Kitchen and bathroom tiles get plenty of attention during a bond clean, but the grout between them is often left as an afterthought. That's a mistake, because discoloured grout is one of the more visible signs of a property that hasn't been properly maintained, and it's exactly the kind of detail an experienced property manager notices during a final inspection.
Why grout discolours over time
Grout is porous, which means it absorbs moisture, soap residue and general grime far more readily than the tile surface itself. In bathrooms especially, ongoing exposure to shower water and steam accelerates this process, leading to grey or black discolouration along grout lines within a year or two of a property being occupied, even with regular surface cleaning.
Why regular cleaning products don't fix it
Standard bathroom sprays and a scrubbing brush can lift surface dirt, but they rarely penetrate deep enough into grout to remove embedded staining or mould. This is why grout that looks clean immediately after a DIY clean often reverts to a duller appearance within days, once the surface layer of cleaning product wears off.
How professional grout cleaning works
Professional tile and grout cleaning uses a combination of targeted cleaning solution and mechanical agitation, often with a rotary brush or steam-based system, to lift embedded grime from within the grout itself rather than just the surface. This produces a noticeably brighter, more even result than manual scrubbing, and the effect lasts considerably longer.
Booking it alongside your bond clean
Since tile and grout cleaning uses different equipment to a standard end of lease clean, it's usually booked as an add-on rather than included by default. If your bathroom or kitchen grout has visibly discoloured over your tenancy, it's worth flagging when you book so it can be scoped and quoted alongside your main clean.
What to expect from the result
A professional clean won't necessarily restore very old, heavily stained grout to its original colour, particularly if it was never sealed. In most cases though, the improvement is significant enough to satisfy an inspection, and we'll always be upfront during your quote about what's realistically achievable for your specific property.
