The Best Grout Cleaners and Brushes of 2026, Tested and Reviewed

For a great multipurpose grout cleaner, we recommend this fast-acting spray from Black Diamond. It works on dirt, grease, grime, soap scum, food spills and stains, and it doesn't contain a bleaching agent, so it's safe to use on any color of grout and natural stones. You only have to let the cleaner sit for a couple of minutes before scrubbing and rinsing to achieve great results versus triple the time for some of the other cleaners we tested. Our tester saw significant brightening on her grout after using this spray. While this cleaner will be sufficient for most grouted surfaces, it's not ideal for heavy mold, mildew, calcium or water spots. It's great for quick cleans and regular maintenance, and it's easy to target a specific spot with the sprayer.

If you have old grout that you can barely tell was originally white, this is your cleaner pick. We tested this one on a decades-old tile floor and it literally made it look brand new. It brightened the white grout we tested it on more than any other cleaner we tried, and it's effective on mold and mildew. Since it's in gel form, it's easier to target than a spray, and you can use it on grout, tile, tubs, countertops, toilets and more. You just apply to the grout, rub and rinse. Since it contains bleach, this cleaner isn't recommended for colored grout, and be sure to wear gloves and avoid contact with clothing as it can discolor fabrics.

Most traditional cleaners are not recommended for use on natural stone like marble and unsealed granite as the chemicals they contain can etch natural stone. This spray from Granite Gold is formulated without acid or ammonia, so it's safe on natural stone and white and colored grout. While it's not as effective on tough stains and buildup as other cleaners on this list, it noticeably brightened our grout and worked better after sitting for 5-10 minutes. Plus, it’s biodegradable, non-toxic and food-safe, and it has a pleasant citrus scent.

If mold and mildew is your main concern, this spray cleaner can help keep the problem at bay. It kills 99.9 percent of bacteria and 99.9 percent of germs, including cold and flu viruses. Plus, it prevents the growth of mold and mildew for seven days on hard surfaces and destroys soap scum. It also has a pleasant citrus scent and can be used almost anywhere — counters, sinks, toilets, bathtubs, showers, tile, sealed granite, sealed marble, glazed tile, formica, corian and stainless steel.

Made of bamboo and recycled plastic, this grout brush from Full Circle is the perfect shape for getting in grout lines but is also large enough to be used on tile floors, counters or tubs so you don't have to use multiple brushes for different areas of your bathroom. Plus, it's comfortable to use and rests upright for faster drying.

This two-piece brush set from OXO includes two sturdy cleaning brushes with tough bristles. The small brush has a built-in wiper blade to remove dirt from drains and crevices. We love that it can get in grout lines as well as other awkward nooks and crannies like around faucets and drains. Our tester was initially concerned the brush was going to get soft and lose its shape, but it held up really well.

If you still want a smaller brush head to easily target grout lines but want to minimize the level of elbow grease you have to put in, let this electric scrubber from Rubbermaid do the hard work for you. Oscillating heads scrubs 60 times per second, interchangeable accessory brushes give you the right tool for the job and four AA batteries are included.

For something you can literally tackle the whole bathroom with, this four-piece drill brush kit is a great multipurpose pick. The different brush heads attach to a drill (not included) and can cover every spot in a bathroom. While the drill does all the hard work for you, it is good to note that the brush tends to splatter excess grime around the bathroom that usually requires a quick wipedown.

If you have a large floor to tackle, this affordable brush with an extendable, telescoping handle will help you cover a larger area in less time. The brush head nestles right into the grout crevices, removing built-up dirt with ease. We expected the bristles to fray after our vigorous scrubbing, but they looked as stiff as when we pulled it out of the box. Plus, it's slender and easy to store.
