Choosing the Right Chemical
Chemical selection is critical with grout and tile. The wrong product can dissolve grout, etch natural stone, or leave a residue that attracts more soiling.
| Soiling Type | Recommended Chemical | Avoid |
|---|---|---|
| General dirt and grime | Alkaline all-purpose cleaner or neutral floor cleaner | Bleach as a first resort — it whitens but does not deep clean |
| Mould and mildew | Fungicidal cleaner or diluted bleach on ceramic and porcelain only | Bleach on natural stone or coloured grout |
| Grease and fat (commercial kitchens) | High-alkaline degreaser with dwell time | Neutral cleaners — insufficient strength for grease penetration |
| Limescale and mineral deposits | Diluted acid-based descaler on ceramic and porcelain only | Any acid on natural stone, marble, or travertine — causes permanent etching |
| Heavy ingrained soiling in grout | Specialist grout cleaner with agitation | Abrasive powders that damage grout surface |
Golden rule: Never use an acidic cleaner on natural stone or unsealed cement grout. Always check the tile type before selecting your chemical.
The Right Tools
- Grout brush: A stiff-bristled narrow brush designed to agitate soiling from grout joints. Essential for deep cleaning.
- Deck scrub brush: For scrubbing larger tiled floor areas. Use with an alkaline cleaner and allow dwell time.
- Steam cleaner: Effective on ceramic and porcelain. Loosens soiling without chemicals. Not suitable for natural stone as heat and moisture can cause damage.
- Rotary scrubber with grout brush attachment: For large commercial tiled areas. Significantly faster than hand scrubbing.
- Microfibre flat mop: For rinsing and finishing after cleaning. Removes chemical residue without over-wetting.
Correct Technique
Follow this sequence for best results on tiled floors:
- Sweep or vacuum first to remove loose debris
- Apply your chosen cleaner at the correct dilution and allow adequate dwell time — at least 3–5 minutes for ingrained soiling
- Agitate grout lines with a grout brush or rotary scrubber
- Rinse thoroughly with clean water — chemical residue left on tiles attracts soiling faster
- Dry the surface or allow to air dry fully before foot traffic
Dwell time matters. Applying a cleaner and immediately scrubbing gives the chemical no time to work. Allow it to penetrate before agitating for significantly better results.
