Q: Can you tell me the best way to clean a stone fireplace is it with detergent and salt as with a brick fireplace or should I use something different. The fireplace is the original walls of an old fishermans cottage. Would appreciate your help. Carol.

A: We've got some details on how to clean a brick fireplace on the site here; http://www.bubsydogdiy.com/trade_secrets/misc-how_to_clean_up_a_brick_fireplace_100334.php and the first two steps should be usable on stone as well as brick (salt/detergent then vinegar), but I wouldn't use harsh chemicals on a stone unless it's a hard stone like granite (igneous stones). Something like sandstone (sedimentary stone) shouldn't be cleaned with normal household chemicals, although I'm sure you can find a specialist product. In either case, it's in your best interests to test your intended cleaning process on a small area first, just in case the stone is sealed, or you get an unforeseen reaction.

If you know what kind of stone it is, let me know and I can investigate further, alternatively send a photo of the fireplace and I'll see if I can ID the type of stone for you.

In the interim I ordered a stone cleaner and it certainly has made a difference.   The stone is granite and has stood up well.   Thank you for your help and your website is very interesting and informative.

Thanks,

Carol
