Removing Algie from Bath Stone Cills

Bath Stone is a material that we don't often encounter. A variation of LimestoneCardiff was quite upset that her Bath Stone window sills had become so unsightly over the four-year period since her house was built, so much so that she contacted Tile Doctor to see if we could help.

Cleaning Dirty Bath Stone Window Sills

While at Tile Doctor we most often work on tiled floors, patios and shower cubicles, I was more than happy to assist in this situation. I popped round to the property to carry out some initial cleaning tests on an inconspicuous area of one of the window sills. I applied Tile Doctor Pro Clean, which is our high alkaline cleaner, since it's a very versatile and reliable product, and is suitable for use on most kinds of natural stone. Some fantastic results were achieved quickly, with Pro Clean working efficiently to remove the green and black algae that I presumed came from the trees which were plentiful around the property.


With the test clean a success, we agreed a date to complete the job. I returned on the agreed date with a ladder to treat the rest of the sills using Pro Clean, including the one on the first floor window.


Before carrying out the work, I tested the stone for moisture and the readings were sky high. Therefore, I suggested to the customer not to seal the stone, but instead to maintain it using the same cleaning process as I had undertaken.


The outcome of my restoration was brilliant, so now when the customer feels that the sills need to be rejuvenated again, she can do so very easily.
