Best Grout Cleaner UK

When it comes to bathrooms, kitchens and other “wet” and practical rooms like that in your home, there is nothing better than tiled surfaces. They not only make the room look great, add a reflective quality, but are much easier to clean than other options. Have you noticed though, that the grout that holds the tiles in place and finishes them off looks smart and striking, in the beginning?

Over time, though, it’s a very different story. Grout can absorb a lot of moisture and dirt, grime, and even mould, mildew and limescale can start to build upon it. When this happens, the grout looks anything but smart or striking. It looks tatty, tired and just plain dirty. Which in turn makes the whole room feel aged and neglected.

Try as you might to clean it with traditional cleaners and solutions, that you use for other surfaces throughout your home, it doesn’t work. You need to invest in special grout cleaner that has been devised to target those surfaces. With so many out there, though, how do you know which is best?

Leave it to your friends at Recommend Buys. We have researched and picked out what we think are the top 10 grout cleaners. In this guide, you will not only find our reviews, but also a handy buying guide that fills in any gaps you may have with choosing the right one.

Top 10 Best Grout Cleaners UK

1. HG Grout Cleaner, 500ml

The first product in our list is the very popular HG Grout Cleaner. Made by the reputable Dutch company that has for a long time been a leading name in the cleaning products industry, dating back to when it was first established by the original owner, Hakan Gap. This is a readymade formula that promises to make your grout great again, by removing all that stubborn dirt between tiling. If you are looking for a solution to dirty grouts that does not involve making a diluted solution up in another container or other convoluted instructions and simply want one that you can use straight away, this is the one for you.

It comes in a trigger spray bottle and to apply this cleaner you just need to spray the solution over the grout that you want to clean and then let it sit for a few minutes before returning to it and scrubbing at it with a brush. Finish by using a slightly damp cloth that’s been dipped in lukewarm water to dislodge any of the dirt lifted by the cleaner and then allow it time to dry.

2. Black Diamond Ultimate Grout Cleaner

Next, we have the so-called Ultimate Grout Cleaner from Black Diamond. Is it really as amazing as they think? Well, we can’t say that for sure, what we can tell you is a little more about it. Straight off the bat, one of the big selling points of this grout cleaner is that it is 100% acid-free, so will work safely on coloured and white grouting.

Whether you are looking to clean soap scum, oil, dirt or grease from marble porcelain or simple ceramics, this is a great option.

This also comes readymade, so there is no mixing or diluting. You just point the spray at the grout you wish to clean, spray and leave for 1 to 3 minutes, before working at the solution and surface with a brush to remove any embedded debris, then rinse the area off with fresh water.

While some people seem to suggest that it is not as good as is suggested by the company, others suggest working hard with it. It won’t shift the dirt on its own, basically.

Acid-free[/i2pros][i2cons]Not great for removing water spots and calcium from showers[/i2cons][/i2pc]


3. Unibond Grout Reviver Sponge Pack, 125ml

Unibond is a name that most people are familiar with, and with good reason, as they have a reputation for developing, designing and producing high-end products at affordable prices for the cleaning and DIY industries. This Grout Reviver sponge pack is no exception. Rather than simply being a cleaner, it will actually whiten the grout, giving it a new and gleaming lease of life.

Like the previous two products, this is also readymade and can be used as soon as you open it. It even has a sponge applicator to make it less messy and easier to apply. After you have applied it, you just need to wait 60 minutes and remove any excess dirt and debris with a damp cloth to see the excellent results. Importantly though, it is only suitable for fully glazed porcelain and ceramic tiles.

4. LTP Grout Stain Remover, 1-Litre

Another company with a hugely successful history in the industry are responsible for the next grout cleaning product we want to discuss, LTP. The company have been in the business for almost 20 years, Anthony Robb the owner of the Wellington Tile Company was beginning to import Portuguese terracotta and trying to give it an antique look and feel before selling it.

After putting together his own formula to achieve this, he also worked on grout cleaners. As the terracotta in question was branded Lionheart Terracotta, the sealers and cleaners became Lionheart Terracotta Products, which when shortened becomes LTP.

