Cleaning Dirty and Dull Sandstone Kitchen Tiles

To clean this floor, I first mixed a strong dilution of Tile Doctor Remove and Go, which is multi-purpose stripper and cleaner. The product strips away any old sealer on the tiles and draws out ingrained dirt, stains and heavy grease build-up. It always provides consistent results and it can be used it on all kinds of tile, stone and grout to great effect.

I applied the product and left it to soak for roughly 20 minutes to allow time to penetrate the pores of the stone and reach the deeply embedded dirt. Next, I scrubbed the floor using a specialised buffing machine fitted with a black scrubbing pad to get the stone clean. The resulting dirty cleaning slurry was quickly soaked up using a wet vacuum and after rinsing with water I used the wet vacuum again to get the floor as dry as possible before leaving for the day and allowing the floor to dry off fully overnight.

Upon returning to the property the following day, I tested the floor with a damp meter, checking for any excess moisture that could prevent me from sealing the stone.

Thankfully the floor proved dry and I could seal the floor using two different types of sealer. First, I applied a coat of Tile Doctor Colour Grow, which is an impregnating sealer designed to fill the pores of the tiles to block ingrained dirt, as well as to enhance the natural colours in the stone.

By itself, Colour Grow provides a natural-looking matte finish, but in this instance the customer had requested a low-sheen finish, so I also applied Tile Doctor Seal and Go. Seal and Go is a water-based acrylic sealer which provides both a stain resistant surface seal and a durable low-sheen finish.

Looking at the before and after photos, you can see the floor underwent a real transformation. The deep clean really restored the condition of the Sandstone, while the addition of robust sealers will ensure that it is easy for the customer to keep clean in the long term. Needless to say, the customer was really pleased with the result!

Here we have an interesting situation in which an old Flagstone tiled floor had been salvaged from a cottage approximately 30 years ago and subsequently reinstalled at a house in Ledbury, a small market town which lies to the west of the Malvern hills in the North of Gloucestershire. Since being reinstalled, the Flagstone tiles had been barely touched in terms of maintenance for three decades and so the stone and grout were naturally in need of a deep clean and seal!

The property owner had heard about the natural stone tile restoration services Tile Doctor provides and so booked me in to see what could be done to improve the condition of his floor.

Cleaning a Dirty Flagstone Tiled Floor

My first job in the cleaning process was to distribute a mixed solution of two cleaning products across the floor. These products were Tile Doctor Remove and Go, which is a multi-purpose stripper designed to remove old coatings and sealers, as well as any adhesive and paint stains, and Tile Doctor NanoTech HBU, a powerful cleaner which utilises nano-sized particles to penetrate difficult-to-reach areas of the stone to eliminate deep lying dirt and stains.

This potent cleaning solution was left to dwell on the surface of the floor for 45 minutes before being worked deep into the stone with a poly brush fitted to a buffing machine. The resultant cleaning slurry was then hoovered up with wet-and-dry vacuum. Next, the floor was rinsed and cleaned with just clean water and the slurry was once again hoovered up.

This left the tiles clean and fresh, so I turned my attention to cleaning the grout lines in detail, which also involved spot cleaning any stubborn grout smears with Remove and Go and Tile Doctor Acid Gel, which is a blend of Phosphoric and Hydrochloric acids in gel form designed to remove stains of this kind.

When satisfied with the result of the cleaning process, I rinsed the floor for a final time with fresh water, hoovered up as much moisture as possible with a wet vacuum and left the stone to dry off fully overnight.

Sealing a Flagstone Tiled Floor

On arrival at the property the following day, I checked the floor for dampness with my damp meter. The test proved that no excess moisture was present, so I proceeded to give the Flagstone a fresh seal.

With regards to sealer choice, the customer had requested a natural-looking matte finish to match in with the rustic characteristics of the Flagstone, so I used Tile Doctor Colour Grow – which provides exactly that. Colour Grow is a durable impregnating sealer that also enhances the natural shades in the stone to really bring the whole floor back to life. Roughly an hour was left between the application of each coating of sealer to allow the floor dry before applying the next.

The result was a noticeable improvement in the condition and appearance of the Flagstone – and the customer couldn’t have been happier. It’s always satisfying to breathe some new life into old natural stone tiles.
