Grout is common in kitchens because tile is relatively easy to clean, it looks nice, and it can blend in with a variety of decors. However, your kitchen is a very busy area that sees a lot of traffic every day, and this can lead to unsightly grout stains that make your entire floor, wall, or backsplash look dingy and dirty. No matter how hard you scrub, it’s difficult to get it clean without using a specialized grout cleaner, scrub brush, and a little elbow grease.
There are hundreds of different grout cleaners available from different companies that all claim to do the same thing. Some work to lift out stubborn grout stains with minimal scrubbing on your part, and others require you to work at it until the stains come out. If you have a big kitchen, buying the wrong grout cleaner can mean you waste hours every few weeks scrubbing, and there are so many other things you could be doing. This is why I picked out 10 high-quality grout cleaners and included a short buyer’s guide you can use to narrow down the products until you get the best choice for your home.
Ideally, your grout would stay clean by itself with a little work from you. However, it’s the perfect area for dirt and grime to get trapped, and this can make your whole kitchen look dirty. A quality cleaner will strip the dirt and grim from the grout to make it look like new.

You can also easily apply it to shower-heads and faucets without a problem. However, this solution does take between six to eight hours to work, so it’s a good idea to apply it at night and let it sit overnight before scrubbing it away in the morning.

Grout Cleaner Buyer’s Guide
You want to get a good product when you start shopping for your grout cleaner, but there are so many options available that it can take time to narrow down your choices. There are several criteria you can look for when you start comparing products, and I’ve rounded up the most important aspects to consider below.
Why Use a Grout Cleaner
When you first install your tile in your kitchen, apartment, bathroom, laundry room, or out on your patio, it looks fresh and new. However, general use allows dirt and other contaminants like grease and mud to get trapped in your grout. Eventually, this will lead to discoloration, and it can cause your new tile floor or wall to look dirty and unkept. A grout cleaner will gently remove this buildup while restoring your grout to ensure that it doesn’t look grimy. You usually apply it, wait a few minutes, and then scrub it off before rinsing your floor.
Many people choose to go with darker grout to help hide the grimy look, but you should clean it routinely to help extend the length of your floor’s life.
How long can you go without using the area you want to use your cleaner on? If it’s something like a spare bathroom, you could potentially leave your cleaner to sit for hours without anyone disturbing it. However, your kitchen usually has a higher volume of traffic, so you need something that works quicker. Double-check and see how long your product recommends it sits on your grout for before you wash it off. This can range from a few minutes to eight hours.
These types of cleaners come in many different strengths. If you get a commercial-grade product, it’ll have a stronger formula than you’d use at your home. If you don’t get the right strength, you could find yourself refinishing your flooring because the cleaner accidentally stripped protective coatings, waxes, or other finishes off. You want to look and see which surfaces the product recommends and which it tells you to avoid because some won’t work well on ceramic or porcelain while others will.
Although tile and grout is very popular in the bathroom, you’ll find it in a lot of kitchens because it’s relatively easy to clean and maintain with the variety of stains and grease you introduce in the kitchen.
Generally speaking, a lot of the products on my list were on the cost-effective end of the spectrum. But, some require you to clean them two or three times, and this can take up a lot of product. You want to find something that will at least cover the square footage of your kitchen once, if not twice. This can vary widely from product to product, but concentrated solutions usually cover more area than diluted ones.
You want to be safe when you use your cleaner, especially if you have pets or kids running around that could accidentally get into it. If you get a fast-acting formula, you can use it while your kids are outside playing games. However, it’s generally a safer idea to get a non-toxic formula that is biodegradable. This way, it won’t hurt anyone if they get it on them, and it’s safer to use for the environment. However, these formulas can be slightly weaker than commercial-grade ones because they don’t contain a lot of the harsh chemicals that the other products do.
Clean grout can be an ongoing struggle, but a cleaner will effectively strip out any contaminants that can cause discoloration while helping to seal your floors to prevent a lot of staining going forward.
Keeping your grout clean and looking like new is important to making your kitchen look clean. I’ve outlined several quality grout cleaners for you to compare. The buying guide will help you pick out the best cleaner for your needs without breaking your budget, and you can use them to restore the bright, clean, and new look to your tile.
