To use, carefully apply the solution to a pre-wet surface with a sponge or a mop, allow to sit for 3-5 minutes for cleaning, then scrub with a brush, sponge or nylon pad. It can require hard brushing, but once applied it is very fast-acting.


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
  • The product's specifications
  • 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. 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 though the grout cleaners in this list make it a much easier job. Try these tips  to keep mould and mildew at bay. 

Ensure good ventilation: in bathrooms or wet rooms, removing heat and moisture (such as 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 to see how wet your bathroom (and even your kitchen) can be at the end of the day, 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 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 - this 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
