Details below of a Sandstone Fireplace surround from a house in Thame, Oxfordshire. The fireplace had never been cleaned as the customer did not know where to start and so gave us a call.
Sandstone Fireplace Cleaning
To clean the fireplace I used a diluted mixture of Tile Doctor Pro Clean and NanoTech Ultra Clean which combines the cleaning power of Pro-Clean with the tiny abrasive particles in Ultra Clean to produce a very effective cleaning product that is safe to use on Stone. This was left to dwell on the stone for a short while in order to let it soak in and work on the dirt before scrubbing it into the Sandstone with a hand brush. This process did a good job cleaning the stone and once I was happy with the result the soiled cleaning solution was removed using a wet vacuum and the stone was rinsed with water to make sure all the chemical had been removed.
Sandstone Fireplace Sealing
When dry the Sandstone was sealed using a couple of coats of Tile Doctor Colour Grow which will protect the stone going forward as well as bringing out the deep colour in the stone. To finish the job off I removed the grate and cleaned it up using some grate black to make it look new again before putting it back; last step was to remove the protective strip I had put around the fireplace to protect the wall and carpet and the job was done.
As you can imagine the customer was quite surprised by the results and hadn’t realised what a wonderful fireplace they had until now.
