How long does Grout Brush last?
Typical lifespan
Around 100 metres of stone-based grout lines per brush under normal cleaning pressure, before the bristle tips begin to soften. Treat it as a rough guide, not a fixed number.
What changes lifespan
Grout type, surface texture, and pressure applied. Lighter detail work on fridge seals, door runners, and shower tracks barely touches the bristles, so one brush stretches much further.
When should I replace Grout Brush?
⚠ Time to replace
Bristles are permanently splayed outward and no longer spring back. Strokes feel soft with less resistance than they used to. Scrubbing effort increases but residue stays behind in the grout line.
✓ Extend bristle life
Use firm but controlled pressure. Excessive force speeds up wear without cleaning any faster. Rinse and dry the brush fully after each use. Skip harsh chemicals, bleach, and very hot water.
Grab a fresh one when bristles splay or soften beyond reshaping.
