Tiles are one of the most practical and attractive flooring choices for modern homes. From elegant porcelain and natural stone to classic ceramic, they offer durability, easy maintenance and timeless style. But over time, everyday life takes its toll — spills, muddy shoes, pets, and mopping with the wrong products can all cause grout lines to darken and tiles to lose their shine.
If you’ve noticed your once-bright floors starting to look dull or patchy, this guide explains exactly why it happens, what you can do about it, and when it’s time to call in the professionals for a proper tile and grout deep clean.
Why tile and grout get dirty over time
Even though tiles themselves are usually non-porous, the grout lines between them are like tiny sponges. They absorb moisture, grease and dirt every time you mop. Over months or years this builds up, leaving grey or brown discolouration that no amount of scrubbing seems to shift.
Common causes include:
Using household cleaners that leave residue behind
Not rinsing mops properly after cleaning
Foot traffic from kitchens, hallways and conservatories
Pets, muddy paws and food spills
Hard-water deposits in bathrooms or utility rooms
Once grime settles deep into the grout, it can trap bacteria and odours — which is why the floor never looks or smells truly clean.
DIY cleaning tips that actually work
You can keep your tiles looking fresher for longer with a few simple habits:
Vacuum or sweep first. This removes grit that could scratch the surface when mopping.
Use a neutral-pH floor cleaner. Avoid bleach or harsh chemicals — these can break down grout over time.
Mop with warm water and rinse often. Dirty water just redistributes soil.
Dry the floor afterwards. Leaving it wet can draw dirt back into the grout.
Spot-clean spills quickly. The sooner you tackle them, the easier they are to remove.
These steps help maintain your floor between professional cleans, but they can’t match the deep results of specialist equipment.
When to book a professional tile & grout clean
If your grout has darkened, or the floor still looks streaky no matter what products you use, it’s time to call a professional cleaning company. A professional clean can:
Restore the original colour of grout lines
Remove embedded dirt, grease and bacteria
Lift stains from natural stone and textured tiles
Leave floors hygienic, slip-resistant and easier to maintain
Optionally reseal grout and stone for longer-lasting protection

How often should you clean tile and grout?
For most households, a professional deep clean every 12–18 months keeps tiles looking their best. Busy family homes, kitchens or bathrooms may need it more often, while lower-traffic areas can go longer. Sealing grout after cleaning helps protect against future staining and makes routine mopping much easier.