This Grout Stain Remover from the company is an excellent solution that can remove grout, limescale and cement residue. It is incredibly effective when working to get rid of the build-up of mineral salt. One of the great things about Grout Stain Remove is that it is not just good for using in the bathroom and kitchen areas, as it can be used for patios and paved areas outside.

You can use the solution on various materials like unglazed and glazed terracotta, quarry tiles, ceramics and even some stone (those that are acid-resistant, in particular).

5. Everbuild Forever White Grout Reviver, Arctic White, 2 x 200ml

From Everbuild, we next have the Forever White Grout Reviver in Arctic White. Again, this is a ready-to-use solution that will help to clear dirt, grime and stains from grout, while whitening and brightening them to make them look as good as new. One of the key components of this mixture that sets it apart from others is the patented SteriTouch which helps provide a protective layer for the grout that will help prevent further discolouration caused by mould, mildew and bacteria growth.

It is relatively easy to use the formula. You take the included applicator and apply it directly onto the grout lines and wait for it to dry. Once it has dried you can use a damp cloth to wipe away excess residue.

Considering how affordable this product is, it’s amazing that you get not just one but two.

6. Pro-Kleen Tile Grout Cleaner

Next, we have what many consider to be the most effective and powerful grout cleaners available – Pro-Kleen Grout Cleaner. This consists of exceptionally concentrated formula, meaning that you can make even just a little go a very long way. It is particularly useful for cleaning all those black and brown stains that have built over time and been caused by soap scum, fungus and mould.

Although it is a concentrated solution, it is ready to use when it arrives, so you just need to point it at the affected areas of grout and spray and then give it enough time, about 10 to 20 minutes for it to work its magic. Once you’ve left it to sit, you then need to just rinse it off using water and a sponge.

The first time you use it, if you have very stubborn stains to take care of, it may require more than one application. If you start using it regularly though, you may eliminate or greatly reduce the need to completely re-grout between your tiles.

Pro-Kleen have devised this product so that it will work on a multitude of different surfaces. For the price, considering you get the spray bottle and the larger container, we think it’s a very good deal.

7. All for Stone XtremeClean Heavy Duty Cleaner for Stone, Tile and Grout

Next, we have another highly concentrated, top-grade cleaner called XtremeClean from All for Stone. This one is a little different from the others we have highlighted so far, as it does need to be diluted appropriately, depending on what surfaces you are working on and cleaning.

Due to the toxic nature of the ingredients, therefore, it is necessary to take extra special care and more safety measures when using this product. It will, though, remove all manner of grease, ingrained grime, dirt from grout and other surfaces.

As it is so strong, it can work well in neglected areas or on surfaces that have been heavily soiled. Not only that, but it can actually strip floor finishes and waxes too. This is probably the one cleaner that will work on most surfaces in and around your house, including pavers, concrete, terracotta, ceramic tile, grout, porcelain, and natural stones to name a few.

There are extensive instructions for use that accompany it, which you should always follow. For the strength of cleaning power it offers, we think this is an especially great investment.

Works on most surfaces[/i2pros][i2cons]Very toxic needs proper care when using it[/i2cons][/i2pc]


8. SmartSeal Grout Magic Pre-Treatment Surface Primer

Made by SmartSeal, the next product in our list is actually designed to be used before you use their Grout Magic solution. However, it can be used as a cleaner in its own right. The Pre-Treatment Surface Primer will clean and prepare grout, removing stubborn and built-up stains, dirt and grime quickly and effectively.

You can use it around enamel and plastic showers and baths without worrying about it ruining or damaging the surface. As it comes in its own spray bottle, it is premixed and ready to use as soon as you open it. One word of warning though, you should only use it to clean and prepare non-porous tiled surfaces.

Grout Magic, the other product that this is a pre-treatment for is a solution that seals and re-colours grout that has seen better days, to eliminate the need to completely replace it.

9. Stardrops Pink Stuff Paste, 500g

Stardrops are a company that has been in operation for a couple of decades now, devising, formulating and producing high-quality cleaning products for various different rooms and surfaces in and around the home. One aspect of Stardrops products and solutions that makes them stand out is their focus on using natural and organic ingredients, without pricing them too highly.

When it comes to grout cleaners, although they don’t necessarily have a grout cleaner, their amazing Pink Stuff cream cleaner works just as well. It is actually marketed as being an all-round cleaner and can help to breathe new life and clean anything from barbecues to saucepans and, of course, ceramic tiles.

