Cleaning your grout is not an everyday job, or even necessarily an every week job, but it sure does make a difference. Grout is made of sand and is porous so is prone to getting very dirty from limescale (check out our round-up of the best limescale removers), black mould, and perhaps even bath crayons which one parent in our Top Testers Club said had been used by their child to colour in the grout.


To help you find a grout cleaner that works, we asked our Top Testers Club which product they use and recommend to clean their grout. When testing and selecting the best grout cleaners, we considered effectiveness, versatility, suitability and value.

What to consider when choosing a grout cleaner

Grout colour – If you have coloured grout, then you need to be careful when choosing a grout cleaner. Most will be okay but if you're using a grout pen (such as the one featured in this article) then it may come out a different colour to your grout, so do pay extra attention to this.

Mould and mildew – As previously stated, mould and mildew are common culprits for dirtying up your grout. If this is the case, then a regular grout cleaner may not be enough, you might need to use a specially designed cleaner to tackle the mould and mildew.

Versatility – Many of the grout cleaners featured in this list are versatile and can be used to clean other things too. This makes the product good value and prevents having lots of different cleaning products taking up space in the cupboard.

Capacity – If you're considering value, it's also a good idea to look at the capacity of the product. A larger capacity means it will last you much longer so you may be better off buying a more expensive option that will last you longer.

5. Unibond Grout Reviver Pen, £4

– Best for grout revival

Capacity: 7ml | Suitable for: Any grout

This pen allows for easy and precise application, just shake the pen and apply to the grubby grouting. Home tester Carla said, "If I do have any stains that for some reason won't go then I use Unibond Grout Reviver."

The pen is an Ice White colour so will not work for reviving coloured grout. The 7ml pen should be able to revive approximately 60m of grouting.

It dries within just 60 minutes, so no need to keep the shower or bath off limits for days. The pen offers triple protection against mould and is waterproof, making it suitable for use in bathrooms.

Cons: Not suitable for coloured grout, does not clean

Available from: Amazon, Wilko and Dunelm

– Best for limescale

Viakal Limescale Remover Spray

If your grout is looking a little unloved, it could actually be limescale causing the problem, especially if you live in a hard water area, prone to scale.

Parent tester Rebecca said, "We use Viakal Limescale Remover Spray and a good scourer, we live in a really hard water area and it's the only thing that works really well without too much effort."

Viakal aims to eliminate 99.9% of bacteria and 100% of limescale. It can be used regularly to try and protect the grout from deteriorating.

Pros: Removes limescale, easy to use, requires minimal effort
Cons: Only works if grout is dirty from limescale

Available from: Wilko, Sainsbury's and Asda

7. Cillit Bang Black Mould Remover, £3.50

Cillit Bang Black Mould Remover

Capacity: 750ml | Suitable for: Bathroom and living room

It has a combination of cleaning agents and disinfectant to try and get rid of 100% of black mould. It doesn't require much effort either, meaning no need to scrub, simply spray on, leave for a few minutes and wipe off with a clean cloth or sponge.
