Tile & Grout Cleaning in Old Toronto

Tile is glazed, sealed, and essentially non-absorbent. Grout is the opposite - a porous cement product full of microscopic voids that behave exactly like a sponge. Everything that lands on that floor eventually ends up in the grout line, which is why the tile still looks fine and the lines between it have gone from pale grey to charcoal. The mop is a large part of how it got there. You dip it in a bucket, the water gets dirty within minutes, and then you spend the next twenty minutes distributing that dirty water across the floor. The tile sheds it. The grout drinks it. Every mopping session moves a little more soil down into the joint and leaves it there. Bathrooms have their own version. Soap scum and body oils build a film on the grout and hold moisture against it constantly, which is exactly what mould and mildew need to establish. Once it is rooted into the pores, a surface spray is cosmetic - it lightens what you can see and leaves what you cannot. None of this is a cleaning frequency problem. It is a method problem. Surface cleaning cannot reach into a porous material, and no amount of scrubbing pulls out what is already absorbed.
