This impressive cleaner 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.

UniBond's sponge pack is cost effective and easy to apply

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

Easy to apply
Doesn’t get rid of grime

The UniBond Grout Reviver isn't specifically a grout cleaner, but it is an excellent anti-mould product that serves as a great fix for covering up stubborn stains.

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 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:

  • Always wear protective clothing, including gloves and goggles 
  • Carefully read the instructions of your product before use
  • 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 showerhead, for example
  • Repeat the treatment, if necessary.

Choosing the Best Grout Cleaner

Your grout cleaner of choice will depend on several factors, such as:

  • The surfaces it can be used on
  • What the 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. There’s a lot of dirt that 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. 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. So make sure that you know how easy a product is to use in advance, so that you’re not left uncertain before applying, and be sure to read the instructions so that you know what to expect during the cleaning process.
