Grout Cleaning

As most grout is porous, it will absorb water and contaminants and discolour – sometimes more than the tiles around it. When cleaning grout it is important to make sure any cleaning solutions used are compatible with the stone or tile surface itself. Do NOT use any acid based cleaners.

This grout cleaning regime is designed to keep good-condition grout maintained. If grout is flaking or pulling away from the joints, it will need to be replaced. If staining or discolouration can’t be removed, a specialist such as Slique can professionally clean the grout and even change the colour of the grout if so desired.

Cleaning Grout:

  1. Vacuum
  2. Vacuum, sweep or wipe to remove loose grit from the grout lines.

  3. Scrub
  4. Scrub grout lines using a special grout cleaning microfibre sponge, wetted with a little water. Rub the sponge back and forth along the grout lines firmly.

  5. Allow to dry
  6. Allow the grout lines to dry before evaluating the results. The microfibre grout sponge will clean up most dirty grout, but for very stained grout it may be necessary to use chemicals – in which case continue as follows:

  7. Scrub with chemical
  8. For very stained grout, you can also use a light solution of tile cleaner suitable for your tiles such as Slique Heavy Duty Tile cleaner. Match the cleaner to your tiles – for example, if you have marble tiles, it’s important to use a non-abrasive neutral chemical so you don’t damage the marble. Complete a manageable area at a time (say 3 or 4 sqm). Use a grout sponge or a soft brush / broom to work the solution into the pores of the grout.

  9. Soak
  10. Leave the solution to work for a time (several minutes) and then scrub again.

  11. Extract
  12. When the solution has lifted out the dirt, remove the liquid and dirt using an old towel or clean, dry mop.

  13. Rinse
  14. Rinse using clean water.

  15. Dry
  16. DO NOT leave the grout to dry naturally. Make sure all the surrounding tiles are wiped dry too.

  17. Repeat if necessary
