Cleaning Grout Lines

The best way to get rid of grout grime is by using a specialized grout brush and a suitable cleaner. Whether it’s the bathroom floor or kitchen walls, it’s crucial to get into this area.

A grout brush is small but has rough bristles. The small size makes it the perfect tool for this small area. They come in various shapes and sizes but look for one with a comfortable handle since you’ll need to exert some pressure while cleaning.

How Often Should You Clean the Grout?

Deep-cleaning the grout isn’t an everyday task. It is, however, essential to look out for mold or mildew as these tend to build up in these areas. They can trigger illness in allergic individuals (1).

How often the grout requires cleaning depends on the area’s exposure to moisture. So bathroom tiles, whether floor or wall, tend to need a scrub more often.

A good rule of thumb is to clean the grout when it’s beginning to look discolored or dirty or once a month when doing a deep clean.

The Do’s and Don’ts

Here are some top tips when it comes to cleaning grout:

  1. Use an alkaline solution.
  2. Avoid oil- or wax-based cleaners.
  3. Seal your grout.

1. Alkaline Solution

According to the Tile Council of North America, the best way to clean grout is with an alkaline solution (2). Some people might recommend using either baking soda or vinegar to tackle the stains. However, experts highly advise against this.

Grout is mainly a mixture of sand and cement. Sand is, for the most part, unaffected by cleaners, but cement is alkaline-based and will dissolve if exposed to acids. Baking soda and vinegar are high in acids, making them an unfit solution for grout cleaning (3).

2. Oil and Wax-Based Cleaners

Unsealed grout can absorb soap and stains, making them tough to remove. Therefore, to avoid staining, you should stay away from oil- or wax-based cleaners since these will leave a thin film behind.

Any soap, for that matter, could stain, so it’s essential to wash the area off with water afterward.

3. Seal Your Grout

If you have unsealed grout, you might want to consider sealing them. This isn’t a difficult job; you should be able to do it yourself without any problems. Some grout cleaners also work as a resealer.

How to Find the Best Grout Cleaners

Finding the right cleaner requires a few tests and some consideration. Here are some key points to consider.

Cleaner Efficiency

When we talk about an efficient grout cleaner, we mean one that does the job quickly and is easy to use. Depending on what you prefer, there are various applications available.

  • Direct application: Some products allow you to spray the solution directly onto the troubled area conveniently. Then, you can either scrub or wipe the grime away.
  • Concentrate: Other products are highly concentrated. This means you have to make a solution of the product and water. These come with instructions on how much soap per gallon or quarts of water you use.

The next thing to consider when determining the efficiency of a product is time. How long does the formula have to sit? Does it require a lot of scrubbing, resulting in a more extended session? The most efficient formula will work quickly as it’s applied and won’t need too hard a scrub.

Safety Is Paramount

Even if you choose a product marked “safe” or with a low pH level, it’s still crucial to stay protected.

  • Wear safety gear: Grout cleaners are generally considered harsh chemicals. You should, therefore, wear protective gear such as gloves, goggles, and masks.
  • Correct storage: Some formulas must be stored at a specific temperature and away from direct sunlight. These are also things to consider when choosing a storage spot.

Stay Safe

Always store cleaners out of reach from children and pets. Choose higher locations such as overhead cabinets, or keep the products in a locked cabinet.

The Best Grout Cleaners of 2022

Here’s our list of seven great grout cleaners.

1. Grout Cleaner and Brightener by ZEP

Best Brightener Grout Cleaner

When you need to give your bathroom floor a deep clean, ZEP has you covered. Its grout cleaner will lift dirt, mold, mildew and restore your floors to nearly new condition.

The product contains a professional strength of acids, making it a worthy contender against grime. Rust stains can be a common problem in some regions of the bathroom, and they can seem impossible to get off. However, this potent formula is designed to eliminate these problems with little to no scrubbing.

A small hole in the top makes the ZEP convenient to use. It also minimizes potential exposure since all you have to do is pour a small amount in the area needed.

Still, the potent formula does mean you have to take a few precautions when using the product. For one, you must wear protective gloves. ZEP also advises you to wear long sleeves and pants to avoid any exposure.

Pros

  • Brightens grout lines and tiles, so your bathroom looks as good as new.
  • Doesn’t require rough scrubbing, which saves you energy.
  • Safe for colored grout as well as white grout.
  • Convenient squirt top makes the application extremely straightforward.

Cons

  • Very “aggressive” product with harsh chemicals. The potent formula might not suit every homeowner.

2. Soft Scrub Gel Cleanser

Best Grout Cleaner for Multiple Surfaces

Having one cleaning product that can clean all surfaces, such as grout and stovetops, can save time and money. This all-around gel can take on both the kitchen and bathroom.

It contains bleach but is non-abrasive so that it won’t harm anything except dirt. A great thing about the gel is that it’s fast-working. The opening is a convenient squeeze top that allows you to apply the product more carefully.

Apply it straight onto the surface or to a damp sponge. Give it a little rub and rinse it off. If the stain is a little tougher, allow the formula to soak for no longer than a minute, then scrub.

Because of the bleach, you mustn’t get any of the product on clothes, carpets, or fabrics. Prolonged exposure to materials like metal and plastic can also cause discoloration. If you’re unsure about an area, first do a small test run in an inconspicuous place.

Pros

  • Multi-purpose product that you can use on grout and stovetops.
  • Non-abrasive formula protects your surfaces from damage.
  • Easy to use, thanks to the convenient squeeze top.
  • Fast-working formula cleans in less than a minute.

We don’t all have time to scrub grout lines, so when we need the job done quickly, this pen could help. Clorox has come up with a genius way of tidying dirty grout minutes before guests arrive.

Unlike other grout pens, this one treats the stains instead of covering them up.

You get four pens in the packet, and they’re easy to use. Each one has two ends; one is a thin point that applies the bleach to even the tiniest crevices. The other end is a broad scrubber to rough the stains. When you’re done, wipe the area clean or rinse with water.
