Tile and Grout Cleaning: How to Restore Bathroom and Kitchen Floors

Grout is porous by nature and absorbs everything it comes into contact with. Dirt, soap, mould, body oils, and cleaning residue all accumulate over time, turning once white grout into a dingy grey or black. Here's how to restore it to its original colour.

Why Grout Discolours in Melbourne Homes

Melbourne presents some unique challenges for keeping grout clean. Understanding the causes helps you prevent future discolouration.

• Melbourne's hard water leaves mineral deposits that build up in grout lines
• Soap scum and body oils from showers accumulate gradually over months
• Mould and mildew thrive in the humid grout lines of bathrooms
• Foot traffic grinds dirt deep into the porous grout surface
• Incorrect cleaning products can actually make discolouration worse

DIY Cleaning Methods That Work

For light discolouration, you can achieve good results at home with the right approach.

1. Make a thick paste using baking soda and water
2. Apply the paste along grout lines using an old toothbrush or grout brush
3. Spray with undiluted white vinegar and allow it to fizz for 5 minutes
4. Scrub vigorously along the grout lines
5. Rinse thoroughly with warm water and dry completely

When to Call the Professionals

If your grout is dark grey, black, or has visible mould growth that returns within days of cleaning, DIY methods won't be enough. Professional tile and grout cleaning uses specialised equipment including:

• High pressure steam cleaning that reaches deep into porous grout
• Commercial grade grout cleaners formulated for specific stain types
• Rotary scrubbing equipment that covers large areas efficiently
• Professional grout sealing that provides long lasting protection against future staining

Prevention Tips for Lasting Results

• Seal your grout annually with a quality penetrating sealer
• Wipe down shower tiles and grout after every shower to prevent soap buildup
• Use exhaust fans during and after showers to reduce moisture
• Professional caulking at tile junctions prevents water from getting behind tiles
• Avoid bleach based cleaners on coloured grout as they can cause fading
