We recently received a request from the Manchester headquarters of a global engineering and construction company which was founded in 1911 and now operates in over 160 countries. The company contacted us because they were keen to restore the tiled walls and floors in 20 different toilets and kitchens throughout the offices.
It would be a big job, but we were more than happy to respond to the enquiry. We agreed a complimentary visit to the office for us to test clean one of the floors to show what kind of results could be achieved. The management team at the offices was very impressed with the results of the test clean and asked us to complete the whole job.


Cleaning Discoloured Grout Lines
As there were 20 different rooms to clean and recolour, our team worked in a couple of rooms at a time to ensure firstly, that we got the job done in time and secondly, that we wouldn’t disturb the normal operations of the offices.
The process was as follows. To clean the grout, we used a strong mix of Tile Doctor Pro Clean, a strong Alkaline-based cleaner which reliably gets the job done in situations where most run-of-the-mill cleaners won’t. We applied the Pro Clean to the grout lines and tiles and left it to dwell for about 10 minutes. We then scrubbed the grout lines with specially designed grout brushes and followed by cleaning the tiles with a black scrubbing pad fitted to our rotary machine.


Recolouring the Wall and Floor Grout Lines
To recolour the grout lines, we used the Grout Colourant from Tile Doctor’s own range. Available in ten different colours, this is a brilliant product as it rejuvenates and also seals the grout. The fact that the colourant is epoxy based will also make future maintenance easier, as you can just wipe off the dirt.

For the floor grout lines, we used the Natural Grey colourant and for walls we used White. The application of the colourant is simple yet quite laborious when working in large rooms. After finishing, we wiped off any excess product.

Tile Doctor Grout Colourants form a protective barrier on the surface of the grout that will protect it from future staining and also make it much easier to clean.
