How to clean grout

Cleaning grouting surrounding tiles can make a tired looking bathroom look as good as new. 

Here, NRLA partner Tradepoint (B&Q) explains what you need to know. 

How to clean grout 

Grout is the hard cement used in the joints between tiles to waterproof them and give them an attractive finish. But when it becomes discoloured and dirty, it can impact the appearance of the whole room. 

To clean grout joints, the first thing you need to do is start by giving the whole area a good clean to remove soapy residue, limescale or even speckles of mould. Do this using a non-abrasive pad or brush. 

You then will need to let the grout dry. If the grout is still stained or discoloured, then you can consider using a specialist grout cleaner to help make the grout look brighter. Wear rubber gloves, goggles and protective clothing and make sure the area is well ventilated before you begin. 

Spray the solution on the grout joints and wait for ten minutes for the mixture to activate properly. 

Then, you can use an old toothbrush and scrub away at the grout to help clean it up. You can then rinse off with clean water and dry the area of with an old cloth. Make sure to give time for the joints to dry out. 

Grout still stained? If this is the case even after cleaning, then you may wish to consider using a grout reviver pen. 

Again wearing gloves, gently apply the solution to the discoloured grouting. Make sure you wait at least an hour for it to dry. You can always a apply a second coat if needed. 

How can you prevent grout discolouring? 

It sounds obvious, but cleaning tiles often and wiping down showers and splashbacks each time they’re used can go a long way towards helping keep grouting looking clean and neat.
