The Jelmar CLR PRO CL4PROEA Calcium, Lime, and Rust Remover is a strong contender for tackling hard water deposits in your shower. Its cleaning power is robust, effectively dissolving calcium, lime, and rust buildup across a variety of surfaces including glass, tile, sinks, tubs, and toilets. This makes it versatile and suitable for multiple cleaning needs around the home.

The ingredients are alcohol-free and it's safe to use on all plumbing types such as copper and PVC, which adds to its convenience and safety profile. However, it is not mildew-resistant, which means it might not be the best option if you're dealing with mold or mildew issues alongside hard water deposits. The lime scent is refreshing to some, but it might not appeal to everyone, depending on personal preference.

While the liquid formula is easy to apply, some might find it less convenient than sprays or gels that cling longer to surfaces. Importantly, the product is designed to leave surfaces residue-free, which is a significant plus for maintaining a clean and shiny finish.

It is a reliable choice for those specifically looking to combat calcium, lime, and rust stains in their bathrooms.

One of its strong points is that it is biodegradable, meaning it’s a more environmentally friendly option compared to some other cleaners. The mint scent is a pleasant touch, differentiating it from the harsh chemical smells of many cleaning products. The cream form makes it easy to apply and control, reducing the chance of spreading the product where it's not needed.

However, being an abrasive cleaner, it may require some elbow grease and could potentially scratch delicate surfaces if not used carefully. Additionally, while it’s clearly effective for bathroom use, the product's specific uses are somewhat limited, as it's not as broadly applicable for cleaning other household areas. It leaves a relatively minimal residue, but users might need to rinse thoroughly to ensure no leftover product. The single pack size of 20.3 ounces may not last long for larger households or extensive cleaning projects. It’s a strong choice for those specifically looking to clean hard water stains in their bathrooms, but it may not be the most versatile cleaner for all household needs.
