Removing Efflorescent Salts from Terracotta with Tile Doctor Acid Gel in Green Hammerton Yorkshire

These photos came from a property in the village of Green Hammerton on the outskirts of York. The terracotta floor tiles were fairly old, we believe around 30 years and had been the victim of a leaking dishwasher which had resulted in staining and efflorescent salt deposits. You can see this next on the tiles next to the kitchen kick boards in the photograph below.

The client wanted the staining removed and the tiles restored to their original condition, however they were happy with a large part of the floor and so only wanted the impacted section cleaning. I was happy to do this however, I did raise a concern that the section I would be working on wouldn’t blend in with the rest of the floor.

Cleaning a Terracotta Tiled Kitchen Floor

I first treated the tiles with Tile Doctor Remove and Go to clean and remove the old sealers. This was applied in the usual way of spraying the affected section with a strong dilution, letting it soak in for ten minutes and then scrubbing it in with a black pad fitted to a rotary machine. The resultant slurry was then removed using a wet vacuum.

To cure the efflorescent salt problems the tiles was then treated to an acid rinse using Tile Doctor Acid Gel. The gel was applied to the floor and scrubbed in with a deck brush before being rinsed off and extracted as before. Being a gel its is very easy to control allowing the acid to dissolve the alkaline salts in the floor and further cleans the Terracotta to remove old grout stains.

Sealing a Terracotta Tiled Kitchen Floor

I let the tiles dry out for a few days, then used a handheld polishing machine to remove any residues and prepare the surface for a fresh sealer. I used a few coats of Tile Doctor Colour Grow as a base and then a light coat of Tile Doctor Seal and Go Extra for the finish to match the rest of the floor. This saved the client the expense of having all the floor stripped, deep cleaned and re-sealed. My client was happy with the result which had solved their problem.

For aftercare cleaning I recommended the use of Tile Doctor Neutral Tile Cleaner to keep the floor in great condition. This is a pH neutral product which means it ill not strip the newly applied sealer like an acidic household cleaner would. It is mild enough to use daily if needed and has a lovely fresh fragrance. It is therefore perfect for a heavy traffic area such as the kitchen.
