10 Best Sandstone Cleaner 2025 in the United States

The Miracle Sealants TSC4GAL Tile & Stone Cleaner Concentrate is a versatile option suitable for both indoor and outdoor use, which is essential for maintaining sandstone surfaces. Its non-toxic formulation makes it safe for food areas and regular use, featuring no odor, which is a big plus for indoor applications.

The liquid form makes it easy to apply, and it promises to be residue-free, which means no streaks or unwanted marks will be left behind, enhancing the appearance of your sandstone. This product seems ideal for regular maintenance rather than deep cleaning of heavily stained sandstone.

Being from a reputable brand, Miracle Sealants, and made in the USA, adds to its reliability. Weighing 3 pounds and with dimensions of 4.25 x 7 x 11.5 inches, it is manageable to handle and store. If you are looking for a general-purpose sandstone cleaner that is safe and easy to use, this could be a good option.

The Wet & Forget Moss, Mold, Mildew, & Algae Stain Remover Multi-Surface Outdoor Cleaner Concentrate is a versatile cleaner for various outdoor hard surfaces. One of its main strengths is the 'wet it and forget it' application method, which requires no scrubbing or rinsing. This is particularly convenient for users looking for a low-effort cleaning solution. The product's formulation is bleach-free and non-acidic, making it safer for a variety of surfaces without causing damage or leaving harmful residues.

It’s suitable for both indoor and outdoor use and covers a wide range of surfaces, from driveways and patios to roofs and decks. This makes it highly versatile and a good choice for homeowners looking to clean multiple areas with a single product. The stain removal capability varies depending on the severity of the stains. While green stains can be cleaned up within 1-2 weeks, more stubborn black stains may take several months, and long-established stains could take up to 12 months to fully disappear.

This extended cleaning time might be a drawback for users looking for quicker results. Another limitation is the coverage, which ranges from 375 to 1,125 square feet. Heavily stained or more porous surfaces will require more product, potentially reducing coverage. Additionally, users need to be cautious about applying the cleaner near water bodies and should rinse plants before and after application to avoid damage. The product's ability to keep surfaces clean for up to a year or longer is a significant benefit, offering long-term maintenance with minimal effort.

The STONETECH Mold & Mildew Stain Remover is designed specifically for cleaning natural stone surfaces. It comes in a convenient 24-ounce spray bottle and is sold in a pack of two.

This makes it particularly suitable for both indoor and outdoor use on natural stone surfaces, ensuring the longevity and appearance of your stone fixtures.

The foaming action sprayer is a practical feature as it helps the cleaner cling to surfaces, preventing drips and making application easier and more efficient. This eco-friendly cleaner has a fresh, natural scent that won't leave behind harsh chemical odors, which is a significant advantage for indoor use. Additionally, it has a residue-free formula, meaning it won't leave any unwanted streaks or marks after cleaning.
