I have a commercial pool thats about 100 years old ( with modern modifications). The ceramic tiles on the floor area are original. We have been begged by just about everyone not to replace them. It looks soo dirty. Our comepetition is more expensive.....water quality is horrible....and their pools are packed all day. Im lucky to get 5 people in an 18 hour day. The water and inside the pool look nice.....just getting to the pool...people think they will get a disease. Its just old age stain....not sure what that is exactly.
you could try an acid base cleaner on the tile . These type of stains may be just old age though and i know every one says don't replace old things but if these tiles are past there prime? i am sure you can get a modern tile that has the same look
I okorder /... Re-sealing the tiles is not a permanent solution. Another alternative is to find matching tiles, and remove a strip wide enough for a walkway, and re-tile with the new, modern tiles. Sometimes old meets new can look terrific.
