What to Look for in a Grout Cleaner
Types of Surfaces
For example, some cleaners are formulated for kitchen or shower grout. Whereas others are for use on any grout type or tile surface.
Some grout cleaners, like this Bar Keepers Friend Soft Liquid, can also clean cookware or cooktop surfaces.
There are also many different tile materials such as porcelain, marble, ceramic, or natural stone. So make sure your grout cleaner is safe to use on your type of tile as well as grout.
Ceramic and porcelain tile surfaces tend to be safe from the effects of harsh cleaning chemicals. But, marble and natural stone are more delicate and may be affected by some cleaning chemicals.
Always read the product description to make sure that the chemicals in your cleaner are safe for your tiles. For example, this Aqua Mix Heavy Duty Tile and Grout Cleaner is safe on marble and limestone.
However, some grout cleaners have other purposes, such as mold and mildew removers. For example, this Goo Gone Grout Cleaner can clean mold and mildew grout stains.
Some cleaners also remove 99.9% of bacteria, germs, fungi, and viruses from your surfaces. So consider your cleaning needs to find the best cleaning product for your grout.
For example, some cleaning formulas specifically target white grout. These grout cleaners ensure that the chemicals don’t taint the color of your grout during cleaning.
Whereas other cleaners may have chemicals that can damage or stain colored grout. So make sure that your grout cleaner is suitable for your grout color.
There are three different ways to apply cleaner to your grout. These include a spray and wipe application, a scour and brush, or an apply and rinse formula.
Spray and wipe products don’t require scrubbing. So they can save you a lot of time and energy while cleaning.
But, these cleaners tend to contain harsh cleaning chemicals or bleaching agents that may damage or discolor your tile grout. So they may not be the best option for cleaning delicate grout surfaces.
Plus, they tend to drip on vertical surfaces. So you often need to reapply spray products when you’re cleaning walls or backsplashes.
Grout cleaners that require scouring with a grout cleaning brush can add effort to your cleaning process. But, they are especially effective for cleaning heavily soiled grout and surfaces.
For example, this Magic Grout Cleaner requires scrubbing.
Lastly, some products allow you to clean with the direct application of a pen and simply require rinsing after applying. For example, this Clorox Bleach Pen is a fun and easy-to-use grout cleaning tool.
These cleaners are ideal for spot cleaning grout. They don’t require any scrubbing or wiping, but they need rinsing after application.
However, some cleaners need time to agitate and lift grime and discoloration from the grout surface. So make sure you follow the instructions for your grout cleaner to allow the best time for optimal cleaning results.
For example, this Soft Scrub Gel Cleanser chemical cleaner contains bleaching agents. There are also no requirements for manufacturers to list the ingredients for chemical cleaners.
But, these cleaners tend to be more effective for cleaning. So when you’re buying a chemical cleaner, always look for EPA’s safer choice label.
EPA reviews the chemical ingredients in these products to ensure they meet strict safety criteria. They test every ingredient to make sure it’s safe for your health as well as the environment.
So a product with an EPA safer choice label will ensure that your cleaner is safe to use for cleaning. For example this Krud Kutter KK32 Original Cleaner has a safer choice certification.
Grout Cleaning Tips
Follow these cleaning tips for the best grout cleaning results.
- To prevent surface build-up, make sure you clean your grout regularly. This is because sealing your grout doesn’t guarantee protection against build-up on the surface.
- Avoid using harsh cleaning tools like steel scrubbers or metal scouring pads. These may damage your grout surface. Instead, a better option is to use a scrub brush like this Casabella Smart Scrub Heavy Duty grout brush.
- We don’t recommend using vinegar to clean your grouts. Since it’s acidic, it can dissolve the cement on your grout, even if your grout is sealed. This is because cement is alkaline and dissolves in acid the same way baking soda does.
- You can use a sealant on your grout to prevent it from staining or becoming dirty. To do this you can apply either a topical or penetrating seal. A topical seal stays on the surface while a penetrating seal soaks in. Penetrating sealants tend to be best for grout on floor tiles as they can withstand heavy foot traffic. Whereas topical seals may be worn off by foot traffic over time and are best for walls or backsplashes.
