Tile & Grout Cleaning Hacks for Hard-Water Perth Bathrooms (Slime-Free Shower in 15 min)

Perth scheme water averages 130 mg/L of dissolved minerals, so calcium crust forms on shower walls twice as fast as in Sydney or Melbourne. That white haze traps soap scum, breeds pink slime and leaves grout looking older than it is. Luckily, a focused quarter-hour once a week keeps hard-water damage—and your cleaning bill—under control.

1 minute: Pre-heat the room with steam

Shut the shower door, crank the hot tap for sixty seconds, then switch the water off. Steamy air softens mineral deposits by almost one-third before you lift a cloth.

3 minutes: Spray an acid rinse that is safe for grout

Fill a bottle with equal parts white vinegar and warm water, then add a teaspoon of biodegradable dish soap. Mist tiles and grout lines generously and let the fizz work while you move to the next step. (Natural-stone owners should swap vinegar for a citrus-acid product labelled “pH-balanced for stone” to avoid etching.)

4 minutes: Activate grout pores with a baking-soda scrub

Dip a microfibre cloth in warm water, sprinkle it with bicarb soda and buff tiles in overlapping circles the size of a dinner plate. The mild alkali neutralises leftover acid, lifts soap scum and polishes glaze without scratching.

5 minutes: Target persistent lines with a peroxide paste

For darkened grout, mix two parts baking soda with one part 3 % hydrogen peroxide. Apply with an old toothbrush, wait two minutes, then rinse. Oxygen bubbles dislodge organic stains that vinegar alone misses.

2 minutes: Rinse, squeegee and seal the win

Rinse walls with cool water, pull a squeegee from top to bottom and wipe fittings dry with a clean cloth. Finish by misting a fluoropolymer grout sealer once every three months; it cures in ten minutes and blocks future calcium attachment by up to 70 %.

When fifteen minutes are no longer enough

Etched glaze that feels rough, black mould buried behind silicone or efflorescence bleeding through stone tiles signal the point where household remedies plateau. A visit from Add Bhutan Cleaning’s professional tile-and-grout team brings low-moisture steam, orbital scrubbers and a five-year penetrating sealer—cheaper than re-tiling and safe for septic systems.
