Ceramic tiles are usually glazed and therefore non-porous, so when the floor starts to lose its appearance there’s a good chance the problem relates to the grout. This is because the top layer of the Cementous grout is rough and will attract a build-up of dirt over time.
Once dirt becomes ingrained into any porous surface, tile or grout, it isn’t easily removed using supermarket cleaning products. In fact, many standard cleaning products are acidic which can have a negative impact on many surfaces (always read the label before use).
I mention this as I was contacted about restoring a Ceramic tiled floor at a house in my local area of Gloucester. Interestingly the tiles as well as the grout lines had become badly soiled and discoloured, and the property owner was at a loss at how to get them clean.
Deep Cleaning Ceramic Tile and Grout
The tiles were located in the hallway which is one of the busiest areas of any house and as a result had seen a lot of dirt being trampled in and now required a deep clean.
To get them clean I applied Tile Doctor Pro Clean, which is our reliable high alkaline cleaner. I used a strong dilution and let it soak into the Tile and Grout for a short period before scrubbing it in using a buffing machine fitted with a scrubbing pad. This helped to remove any initial layers of ingrained dirt:
Next, I applied Tile Doctor Remove and Go, which is designed to remove heavy instances of soil as well as old dealers, adhesives, and paint stains, to the grout lines. This was left to soak for 20 minutes and I then scrubbed the grout lines with a stiff grout brush.
When I was satisfied that all of the tiles and grout line was clean, I rinsed the floor with water which was extracted with a wet vacuum and then dried all grout lines with a heat gun.
Sealing a Ceramic Tiled Floor
The customer was concerned that the grout lines would darken again over time due to more ingrained dirt, so I recommended that they were sealed in order to protect them.
So, after checking the grout lines were dry a moisture meter, I sealed the grout lines using Tile Doctor Ultra Sealer applied with a pipette. The pipette ensures the sealer is delivered exactly where its needed. Ultra Seal is a solvent-based impregnating sealer designed to provide maximum protection against ingrained dirt and staining.
I should point out that Ceramic tiles are glazed and therefore won’t take a sealer. I think you will agree the floor look much better after a fresh clean and seal. Certainly, the customer was very happy and the hallway looks like new!
