How Do You Clean Grout the Right Way?

Clean grout with a purpose-made grout cleaner and a stiff brush, working the cleaner into the joints and rinsing well. Skip harsh acids and bleach on cement grout, since they can erode the joint and strip color. A safe crystal cleaner lifts dirt and buildup without the damage.

Everyday cleaning routine

  1. Sweep or vacuum loose dirt so you are not grinding it into the joints.
  2. Apply a grout-safe cleaner and let it dwell for a few minutes.
  3. Scrub along the joints with a stiff nylon brush.
  4. Rinse thoroughly and wipe the surface dry.

Deep cleaning stained grout

For set-in grime, let the cleaner dwell longer and scrub in sections. Work in small areas so the cleaner does not dry out. After a deep clean, reseal cement grout to protect the fresh surface.

What to avoid

  • Bleach and strong acids can eat into cement grout and fade the color.
  • Wire brushes and metal tools scratch and gouge joints.
  • Oil-based or waxy cleaners can leave residue that traps dirt.

Keep grout cleaner longer

Sealed grout resists staining and wipes clean far more easily, so a seal after cleaning is the single best way to cut future scrubbing. Wiping up spills quickly and a light regular clean beats the occasional heavy scrub.
