Japanese bathrooms are famously spotless — the result of the right tools and a few smart habits rather than harsh chemicals. Here is how to deep-clean yours the Japanese way.

Use the right tool for each surface

• Long-handled brushes reach the floor, walls and tub without bending or kneeling.
• Fine-fibre sponges lift soap scum from tiles and tubs without scratching.
• Slim, flexible brushes get into drains, corners and the gaps around fittings.

Work top to bottom

Clean from the highest surfaces down to the floor so dust and runoff fall onto areas you have not done yet. Finish at the drain.

Prevent mould and limescale

• After bathing, rinse walls with cool water and squeegee or wipe them dry.
• Ventilate — run the fan or open a window to drop the humidity that mould loves.
• Tackle grout lines weekly with a narrow brush before stains set in.

Less chemical, more technique

With well-designed brushes and regular light cleaning, you rarely need aggressive cleaners. The habit of a quick daily wipe-down beats an occasional heavy scrub.
