6 Best Grout Whiteners 2025 in the United States

The Clean-eez Grout Cleaner 2 Pack stands out for its professional strength, making it highly effective at removing years of grime and restoring your grout’s original shine. The inclusion of a 2-in-1 cleaning solution means you can clean both tile and grout with one product, saving time and effort. A notable advantage is the innovative stand-up grout brush, which simplifies cleaning in tight spots and on vertical surfaces like shower walls.

This brush, however, may not suit all situations like sealed grout or natural stone and might require multiple applications for heavily stained areas. The cleaner’s ease of application is a plus, thanks to the easy-control flip-top cap, but drying time is not specified, which could be a consideration for some users. In terms of durability, the product can renew grout without needing costly replacements, although using it on sealed or extremely dirty grout might lessen its effectiveness.

The 32 oz. bottles should cover a moderate area, but larger projects might need more product. Available in liquid form, the cleaner has a pleasant scent, making the cleaning process more bearable. The natural material feature implies it is safer to use, but always check for compatibility with your surfaces. The Clean-eez Grout Cleaner is a robust option for regular grout maintenance and deep cleaning, especially if you prioritize ease of use and a pleasant cleaning experience.

The Grout Pen White Tile Grout Paint Marker is a convenient solution for refreshing the look of your grout without intensive scrubbing. Its main strength lies in its ease of application; the pen format makes it user-friendly, perfect for tackling small DIY projects in areas like bathrooms and kitchens. The ink is long-lasting, capable of covering up to 150 feet of thin grout lines, making it efficient for both small and large projects. Another significant advantage is its advanced non-toxic, water-based formula, which ensures safety for users and the environment.

This product is intended for unsealed grout only, as it may not bond properly with sealed surfaces. Testing grout absorption with water beforehand is recommended. While the pen promises an accurate color match, the cap color may not precisely represent the final result, calling for a preliminary test area. Users should also be cautious with the cotton tip, which can wear down if pressed too hard, though replacement tips are available. The pen requires priming before use, which involves pumping the dry tip several times to activate. Due to its water-based nature, the drying time should be relatively quick. The pen’s compact dimensions and lightweight make it easy to handle, though proper storage is advised to avoid the tip falling out when shaken.

In summary, it excels in simplicity and performance, and users must follow instructions carefully to achieve the best results.

The Grout Pen White Tile Paint Marker by Rainbow Chalk Markers Ltd is a convenient solution for refreshing the look of grout without extensive scrubbing. The pen's narrow 5mm tip and water-based, non-toxic formula make it easy to apply, especially in tight spaces. It claims to cover up to 150 feet of thin 2mm grout, which is suitable for small to medium DIY projects.

The ink is waterproof and designed to last, although the cotton tip may wear down with heavy pressure, requiring replacement. The pen's simple activation process involves gently pumping the tip until it's saturated, but it should be done carefully to avoid damaging the tip. It's ideal for use in various areas of the home, such as bathrooms and kitchens, but it is crucial to test the grout first if it has been recently sealed, as the pen may not bond well with sealed grout.

Additionally, the color accuracy may vary slightly from the cap, so it's advisable to test a small area beforehand. The pen, which is environmentally friendly due to its water-based and non-toxic composition, is specifically designed for unsealed grout, limiting its usage for certain applications. Users looking for a quick and mess-free method to brighten grout will benefit from this product, though it may require some patience and care during application.
