10 Best Fiberglass Tub Cleaners 2025 in the United States

Wet & Forget Shower Cleaner is designed for those looking to maintain a clean and fresh bathroom without the hassle of scrubbing. Its primary strength lies in its cleaning power, effectively removing soap scum, grime, and body oils from various surfaces, including fiberglass, without requiring physical scrubbing. This can save users considerable time and effort in their cleaning routine.

One of the standout features is its safety for fiberglass and other common bathroom materials such as porcelain and tile, making it a versatile choice. Additionally, the cleaner boasts a pleasant vanilla scent, which can make the cleaning experience more enjoyable compared to traditional harsh-smelling cleaners.

In terms of ease of use, the product is straightforward—simply spray it on, let it sit for 8-12 hours, and rinse. This weekly application can keep surfaces clean with minimal effort. Users do need to be cautious with heavy buildups, as it may require daily applications until the surfaces are fully clean. While the cleaner is effective for regular maintenance, it might not be strong enough to tackle very stubborn stains or heavy hard water buildup without some pre-cleaning. It's also important to note that it is not suitable for natural marble, so users must check their surfaces before applying.

Kaboom Foamtastic Bathroom Cleaner is designed to tackle tough bathroom grime with its blue foam that activates OxiClean stain fighters, effectively breaking down soap scum, hard water stains, and other common residues like calcium and grease. Its foam form makes it easy to apply, and you can tell when it’s time to wipe by watching the foam change from blue to white. It has a fresh scent that is pleasant and avoids harsh fumes, which many users will appreciate.

Although it’s primarily targeted for tile, it is generally safe for fiberglass tubs as it doesn’t contain strong acids or abrasives that could damage the surface. This makes it a suitable choice for those looking to keep their fiberglass tubs clean without risking harm. One thing to note is that, like many aerosol products, it may not be the most environmentally friendly option due to its packaging and propellants. If ease of use and effective stain removal with a nice scent are your priorities, Kaboom Foamtastic is a solid option to consider for maintaining fiberglass tubs.

Using it is simple — just spray and wipe — making it convenient even for those who prefer a no-fuss approach. CLR Brilliant Bath is a strong option for general bathroom cleaning needs, particularly if you seek an easy-to-use product with a fresh scent. If specific concerns like fiberglass tub safety or environmental impact are important to you, it may be wise to verify those details or explore alternatives that specify these aspects.
