1. Everbuild Forever White Grout Reviver

The best overall grout cleaner

Size: 200ml (x2 bottles) | Works on: Wall and floor tiles | Ready to use?: Yes

Easy to use
Long-lasting protection
Antibacterial coating
Sponge applicator could be more effective

If you really don't like cleaning grout, and you're looking for a cleaner that lasts a long time, look no further than Everbuild Forever. 

This cleaner comes in a pack of two 200ml bottles and contains a mould shield to provide long-lasting protecting against bacteria, mould and mildew. It's designed to cover approximately 20m2 of tiles.

It also features an antibacterial coating called SteriTouch which helps to fight off discolouration and restore dirty grout to a bright, white finish. It doesn't get rid of grime, however. 

What's more, it's easy to use. Simply apply to the grout lines using the applicator, leave it to dry (which takes around an hour) and wipe away any excess residue with a damp cloth.

2. UniBond Grout Reviver Sponge Pack

The best at whitening up your grout

Size: 125ml | Works on: Wall and floor tiles | Ready to use?: Yes

Powerful whitener
In-built sponge applicator
Doesn’t get rid of grime

While the UniBond Grout Reviver isn't specifically a grout cleaner, it is an excellent anti-mould product that serves as a great fix for restoring your grout. 

You can buy the reviver separately, but it's worth paying slightly more for the grout revival pen bundle. The UniBond pen helps to refresh and restore old grout on wall and floor tiles in bathrooms and kitchens. And buying the pen as part of the sponge pack means you get an in-built sponge applicator, making the product easier to apply.

It takes up to around an hour to see the results, and once it’s ready you’ll be left with a water-resistant, fresh white coat of grout. The UniBond pen is only suitable for use on fully glazed ceramic and porcelain tiles, however, and doesn’t get rid of grime.

How to Choose the Best Grout Cleaner

Choosing grout cleaner for your home will depend on several factors, such as:

  • The surfaces it can be used on
  • What the product's specifications are
  • How significant the dirt is in your grout
  • How easy-to-use you need it to be.

Some cleaners are designed to specifically remove mould and mildew, but others are best suited to tackling grime. A lot of dirt can grow in our grout, so knowing which one is best for you, and the work surfaces you have, is important.

Applying grout cleaner can be a pain, there's no getting around it. It doesn’t always work first time, and heavy duty models - as effective as they are - can cause skin irritation if you’re not properly protected. 

Make sure you know, therefore, how easy a product is to use before you buy, so that you’re not left uncertain before applying. What's more, be sure to read the instructions so that you know what to expect during the cleaning process. 

How to Prevent Mould and Mildew

You don't want to be regularly scrubbing at your grout to banish mould and mildew, even if the grout cleaners above make it a much easier job, so try these tips throughout the year to keep mould and mildew at bay. 

Ensure good ventilation: in bathrooms or wet rooms, removing heat and moisture (such as from when you've showered) can help to prevent the moist conditions needed for mould and mildew to grow. Open a window while showering or buy one of the best bathroom extractor fans

Keep your tiles dry: it can be surprising at the end of the day to see how wet your bathroom (and even your kitchen) can be, so invest a few minutes each day into drying your tiles with a towel to extend the time between deep cleanings

How to Clean Your Grout

Before you use your grout cleaner for the first time, consider your own safety as well as the safety of anyone else in your house.

Follow these simple rules to ensure that you use your cleaner properly:

  • Carefully read the instructions of your product before use 
  • Always wear protective clothing, including gloves and goggles 
  • Spread grout onto the tile and scrape it into joints using a squeegee or float
  • Avoid scrubbing the cleaner into the grout too hard, which could dislodge the actual grout
  • Use a small toothbrush, or similar brush, to clean any awkward areas
  • Rinse the cleaned area thoroughly, using a shower head, for example
  • Repeat the treatment, if necessary.
  • Use one of the best bathroom sealants to seal the grout
