A grout cleaner is the best way to restore tile grouting to its original finish and most formulas can be used anywhere around the house. Although most formulas don’t require scrubbing, tough stains and dirt can be agitated using a toothbrush or a dedicated cleaning brush for the best possible chance of returning the grout to its original finish.

To assist you in selecting a grout cleaner, our handpicked selection lists top-performing formulas, chosen based on our first-hand experience cleaning floor and wall grout in bathrooms and kitchens. Our testing and up-to-date research further ensure the quality of our recommendations.

How The DIY Works Team Tests & Rates Grout Cleaners

Whether we are cleaning grout in a shower cubicle or floor grouting in a kitchen, we’ve tried and tested many different formulas over the years.

The cleaners we’ve used include those from reputable brands in the UK as well as brands that aren’t as popular but specialise in grout cleaners.

Below are some before and after photos taken whilst testing the HG formula listed as the best within this article. As you can see in the second photo, the difference in colour between the cleaned top half of the grout and the bottom half is quite clear to see.

It’s important to note that after spraying the formula, we only scrubbed the grout up and down a few times to achieve these results.

As well as testing many different grout cleaners upon a range of floor and wall grouting, we also based our recommendations on hours of research and several factors. Some of the factors that we considered included the formulation, ease of use, time it takes to activate, coverage, effectiveness on all types of imperfections and value.

1. Best Overall: HG Grout Cleaner Ready-To-Use

(How We Review →)

HG are well-known for their affordable yet highly effective formulas and this grout cleaner is a great example. It’s a ready-to-use solution that powers through dirt to restore the grout’s original colour.

To use this grout cleaner, simply spray it onto the grout, agitate it with a brush and allow it to get to work. After approximately 15 minutes, simply rinse away the residue with water to reveal the grout.

Pros
  • Concentrated formula
  • Powerful cleaning agents
  • Suitable for floor or wall grout
  • Ready to use from the bottle
  • Takes 15 minutes to activate
Cons
  • During testing, we found that we went through a lot of the formula

To conclude, the HG Grout Cleaner is by far the best formula for the money and it cannot be beaten on price. It’s ready to use from the bottle and it easily cleans all grout joints upon any floor or wall tiles.

2. Best Heavy Duty: LTP Grout Stain Remover

(How We Review →)

If you require a more heavy duty grout cleaner, the LTP formula is a great option to consider. It’s suitable for use upon ceramic, porcelain, tile and stone and it can be used to remove cement, limescale and of course, grout residue.

Although this cleaner is primarily used to remove grout stains on top of tiles, when used directly on grout, it effortlessly removes dirt and restores the grout back to its original colour.

Pros
  • Suitable for interior or exterior use
  • Fast acting formula (activates within 5 minutes)
  • Large 1 litre bottle that can be diluted
  • Can be agitated for stubborn dirt or stains
  • Rinses clear with water
Cons
  • Most expensive formula per ml within our roundup

To conclude, if you are struggling to remove grout stains upon your tiles or extra stubborn dirt directly on the grout, the LTP Stain Remover is by far the best grout cleaner to use. The only drawback is the premium price tag but considering its effectiveness and versatile formulation, it’s worth paying the extra for.

3. Best All-Rounder: Pro-Kleen Tile Grout Cleaner

(How We Review →)

If you are tackling multiple bathrooms or large kitchens, buying a grout cleaner in bulk is highly recommended. The Pro-Kleen grout cleaner is a great bulk buy option to consider and it comes complete with a 5 litre bottle and a refillable 750 ml spray bottle. In terms of its formulation, it’s super concentrated and the 5 litres should last a long time.

According to the brand, their advanced grout cleaner aims to restore the original colour of your grouting and effortlessly remove dirt or grime for a grease-free finish.

Pros
  • Removes brown and black stains
  • Leaves a grease-free finish
  • Restores and refreshes the grout
  • Simple to use and activates within 10 to 20 minutes
  • Suitable for use straight after for stubborn stains
  • Bulk 5 litre bottle and refillable 750 ml bottle
Cons
  • Only available to buy in bulk, which is expensive due to the large volume

Overall, the Pro-Kleen 3-in-1 is a highly effective grout cleaner that’s ideal for removing stains caused by mould, fungus and soap residue. It really does tick all the boxes and in the long run, it’s a more cost effective solution.

4. Best Fast Acting: Black Diamond Ultimate Grout Cleaner

(How We Review →)
Black Diamond Ultimate Grout Cleaner

Another popular grout cleaner that’s used worldwide is by the Black Diamond brand. It’s a fast acting formula that’s completely acid-free and safe to use for white or coloured grouts.

Pros
  • Acid-free formulation
  • Fast acting and provides a deep clean
  • Cleans dirt, grime, grease and oil
  • Activates within 2 to 3 minutes
Cons
  • Requires agitation for the best results

Overall, the Black Diamond Ultimate Grout Cleaner is a fast acting and versatile formula that won’t disappoint. It’s best used with a steam cleaner and it gets to work in just 2 to 3 minutes, which is far quicker than the alternatives.

5. Best Value: Everbuild Forever White Grout Reviver

(How We Review →)

The Everbuild Forever White is a unique grout cleaner that’s applied to the grout lines using an applicator. Unlike the alternatives, it’s a “toothpaste-like” formula that many people may find easier to apply.

Pros
  • Covers up to 20 square metres
  • Restores grout back to a bright white
  • Provides up to 10 years of protection
  • Waterproof finish
Cons
  • Easy to use but time consuming if you need to clean a large amount of grout

Overall, the Everbuild Forever White is a cheap solution for restoring grout and it also benefits from offering long lasting protection against mould, mildew and bacteria. However, due to the small size, you may need multiple tubes if you are planning to clean grout in large tiled areas.

6. Best Value Runner-Up: Problem Solved Grout Cleaner

(How We Review →)

The Problem Solved grout cleaner is a British formulated and manufactured option with an affordable price tag. According to the brand, it gets to work in under 10 minutes and it’s able to remove all dirt, mould and mildew.

Pros
  • Fast acting formula
  • Restores the whiteness to grout
  • Application using a brush or cloth
  • Suitable for wall and floor grouting
Cons
  • Requires agitation for the best results

Overall, it’s a high quality grout cleaner that’s fast acting and provides a long lasting finish. It also benefits from not requiring any hard scrubbing (just lightly with a toothbrush or cloth) and it can be simply left to get to work by itself.

Conclusion

Attempting to clean dirty or stained grout using just soapy water isn’t going to work as well as a dedicated grout cleaner. All of our recommendations listed above are suitable for floor and wall grouting and they take just minutes to get to work. For the best results, we recommend agitating the formula with a brush in order to lift stubborn dirt ingrained into the grout.

Depending upon the amount of dirt, you could also try using a steam cleaner upon the grout beforehand. This will allow the cleaner to be more effective and also have a better chance at restoring the grout to its original colour.
