How to clean grout and remove mould

Grout loves to hang onto grime and mould like it’s a long-term relationship. Luckily, breaking them up is easier than you think with the right clean.

 

What you need

✔ Bathroom & Shower Cleaner with Foaming Spray Bottle
✔ Grout Brush
✔ Bathroom Cloth (optional)

 

Step-by-step guide

Step 1
Spray grout lines with Bathroom & Shower Cleaner and leave for 2–3 minutes to let the enzymes get to work.

Step 2
Scrub back and forth with the Grout Brush to lift mould and grime from the grout.

Step 3
Rinse with your shower head, or wipe clean with a Bathroom Cloth.

 

Pro tip

• This method works on grout only—if mould has crept into silicone sealant, it sadly can’t be scrubbed away.

 

Safety first: Always ensure your bathroom is well ventilated when dealing with mould. Wear appropriate safety equipment (e.g., gloves, mask) for protection.

 

Other notes

Regular upkeep (weekly wipe-downs with Universal Cleaner) stops mould before it starts.
