Can anyone help with the problem.
The sandstone fireplace as been used for many years with a log burning stove. The stains are what looks like pink spots which could be red wine and black areas where I think the logs have fallen.
I have tried scrubbing and using bicarb, no success.
I read somewhere use an oven cleaner, but a bit concerned this may make it worse.
I'm looking for a tried and tested successful solution, don't want to make the situation worse.
Thank you
