General solutions for dirty and discoloured grout

In addition to HG products, some household methods may help. Use these with care:

• Clean grout using a paste of water and baking soda, apply, leave briefly and scrub thoroughly.

• Use white toothpaste (not gel), apply to grout, leave for around 30 minutes, then scrub and rinse.

• A solution of water and lemon juice may help remove deposits due to its mild acidity.

These methods may not always be effective and may carry risks. Specialist products generally provide better results.

Causes of dirty grout

Grout can become dirty due to multiple factors:

• Moisture leading to mould growth and discolouration

• Dirt and dust build-up over time

• Wear and ageing

• Incorrect cleaning methods

To prevent discolouration, ventilate areas well, clean regularly with suitable products, avoid harsh or abrasive cleaners, and consider sealing grout for added protection. Regular maintenance helps preserve grout appearance and extends its lifespan. Proper ventilation reduces moisture accumulation that leads to mould and discolouration. Using appropriate cleaning products prevents damage while maintaining cleanliness.
