What you'll learn in this module

  • Which chemicals are safe on grout and tile, and which to avoid
  • The right tools for grout and tile cleaning
  • The correct technique for best results

Choosing the right chemical

Chemical choice is critical with grout and tile. The wrong product can attack grout, etch natural stone, or leave a residue that attracts more dirt.

General dirt and grime

Alkaline or neutral cleaner

An alkaline all-purpose cleaner, or a neutral floor cleaner for routine work.

AvoidBleach as a first choice. It whitens but doesn't deep clean.
Mould and mildew

Mould remover

A fungicidal cleaner, or diluted bleach on ceramic and porcelain with white grout only.

AvoidBleach on natural stone or coloured grout.
Grease and fat

Alkaline degreaser

A strong alkaline degreaser, given proper dwell time. Typical in commercial kitchens.

AvoidNeutral cleaners. They aren't strong enough for heavy grease.
Limescale and minerals

Diluted acid descaler

On ceramic and porcelain only. Wet the grout first, keep contact short and rinse well.

AvoidAny acid on marble, limestone or travertine. It etches them permanently.
Ingrained grout soiling

Specialist grout cleaner

Used with firm agitation from a grout brush.

AvoidAbrasive powders that wear away the grout surface.
Golden rule: check the surface before you choose a chemical

Keep acids off acid-sensitive stone, and use them sparingly and carefully around cement grout. Never mix bleach with an acid or any other cleaner, because it can release toxic gas.

The right tools

Essential

Grout brush

A narrow, stiff-bristled brush that works soiling out of grout joints.

Floors

Deck scrub brush

For scrubbing larger tiled floors. Use with a cleaner and allow dwell time.

Ceramic and porcelain

Steam cleaner

Loosens soiling without chemicals. Not for natural stone, where heat and moisture can cause damage.

Large areas

Rotary scrubber

With a grout brush attachment, it's far quicker than hand scrubbing on big commercial floors.

Finishing

Microfibre flat mop

For rinsing and finishing. Lifts chemical residue without over-wetting.

Correct technique

Follow this sequence for the best results on tiled floors.

1

Sweep or vacuum

Remove loose debris first.

2

Apply and wait

Use the correct dilution and leave it for the dwell time on the label. Don't let it dry on the surface.

3

Agitate

Work the grout lines with a grout brush or rotary scrubber.

4

Rinse well

Use clean water. Residue left on tiles attracts dirt faster.

5

Dry

Dry the floor, or let it air dry fully before anyone walks on it.

Dwell time matters

If you scrub straight after applying, the chemical has no time to work. Let it sit first and you'll get much better results.
