Does anyone have any experience in cleaning a limestone hearth and mantle? It's just basic ground in dust and dirt I think. Also there is one tiny spot of blue permanent pen on the lovely cream limestone .
If anyone has any experience of cleaning or any advice for the blue spot I'd be very grateful
Reanimating this thread to say thanks (three years later!) to pagwatch for suggesting a magic sponge to clean a limestone fireplace.
Mine has had tea stains splashed up the left side for months (knocked a whole cup of tea off the side table eek!) and hadn't dared try anything more than washing up liquid, which didn't work, but my newly-acquired magic sponge has brought it up beautifully. It got rid of ALL the tea stains and has smoothed it out somehow so it feels like it did when first installed ten years ago.
