, I could leave the area and let the product do the work. No harsh chemicals meant I didn’t need to worry about damaging my plants or the environment.

As days passed, the gradual transformation became evident. While initially skeptical about no immediate results, it was satisfying to see the green and black stains fade away without any more effort from my side. The convenience of not having to re-apply frequently is certainly a strong selling point.

However, it’s important to plan your application carefully. Ensuring the weather cooperates is crucial since rain can wash the product away before it can work. Those with heavy mold issues might take several months to notice significant changes, so manage your expectations accordingly.

Wet & Forget’s promise of simplicity and effectiveness holds, which makes it an excellent choice for anyone looking to tackle mold without turning it into a weekend project.

5. Zep Shower Cleaner

As someone who’s tackled stubborn mold, Zep Shower Cleaner is a robust choice thanks to its no-scrub, professional-grade formula that simplifies your cleaning routine.


  • Effortlessly dissolves grime and buildup without the need for scrubbing
  • Effective against various stains, including those from hard water and rust
  • It is pleasant to use with its spray bottle design


  • The strong scent may be overpowering to some after application
  • It can cause etching on metal fixtures if left on for too long
  • It may require heavy scrubbing for severe grout stains despite claims

Spraying Zep Shower Cleaner liberally across the affected areas, it’s noticeable how quickly it begins to penetrate the mold and soap scum. Even those tough-to-clean spots on the shower door seem less daunting. Minimal effort is needed as the spray starts working on contact, indicating the power of the professional-grade formula.

The ease of use is remarkable. The spray bottle allows for a fine mist that coats the tiles evenly, ensuring a comprehensive clean. Time is saved, not spent on tiresome scrubbing—rather, a simple wipe-down post-application does the job. The results are immediately visible: the tiles sparkle, and the area smells fresher, though the cleaner’s strong odor may necessitate good ventilation.

While the cleaner is fantastic for routine maintenance, it met its match with grout stains that wouldn’t budge. It took a bit more elbow grease than anticipated in those scenarios. Also, caution is advised regarding chrome and stainless-steel fixtures; they can tarnish if cleaner contact lingers. Despite these points, the Zep Shower Cleaner packs a punch, commendable for the daily battle against bathroom mold and soap scum.
