Dealing with Flagstones Damaged by Strong Cleaning Products in Cumbria

This customer in Grange-over-Sands, a town on the Morecambe Bay, contacted us because an oven cleaning company had spilt a strong cleaning solution onto their Sandstone Flagstone Kitchen tiles, damaging them. The customer hadn’t realised the damage until after the oven company had been paid, and because nothing had been said at the time the cleaning company unfortunately wouldn’t accept responsibility. When we arrived at the property, we were asked to do a spot clean on the affected tiles, however to do so would have resulted in a patchy finish compared to the rest of the floor. However, we could see that the rest of the floor was well overdue a deep clean and the sealer was past its best. So, we suggested the best course of action was to deep clean and reseal the whole floor to ensure a consistent finish across the tiles.

Cleaning a Damaged Flagstone Tiled Floor

The customer agreed to the work, and we started on the same day. To begin, we used a Coarse 200 grit diamond encrusted burnishing pad fitted to a heavy weight buffing machine to grind away the damaged layer of stone. This worked well on about 90% of the area, but the harder to reach spots needed a chemical clean, so Tile Doctor Oxy-Gel cleaner was applied. This is an alkaline-based gel cleaner that is effective for neutralising acidic stains. The product was left to dwell for 30 minutes and then scrubbed into the tiles, before being rinsed away. Following this, we extracted the dirty solution off the tiles using a wet vacuum.

Sealing a Flagstone Tiled Floor

Since we used quite a lot of water to rinse away the chemically-infused cleaning solution, we had to leave the floor to dry overnight before we could seal it. This is really important because excess moisture can cloud the sealer and damage its performance. Arriving back at the property the next day, we ran some damp tests. Once satisfied that the tiles could be sealed, we applied four coats of Tile Doctor Seal and Go. This sealer provides an aesthetically pleasing, low-sheen finish and is fully breathable. Most of the old Flagstone tiled floors found in properties don't have a damp proof membrane installed underneath them, so a sealer which allows for moisture vapour transmission is essential.




The customer was very happy with the work, not only because we restored the condition of the damaged tiles, but also because we were able to drastically improve the overall appearance of the floor. We recommended that the customer use Tile Doctor Stone Soap as a regular aftercare cleaner. This product not only cleans the stone, but adds to the natural stone patina by maintaining and enhancing its shine.
