How long will Grout Brush last?Updated 3 hours ago

TL;DR
Around 100 m of grout lines under normal pressure. Replace when the bristles flare, bend or lose scrubbing bite.


Typical wear rate

Our lab tests on stone-based grout suggest one brush handles roughly 100 metres of grout before bristle tips soften.

Checkpoints for replacement

  • Bristles permanently splayed outward
  • Stroke feels “mushy” with less resistance
  • Scrubbing effort increases but residue remains

Extend its life

  1. Use firm but not excessive pressure.
  2. Rinse & dry fully after sessions.
  3. Avoid harsh chemicals or very hot water.
