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 tile and grout, 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 grout cleaners until you get the best grout cleaners 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 good grout cleaner will strip the dirt and grim from the grout to make it look like new.
1. Skylarlife Home Mold & Mildew Remover
This is a gel-based grout cleaner that helps to lift mold and mildew from your kitchen, shower, or pool area. This is a fast-acting formula that will cling to tile, grout, and silicone sealant around sinks, windows, and baths once you apply it. 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. It works on a broad range of grout colors from black to white, and you should only need minimal effort to remove the dirt and grime.
Since this is a gel grout cleaner, it won’t slide down any included or vertical surfaces.

This tip also makes it easier to clean up because it won’t accidentally smear it all over your kitchen when you apply it. It claims you won’t have to scrub the grout to remove the grime, and it doesn’t have a strong smell when you apply it.

Grout Cleaner Buyer’s Guide
You want to get a good product when you start shopping for your ultimate grout cleaner, but there are so many options for cleaning grout available that it can take time to narrow down your choices. There are several criteria you can look for in the best grout cleaners, and I’ve rounded up the most important aspects to consider in the ultimate grout cleaner below.
Why Use Grout Cleaners
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 tile and grout. Eventually, this will lead to discoloration, and it can cause your new tile floor or wall to look dirty and unkept. Quality grout cleaners will gently remove this buildup along with some elbow grease while restoring your grout to ensure that it doesn’t look grimy. You usually apply the grout cleaning solution, 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 floor tile grout 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. Also check how it reacts with stainless steel or marble. 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.
White grout is more popular than colored grout, but clean white grout can be an ongoing struggle, but quality grout cleaners will effectively strip out any contaminants that can cause discoloration while helping to seal your floors to prevent a lot of staining going forward.
Besides the best grout cleaners listed above to restore your grout and tile floors to their original color, you can also DIY grout cleaners that can be made with baking soda / hydrogen peroxide, along with a toothbrush or grout cleaning brush to help you get through grout lines and remove mold and mildew.
Whether you have grimy grout or stained grout, 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 on grout cleaners will help you pick out the best grout cleaner for your needs without breaking your budget, and you can use the grout cleaners to restore the bright, clean, and new look to your tile.