As it does not contain any harsh chemicals or abrasive ingredients, it works hard on stains while being gentle on the surfaces you use it on.

It’s also incredibly easy to use and you can start using it without mixing it or diluting it, the moment it arrives.

10. Everbuild Forever White Grout Reviver and Mould Shield, Arctic White, 200ml

The last product in our guide is the second from Everbuild. This is more or less the same product that we featured earlier in our list, with the addition of a mould shield. Which is worth considering if mould is a big problem in your property. You simply apply it in the same way as the other product and as well as cleaning and whitening the grout, it will coat it in a protective layer that will stop it from discolouring and also stop mould from growing on it in the future.

Best Grout Cleaner UK – Buying Guide

Although we hope we have given you enough variety to choose from when finding the best grout cleaner, we understand that an overview of products may not be enough. That is why we have also included this buying guide. In it, you will find extra helpful information about the things you need to consider when buying grout cleaner.

Types of Tiles

You need to be careful when choosing a grout cleaner because some are not suitable for all types of tiles. Some can etch the surface of the tiles and even cause them to lose their polished finish. With some tiles made from stones like marble and granite, you may need to invest in a specially formulated product.

Coloured Grouts

If you have coloured grouts that match the unique colours of the tiles, you need to be sure to avoid any grout cleaners that contain bleach as this will remove the colouring. Acid grout cleaners may be better as they are less likely to remove the colour.

Tile and Grout Location

You also need to think about where the tiles and grout are located. Some cleaners require that you apply the mixture and then leave it to soak for a designated time. These types of grout cleaner are better suited to wet rooms and areas like the bathroom. Therefore, always think not just about the grout and tile itself but the area surrounding them and whether the cleaner could adversely effect on it.

How Easy is it to Use?

Although there are a lot of grout cleaners out there that seem to do the same job more or less as one another, you need to realise not all grout cleaners are made equally. Some are much easier to use than others, for starters. With the vast majority of the products we included in our list, we picked out those that needed minimum preparation, except for one (that was picked because it is one of the best and we didn’t feel we could give as complete and honest a list without it), whereas some need diluting.

It all comes down to what you prefer and like, really. If you want an easier and quicker job, then stick to grout cleaners that come premixed and ready to use with an applicator or spray gun bottle.


It should never be top of the list of your priorities, but you need to consider the cost of grout cleaners when choosing the right one for your home and needs. Some are far more expensive than others. Moreover, you need to think not just about the initial cost, but their actual value in terms of how effective they are at doing the job they were designed for.

You won’t want to spend your hard-earned money on an expensive grout cleaner that doesn’t perform well, just as it would be false economy thinking you are getting a bargain-priced cheap grout cleaner if you need to buy another and go through the process again because it failed.

Understanding the Different Types of Grout Cleaners

You will notice pretty quickly when looking through the available grout cleaners on the market and even those in our list, that there are a variety of different kinds of products called grout cleaners. Some of the most common and popular are:

  • Acid-Based – These are very chemically strong and usually do not require much scrubbing if any at all. The acid in the formula eats away at the top layer of grout and in the process removes the dirt and grime you want to get rid of to reveal a clean layer underneath.
  • Bleach-Based – self-explanatory really, but these cleaners use Bleach and need a little bit of scrubbing. If you have grout that was originally white, a bleach-based grout cleaner will help to whiten it and remove any dark stains.



Sometimes it’s not really about how much you spend, it’s how you spend the money when it comes to decorating and working on the décor around your house. With the right grout cleaner, you can give any room with tiling a real refresh and refurb. Rather than retiling or even just re-grouting, investing in one of the great grout cleaners, we have discussed is the easiest and most cost-effective way to breathe new life into them.

As you have seen, you don’t need to spend a lot, as it’s more about spending wisely. You need to choose the right product for the right tile material and the application method that suits you. Although there are a lot of great options out there and you may find it difficult to choose one from the other, we have hopefully made things a little easier for you.

Even if you are still not ready to purchase any, you at least understand the important aspects you need to consider when picking grout. This should help make what may have otherwise been a nightmare of a job into something less stressful and a whole lot quicker.
